Date Reviewed: September 24, 2007
Favorite Trail:Gambrill Stake Park
Duration Product Used:More than 3 years
Price Paid: $600.00
Purchased At:A bike store that is long gone :)
Strengths:I bought it for the frame. It was just what I was looking for in 1995. That's right 12 years ago! I learned to ride on it. The first 3 years were very muddy and abusive. I punished this bike. A bulletproof frame on cheap parts that I could easily swap over time. Since then I have rebuilt it 3 times. Most recently as a touring bike. This is the most versatile frame I have owned and will be riding it for a long long long long time.
Weaknesses:I replaced all the parts I didn't like a long time ago so it is perfect.
Bike Setup:in 1997 I put a Girvin fork on it which is also bullet proof. It is still on. It is built up for touring so nothing too flashy at the moment.
Bottom Line:Find one, buy it.

Date Reviewed: January 1, 2007
Favorite Trail:Day's Bay
Duration Product Used:More than 3 years
Price Paid: $1200.00
Purchased At:VIC Cycles
Strengths:Lasted me 10 years. Light, handled a few good beatings. Cost me NZ$1700 down from NZ$2200 brand new as an end of season special (June 1997)
Weaknesses:Long stem, Flat bars, short fork travel by todays standards. Fork used to 'top out' on take off when new. They settled down after about a year and a service. Doesn't handle running into gorse bushes at over 20mph.
Bike Setup:(1997 model) LX componentry (V brakes, Cranks, Hubs, Dérailleurs/shifters), Judy T2 forks
Bottom Line:Good bike at the time. Fun for XC, but too bouncy for the rutted, tree root-lined, mud-filled single track downhills we have here in NZ. Managed to snap the frame just behind the headset a couple of months ago.

Loved the bike for 3 years, then got a Marin B17 with 6" rear travel, Full XT componentry, Mavic D321 Rims, Azonic bars and stem, Manitou Xvert T's (tricked out to 6") and VP clipless Pedals.
That's when I realised hardtails were for smooth riders and 6" beasts let you get away with murder!!

BOTTOM LINE: Nice and Light and pretty tasty.

Strengths:Solid Build, Fast, Great for Trail.
Weaknesses:Handle Bars, Seat Post, Tires, pretty much what you see as upgrades

Bottom Line:The bike is a sweet yellow, I think it's a 1999 though, not too sure. My first bike with shocks, yep, that's right. I bought it used from a friend who got it too big for her, and it was only riden about 6 times. Me I rode it 6 times in one week and busted the seat and post (6' 220lbs). I have since bent the rear bracket but no biggie. I love this bike, however I am still buying a FS XC bike, most likely the Giant NRS 2 or NRS 3 (depending on how much poop I get from my girlfiend). If you happen to come accross a decent used ATX 870 BUY IT, for weekend trail or XC fun this is an awesome bike....

Strengths:Nice starter bike, all hidden details seems to be hi quality. Excellent shifting.
Weaknesses:RST fork with no damping...
Similar Products Used:Cycle PRO Pinnacle
Bike Setup:RST Mozo PRO fork, LX/STX-RC
Bottom Line:Good quality bike, only changed the transmission after it got worn out from a year of everyday abuse in all weather (think the snow kills...) The RST fork is basically crap but will make forest riding a little bit more pleasant than a stiff fork.
With a better fork I would really recommend this bike!

Submitted by Segev Appelbaum a Racer from Israel
Date Reviewed: June 17, 2000
Favorite Trail:All around the country (of Israel)
Duration Product Used:2 Years
Strengths:It's a durable bike that never let's you down. Thanks to its light and rigid CU92 frame, the ride is excellent. I mean, this bike does just about anything you want it to do,on almost any terrain.

Weaknesses:Averagely equipped. If you want to race with this bike seriously, you need to be ready for a big investment, that pays off at the end.
BTW, the new version is much better equipped and lighter.
Similar Products Used:None.
Bottom Line:The ATX 870 is an excellent choice for those who wish to start racing.
As I'm about to consider replacing my current bike, I'm actually thinking of purchasing the latest version of the 870 (other candidates are confined to Giant only).
The bottom line - A wonderful package for its value.

Submitted by Kerry Warner a Weekend Warrior from Sydney, NSW, Australia
Date Reviewed: April 10, 2000
Favorite Trail:6 Foot track
Duration Product Used:Less than 1 month
Strengths:The bike has very tight frame that will go where you want it to. The lightness of the frame and the really great spread of ratios of the 9 spd cluster let me climb up hills at 7 Kilometres an hour yet still give me enough top end to easily cruise at 30 kilometres an hour.
Weaknesses:The PAINT WORK. I have more chips on the paint work after one month then I had after two years on my Trek!!!
Similar Products Used:I have had a trek 870 and a Wheeler 3000.
Bike Setup:Judy front shocks, cable disc brakes, XT decore running gear
Bottom Line:A great bike for the price which was $AUST1,843. I do a lot of kilometres on the bituman yet wanted a bike that would let me do some serious dirt work. The ATX870 does all of this at a reasonable price. My only concern is the paint is chipping off all over the place from stones. I think that someone without a huge budget but needs a good all rounder should buy this bike.

the strengths are in the components and the performence for the price i got mine for Australian AUD$1600 for that XT Rear Derailer, LX the rest, parallell push V brakes, Mavic X222 rims, super light frame and a quality fork i.e. Judy XC
Weaknesses:
the tyres Wildgrippers while i give them 5 big absolutlely great stars in the mud they are positively dangerous in the dry hardpack and rocks or tarmac where i live. the fork while it has fantastic quality travel especially high speed dampening and seriously next to no stiction it could use a long travel kit to take them from 63mm (2.5in) to 80mm (3.0in)

Strengths:
Excellent frame, well equiped right off the shelf for immediate riding.
Weaknesses:
Cheap bottom bracket.
Similar Products Used:

Bike Setup:
My bike is set up for me, to ride the way I like to ride, and I dont' try to label my riding style, which MTBR should consider doing.This bike is set up with Maxis DH (2.35) Helter Skelter tires for amazing traction and bounce wherever I go. I upgraded the rims to X517's, Judy XC LT fork, bunch of XT and XTR parts, WTB SSTK leather & ti saddle, Race Face crank, 636 pedals and a bunch of other indestructible stuff.
Bottom Line:The bottom line? Well it's been 1 year since I got this girl and she's looking better than ever with some very nice battle scars over her body. The Giant has stood up well and I've upgraded it appropriately. So what if I put DH tires and pedals and hadlebars on a hardtail, it's comfortable and I built up enough strengh so that I don't notice the extra weight. She's bombproof, looks sleek and works even better. What more could I ask!

Bottom Line:

Actually I'am a allweek warrior. I have a Giant ATX 870 that is light and strong (I'm 6'4 237 lbs), believe me its strong. Yes we have trails here in the sunshine state that surprisingly are technical and challenging. The facts are, for the money the 870 is fantabulous and fun, if you want to get sick though upgrade the front forks first then the front derail, because of my personal taste and ease of operation. Again this is my own personal taste and if I wanted the spend alot of money I would buy the upgraded bike at the time of purchase.

Submitted by Richie OFlynn a weekend warrior from Harbord, NSW, Australia
Date Reviewed: August 26, 1998
Bottom Line:

Giant ATX 870 I've taken the bike on some really tough, rocky, muddy tracks and found that the bike just ripped through everything. The only problem I have is that there's sand in the area, it tends to get into everything but the gears functioned 100%, the chain ended up really dry but didn't give any problems and I did buckle the front wheel in an 'out over the handlebars' move but the bike shop fixed it for FREE (1 years free service). The suspension works fine (Judy T2) and the LX V-brakes are excellent, apart from the fact that I had to change the brake pads after a few rides. I changed to clipless pedals which is definately worth doing which gets me great air on jumps and makes bunnyhopping a whole lot easier. One annoying thing about the bike is that, especially when it's clean and new, the cable housing just rips the paint off where ever it comes in contact with the frame and has left some marks bigger that what you'd get from trashing it on the tracks. I guess I won't be too worried about that when the bike has been through some hard times and has some natural scars to compensate for those provided by Giant! Overall, a great all rounder and a pleasure to ride, well done Giant !

I used to have a GT Palomar and just got my 98 ATX 870. So far, the improvement is awesome. This bike kicks ass. Some people told me to stick with GT, but after looking around I thought this bike was really good for the price. I kept my 97 Manitou SX suspension, because everybody says the Judy T2 sucks; and I have found the Manitou to be very reliable. This bike is really good.

Bottom Line:

I bought my ATX 870 two years ago for $700 cdn and I love it.
The frame kicks harsh ass with those killer looks-metalic purple fades into chrome, CU92 oversised tubing and that awsome feel of aluminum. I don't think any other company will ever manage to make a hardtail as good as Giant. It's clear they've put some thought into it. The frame feels so natural, and stiff unlike any other bike I've ever ridden. It's just so much fun to ride! But why the hell does this frame this good deserve such shity components!!! I'd give the components minus five chilis if I could. The only thing remotly standard on my bike is the STX rear deraileur. All the rest is some shimano alivio crap that can't shift worth shit! Not to mention the no name suspension fork with a Rock Shox sticker slaped on it with 0.5 of travel. So I've decided to upgrade. I'm getting XT levers and shifters with Avid 20 V-brakes and SR Suntour top of the line deraileurs and cassette. I'm getting SR Gigia cranks and SR Suntour's MG UL forks with 3.5 inches of travel all for a total of 790 bucks!(use classifieds). once I finish the upgrade, my bike will truly kick ass! If you have any advise, E-mail me.GO WITH GIANT, NO ONE CAN MAKE A BETTER HARDTAIL!

Submitted by Petros Kolyvas a cross-country rider from Bromont, Quebec
Date Reviewed: June 18, 1998
Bottom Line:

Well I've had my 98 Giant ATX 870 for about 4 months now and here's how it's going so far (I just got back from a bombing downhill ride at Mount Bromont where they will hold the World Cup XC finals):1 - The frame is indestructible, typical GIANT quality and bombproof - 5 Chilis
2 - My Judy XC LT (which I had switched from the stock T2) is a dream as well, ok, it's a little on the heavier side, but the Type 3 springs, oil bath (if you can call it that, and Aluminium C-3 cartridge make for 3.25 of usable and almost stiction-less travel. - 4 Chilis
3 - The stock WTB Speedmaster Rims (although without eyelets) and Speedmaster Butted black spooked are durable and light. They come out of true a little easily but then again a lot of wheels do and people just don't notice. - 4 Chilis for the rims and 5 Chilis for the amazing spokes which I've tried to find to put on my new wheelset but they are unavailable unless you get them on WTB wheels.
4 - The LX Rear Derailleur proves that if you're searching for the best orice vs. performance option, Shimano's LX component group is still the best for the money. The STX-RC hubs are very heavy but bombproof as well so there's an upside to all that weight. The front STX-RC derailleur could use a speed increase but it's durable and high quality so I can't really complain. I changed the stock LX V-Brakes for 98 XT Parallel Push V-Brakes with the new pivots. They don't slop and I have not noticed any additional play. As with all V-Brakes, XT, LX, STX-RC, whatever, the GIANT CU92 Frame Material is very flexy and they will fade and cause extreme fatigue if not used with a brake booster (rear only). Try the Shimano Carbon V-Brake Booster... it works like a dream. The Shifters are pretty good and the brake levers are ok. The LX shifters work reasonable well and are pretty durable. The LX Lever are nice in the fact that the cable comes along the handle and there is no stretch. But play develops in the non-rebuildable pivots quickly. At 25$ CND a pop, you can replace them easily. - 4 Chilis for the well thought out component mix.
5 - The LX 4 ARM crank is pretty stiff just like they advertise, only it develops (and if you check out the LX crank section in www.mtbr.com, you'll see what I mean) creaks and clicks that cannot be fixed. I've tried everything and it still makes noise. If you have the money, spring for a decent LX or higher 5 Arm model. - 2 Chilis and not GIANT's fault because the 5 ARM LX crank is not readily available and who knew that the 4 Arm model would suck.
6 - The Tange BB-UN55 bottom bracket is the only true peice of crap on this bike. It's extremely heavy and the spindle bends easily. I replaced this 500g peice of junk with a 180g Syncros Titanium BB. - 1 Chili
7 - The WTB Saddle is great. Period. The Kalloy Aluminum Seat Tube is rated #3 on the list of most durable seat tubes. It may be a little heavy but it'll never break. - 5 Chilis for the seating department
8 - The WTB Velociraptor Kevlar Tires are great. They are predictable and full of traction for all your dirt bitting needs. I got a second set of Maxis Tires for downhilling and dowhill single track because the Velociraptors are very thin - 1.95 vs my new 2.35 tires. But the stock tires are great for starters and all around use - 5 Chilis
9 - The headset is decent and so is the stem, although the bolts in the stem rust a little too quickly.. The stock bar-ends are comfortable and light, and pretty durable too! I can't say much about the handle bar seeing as though I had it switched for a Syncros HardCore handle bar at the shop! - 3 Chilis for the cockpit department
10 - Can't say much about the pedals because I had those switched too! Get some clipless pedals people. I love them so much and you will notice the difference.
___________________________________________
Overall this bike is pretty amazing, reasonably light, and totaly indestructible. I think it earns a well deserved 4.5 chilis (90%). Too bad I can't put that down at the bottom. I guess I'll just have to round up eh? Heh heh!

I have had the ATX 870 for since nov. 96 and it has been good. I have changed the front shox to RST tripple clamps and replaced the front derailer twice. I replaced the rear rim for a rhino after smashing the shit out of it on a big jump. I put on a DH bar and some bear trap pedals but it has been a good bike overall for the price. If I was going to buy one now, I would change the rims, pedals, cross-country bar, and front shox before I bought it if it were possible. I rekon it was a good deal.

Bottom Line:

This bike has to be the best value on the market. Comes with almost full Lx minus the hubs and front derailer. I upgraded the front shock to a Rock Shox Judy XC Long travel for $80 CDN extra. This bike also comes with butted spokes. I don't think you will find a $1140 CDN bike with butted wheels. Heard bad things about the 4 arm cranks. You might want to switch to a 5 arm Lx if the bike shop will do it at no extra cost. Also got Shimano 535 pedals. Fantastic pedal for the price $79 CDN which brings the final cost to $1300. This bike rocks.

I have a 96' ATX 870 I will say it is one of the finest bikes that I have ever ridden. I not a big fan of the componets, but with some up grades it is a great bike at any level of riding. The frame is light and extremely strong. I ride very aggressively and my bike has never failed. I put on a 97' Manitou FS Ti and my bike has never felt better. I give the frame five stars, but because I do not like the componets that come on it that much I will have to give it an overall four.

Giant ATX 840 is a agressive bike to ride, unfotunately it downhills like crap and I got a scarred arm to prove it. The fork angle is a little steep making this bike excellent for climbing, which is what we all ride for! I changed the fork to Manitou Pro-C which I feel last a whole lot longer than RS. Good bike to ride for entry level but I think that FS is the way to go. See you later from my VooDoo ,LTS or Intense!

Bottom Line:

this is the 1998 ATX870, with a high level of components: shimano deore lx group (24 speed), rockshox judy, cu92 frame, shimano deore lx v brakes, shimano stx rc hubs, bull bars, toe clips, velociraptor 44/50 wheel-specific tyres, wtb speedmaster 23 (11.3) wheels, wtb double butted spokes, wtb sst seat.
i have ridden an atx840 for some time now, and find the ride i get from the new atx870 really different. far smoother and more positive. the deore lx group is a pleasure to use, as are the brakes with soft touch servo wave action. the judy is far more of a thinking shock than the indy on the old atx840.
after a lot of hard riding i certainly give the atx870 the finger! (thumb, that is!!) this bike kicks ass! value for money, weight, rideability, is outstanding!

I ride a ATX840 and have just upgraded to XT all round, the bike was great it is now exceptional. If you do not have the dollars to buy a dual suspension bike (Cannondale or top of the range Giants) these are the bikes to go for. I show mine plenty abuse, both downhill and touring. I sometimes ride with panniers and the handling of the bike is still really good. With the XT components braking is really good and shifting has never been this good

Bottom Line:

Actually this is about the ATX860.I bought the Giant ATX860 for a few reasons: First, I had a superb Giant ATX760 for almost 6 years with no significant problems (this bike was not treated kindly). Second, the ATX860 comes with the same great aluminium CU92 frame as the top-of-the-line ATX890. Thirdly, the '98 model has a great component mix for the price (I paid $675US). In fact the '98 model comes with GripShift's new short-action 700 series shifter and rear der. while the rest of the bike is mostly decked out in STX-RC components. Also the ATX 860 comes with Manitou's new Spyder front fork (this fork is far superior to any Indy that I've ridden). Anyway this bike is fantastic! It is everything that I expected it to be and more. It's light, it's nimble, and rides great. For the price nothing else came close. This is the perfect upgrade bike, and I would recommend it to anyone.

I bought my ATX 870 back in August of 96' and have since then been riding it on and off trail every day. I even ride it the winter months with the help of studed tires and I must say that the bike has stood up to all my abuse with only the smallest of problems. For the price (I paid $949.00) this bike is a great deal for those looking for a starter bike with a awesome frame that will last.

I bought my Giant 870 Atx in 1995 and I have been very pleased with it. The alluminium frame is VERY light. It had no shocks, and all stx parts, In 95' it cost $650. It is a perfect bike to upgrade!!! So far I have The Girvin Elite Cross Link shocks, WHICH ROCK! and XTR V-Brakes. It can also take a lot of punishment, this past summer I took it to Moab, Durango, and points beond. I beat the shit out of it and it was perfect.

This past season I sold the Giant 870 at a local bike shop in town. Price per
part, this was the best deal on the floor. Giant has a great frame design and
some unbeatable prices compared to other bikes out there cruising around. The
870 is super light with its aluminum frame and STXRC component package. I would
recommend this bike to anybody who has the chance to buy it or to ride it.

Bottom Line:

I have an 85 ATX870 and have found it to be very reliable. I have no complaints
about the quality of the frame or components (except for the stock Shimano
chain). I replaced it with a Sach's chain and have been much happier. The
Shimano chain's break frequently. However, after riding some more expensive
bikes (better components, front shock, etc) I've found that the 870 is not
nearly as much fun to ride as a more high end bike, nor does it corner as well on tight singletrack. But for the price and quality, I'll give it 5 stars.

I'm very new to the sport of mountain biking and the ATX 870 is my entry bike
I love it so far, but I'm not shure I know enough about the sport to really give a good rating. I would like if someone has the time to suggest some ways I can up grade the the bike i.e. (specific components) I'm not very happy with the overall shifting and brakeing of the bike. Also I do not have a front shock on the bike. Overall I'm happy with my Giant. Thank you!

I hope my suspension doesn't shoot me in the balls! We all have to be careful. I know someone who this incident happened to. He isn't happy. Apart from this minor detail, the bike is very good value in Australia and I enjoy riding around the dandenongs (a big mountain) and storming down the hill afterwards.

Bottom Line:

As an entry level bike it really can't be beat. My strategy was to buy a bike that had a good frame and upgrade from there. The things I would replace first are: Front forks (they suck), front deraileur (it shifts worse than my dead grandmother), SPDs need to be added and the saddle aint thay great either. The frame (as with all Giant Al. frames) is probably one of the best commercial frames about.

Giant's CU92 frames are quite possibly the best on the market. It's light,
stiff, and stronger than hell. I'd like to see any other company even come close
to matching Giant in component selection.

Submitted by Jim Tsacalakis a weekend warrior from Adelaide, South Australia
Date Reviewed: December 2, 1996
Bottom Line:

Model = ATX - 870 (97 Model)
This bike is most probably the best value in its price range
(in Australia anyway) I got mine for $1420 (AUD) and considering the
equipment, I reckon I scored big time. The CU92 frame feels very
strong and is also extremely light. Giant give 20 years on alloy
frames. Try getting that from Trek (5 years) or Gary Fisher (5 years)
The reason I mention these two is I was going to buy either the 870, a
Gary Fisher Big Sur or Trek 930 SHX. The warranty was a big factor.
The Giant has Indy XC's as opposed to Indy C's on the other two.
The Giant also has an LX rear derail and STC-RC everything else.
To be fair the other two are still excellent bikes and the Big Sur
has an Easton alloy frame. But they won't back up supposedly the best
alloy there is (easton) with a decent warranty. 20 years from Giant
shows they are extremely confident in regard to the integrity of their
CU92 frames.
My only complaints are that the seat is really uncomfortable (maybe
I'm not used to it yet) and it only comes in one colour. These are
small factors against a great all round bike. There are probably
better deals in the US for the money, but if you've got 1500 smackers
in Australia, this would be hard to beat.

This is a fabulous rig for the clams. I used to be a roadie, but I got tired of fighting
my desire to ride down stairs, across rocks, etc. I was a little weary of diving in to
a huge dollar investment, though, so I went with the ATX 870. With apologies to
the boutique frame makers, Giant's oversized CU92 makes for one supple ride.
I passed-over Fisher's Hoo Koo E Koo for this bad boy, and I've never regretted
it. I have pledged my loyalty to Giant. Next bike -- a Giant, for sure!

Date Reviewed: June 14, 1996
Bottom Line:

After the theft of my beloved '87 stumpjumper, I am testriding every bike
in my price range under the most strenuous conditions I can find- a
construction site complete with 3 foot cliffs, deep sand, 8' piles of
gravel, 30' stretches of thick mud. Unlike the other reviews, all these
bikes will have been tested within a couple of days of each other, so you
can see what one person thought of a variety of bikes.


This bike absolutely typifies the aluminum feel. Light, stiff, kinda
bouncy. It was one of the better bikes in this price range as far as
keeping balance after bizaare vertical maneuvers, but I didn't feel
that the handling response was as quick or direct as some of the others, like
the two gary fisher bikes I tried today. I would recommend this as a good
mid-leve bike if you are a personal fan of the way aluminum bikes feel. I like
the cromoly feel better... it takes a pretty special Al bike to grab my heart.
3 stars.
