Strengths: Read my full review below. Great components for the buck. Provided years of use. Best brakes for the money. Decent fork and wheels.
Weaknesses: Squeaky brakes, though doesn't affect performance. Slightly heavier than others.
Bottom Line:
I have owned and operated the green 2008 GF Piranha since I purchased it in May 08' for $740 new. As of this writing I have probably put over a thousand miles on this bike. The trails in my area have intermediate technicals with logs, moguls, and downed trees. Average trail ride is 10 miles.
This bike has been the best bang for my buck. The components have lasted five seasons and still perform great. In fact, I still have the original Bontrager tires! I only recently needed to get a tuneup, the SRAM X5 really has held up well with minor adjustments from time to time. The parts I have replaced were both done this year, an inner tube and a chain. I actually snapped the chain a couple years ago but was able to fix it and it went this long before snapping again. I'm a big, tall guy, 250lbs, so I changed the seat immediately. I do put more than average stress on bikes because of my weight and the only component other than the chain that may need replacing five seasons later is the crank bearing. It still works fine, just clicks a little. I don't know why other people are complaining about the tire, I have tried other people's bikes with supposedly better tires but I don't notice a difference. I get great grip and phenomenal wear. The Shimano brakes are incredible, I actually had to wax and polish the front rotor because it stopped too well and I have actually flipped over the handlebars! I have never had to change the brake fluid or the pads, it still stops as good as the day I bought it. The Tora 302 fork is actually better than the Dart series that was offered at the time on other bikes. To upgrade from this, I would have to spend $1500 or more before I'd get a noticeably better bike. I just tested out several sub $1600 bikes and I can't justify the upgrade other than saving a couple pounds of weight. To buy a bike with similar quality components today, you would have to spend over a grand. I may retire the bike after next year, but only to get a 29'er.
It's too bad Trek quit making this bike with all the great stuff it had for the price.
Weaknesses: On the Heavier Side, Ugly Paint design (I had a 2006 though --and paint- who cares? Lol), Terrible Tires
Bottom Line:
I had a 2006 Piranha and loved it. It was my first MTB and held up very well on numerous agressive single-track and off-road runs. After one season of riding just about every other weekend (mostly about 10 miles/weekend on single-track) it required a tune-up (mainly brakes), but this can be expected. As others have reported, the tires weren't the best, but the brakes were excellent --until I needed the tune-up. Overall, I would highly recommend this bike to other riders.

Strengths: Great value, very solid. Bought late 2005 (when the 2006 version first came out), and its survived everything. It's fairly light weight, and a similar spec bike now costs nearly double!
Weaknesses: Tyres, utter rubbish. Very little grip, clogged up far too easily. Front mech could be better. The Manitou forks are pretty bad. I rode them into the ground over the six years, and finally gave way earlier this year. Replaced with some OnOne carbon's, and it feels smoother, more comfortable and a lot faster.
Bottom Line:
Very solid bike. The frame is decent, and plenty of chance to upgrade. I've upgraded tyres (a must!) cranks and front mech. The rest is holding solid. The fork isn't the best, but is survivable!

Strengths: Awesome Geometry, Tough, Down Tube Blocks Mud, Handles Very Well
Weaknesses: Heavy, White Set Gets dirty
Bottom Line:
This is an awesome bike, bought a 2009 for 699 and got everything I was looking for. Durable bike with a great fork and hydraulic brakes. Very good price for something with hydraulic brake. The G2 geometry is great for high-speed handling. It has a big cockpit and a short rear triangle which gives you better handling downhill while keeping the wheelbase fairly short. Also it is tough bike. Its taken quite a beating since I bought it about a month ago and everything works fine. The hydro formed down tube is extra wide, and blocks mud coming off the front wheel (not sure if trek intended this or not, but works!) The one downside is that the bike is quite heavy. I'm 15 years old and I can do a substantial bunny hop on it, but nothing huge. I'd rather have a heavy, durable bike than a light, delicate bike, so it works for me. I'd recommend this bike to anyone looking for a durable mountain bike at a good value.
AWSOME bike.I know more experienced riders could probably pick my bike apart with things they don't like but,this is my first mountain bike from a bike shop.When you go from a "retail giant's" bike to a quality bike from a bike shop the difference is amazing.I agree the pedals are not great but,that is the only complaint I have at this time.Lightweight,smooth,and a front fork that actually works !
I know the components aren't the best out there but ,if it ain't broke then why change it ?

Strengths: Good durable components, good geometry
Weaknesses: Tires are junk and the saddle hurts the more your break it in. Brakes might need some fiddling to get working properly.
Bottom Line:
I'm reviewing the 2008 model. Stock, this is a great lower end bike for the most part. The components are solid and reliable. My only complaints are the tires, saddle and brakes. The stock Jones XR tires are heavy, don't grip, and pinch flat like crazy if you run them below 35 PSI. The saddle is plain uncomfortable, and seems to get worse the more you ride it. The brakes work well, but might squeak and sometimes don't work that great. I don't know the specifics, but they're finicky. Overall though, this bike is a great bike, and I highly recommend picking one up.

Strengths: great components for the price! geometry is awesome and overall it is a very solid bike.
Weaknesses: a personal preference, but I wasn't a fan of the saddle. Everyone is going to change pedals for clipless so i can't fault them for cheap flats....
Bottom Line:
awesome bike for the price! it will take about anything in the xc realm and a few drops/jumps to boot! I've loved it. I'm not quite sure why everyone hates the Jones XR tires; if you run more than 30-35 psi you have it pumped up WAY too much. I don't get pinch flats and I run it hard. Just my luck I guess!
Bike Setup: Egg Beater pedals and a new saddle is the only swap so far!

Strengths: Pretty much everything besides the tires and pedals, although I definitely wouldn't mind upgrading the rear derailleur in the next couple months from the sram x5 to the x9 but not in a rush to do that
Weaknesses: The bontrager tires blow, I read all the reviews about how people were getting flats the first day on very basic riding and thought that wouldn't happen to me but sure enough the day I get the bike my rear tire goes flat while doing some regular riding on a very plan trail. The pedals kind of sucked too, only one side actually had grip on it so if your pedals ever slipped off you have to make sure that they are set up the right way.
Bottom Line:
I love this bike, it was a huge step up from my GT Avalanche, I am no longer nervous hitting really technical trails or worried about my bike not being able to break or take a couple foot drop. I love how this bike feels and looks, the G2 geometry is pretty nice it puts you a little more forward which is nice for me because I ride a crotch rocket during the summer too so I'm already used to being in that position. This bike is a great buy for the money I would highly recommend it

Strengths: G2 Geo, Stability, cornering, handling, sturdy, very nice intermediate components, fast despite weight, mineral oil disc brakes!
Weaknesses: tires suck, fork squeaks like a bat-outta-hell, stock pedals are garbage
Bottom Line:
what a bike. no seriously, this was my first TRUE mountain bike and I gotta say, I am truly impressed. From the cornering capabilities to the ride quality, this is a great bike for an even better price! despite the fact that I've owned this bike for 3 months, I've put a decent 100 miles on it for sure and it has not let me down!
however, the tires suck. there's no getting around that but that an easy fix. I could be a lot faster if I trusted my tired but I really don't so I'm more cautious when going fast which is something I'd like to change. But nothing annoys me more on this bike than the Fork. DAMN this thing squeaks!!!! I need to change it ASAP and I'm looking to go FOX for sure.
The rest of the bike however, component-wise, is pretty legit. Don't let the intermediate category of the X-5 setup hold you back because these are pretty legit shifters! I need to adjust mine but that is because I ride this bike like hell and in the 100 miles I've put on it, I haven't had them adjusted once. Now that's a sign you got a great bike here. Seat is also pretty nice! but needs to be broken in and that happens at around mile 50.
over all, this bike is AMAZING for a hardtail but it definitely needs to be broken in. Also, make sure that you get the right frame size because that can make a world of difference! with the right frame you will be IN the bike, not ON the bike ;]

Strengths: G2 Geometry, frame in general. Its very strong. Spectacular components for what your paying, hydraulic disc brakes.
Weaknesses: Tires are kind of sketchy sometimes and wear out odd. Pedals are rubbish, but thats just how bikes usually are so no biggy. I personally don't care for the grips, so i just wear gloves. That's being super picky though.
Bottom Line:
Very good bike for the price, good low intermediate bike. It's a really good starter bike because it comes out of the box good, and you can upgrade as you get more into it and finding what your demands are. It is a good XC bike, that can take some abuse. Very good especially if you like tighter twistier trails and if yoy like boming down a fast trail too because the G2 gemoetry actually lives up to what they say it does.
Bike Setup: Stock, just Time Atac clipless pedals.

Strengths: No major problems at all. Great cross country bike. Climbs well and is very responsive, but I don't recommend bringing it to a freeride park. It got pretty shooken up and everything need to be readjusted.
Weaknesses: Shimano disc brakes tend to squeak on steep declines, stock pedals aren't very good.
Bottom Line:
If you're into a lot of xc, this is your bike. Unless you know what you're doing, I do not recommend this for any drops or big jumps.

Strengths: frame, brakes, ultra responsive, great components package for price
Weaknesses: TIRES SUCK
Bottom Line:
Just feels great! So responsive -G2 is the real thing! I felt instantly confident on it, I chose it over a '10 Cannondale F5. I've beat it up pretty good on it's first two outings. Fork feels good setup loose w/ quick rebound. Front brake makes an awful sound wet, but works just as great. As far as first impressions go, this thing's awesome!
BUT, tires are horrible! They roll fast on concrete and hard packed ground, but loose dirt and clay/mud are it's kryptonite. Bontrager Jones XR came w/ bike. Trade them at point of purchase! I'm going back to Trek this wkend to ask for a trade -Kenda Nevegals work.
