Strengths:    Tange cromoly frame is beefy.Wishbone rear stay keeps the frame from flexing during climbs and hard sprints.Straight blade Tange forks look cool.

Weaknesses:    Non really except 26.4 mm seat tube diameter is too small to upgrade to a wider,modern seatpost.Typical of mountain bikes this old.Tange headset needed replacing after efforts to tighten down constantly.Replaced with Chris King.

Bottom Line:   
This is the original 1989 IBOC Pro.Frame design based on John Tomac's winning IBOC Team bike.It's also my first racebike used in my first ever offroad race so it holds a special place in my collection.Favorite phrase to describe this bike still holds true;A Rocket!With some upgrades to modern tires and seats.Still a very good looking bike.A little heavy but still very fast.Climbs and sprints like a rocket.

Strengths:    Frickin' light! Awesome shifting, best ride ever.

Weaknesses:    kind of low bottom bracket, almost sketchy on fast downhills. didn't dig the twist shift either - prefer rapidfire. indys were kind of not supple (but light).

Bottom Line:   
this bike rocked so hard. i beat the poop out of it over and over, ground the hell out of the derailleurs and the chain and never broke a thing. super light at like 22.5 pounds it climbed like a dream and was soooooo nimble on single track, i miss it so much i really do. the only bike i've ever had that i had like no problems with. only a bit of chainsuck, but no big deal. amazing xc racer. sad story: my cousin folded the frame and then the whole thing was stolen out of my garage. if anyone out there that would part with their frame, i want it so bad. please sell it to me.

Date Reviewed: April 12, 2002

Strengths:    lightweight chromoly frame, toptube is slanted, great Shimano XT parts, Avid, Mongoose mix, Hutchinson tires, XT wheelset with Mavic 221

Weaknesses:    Front fork---RS Indy XL
Rear cassette 11-28. Needs a 30, 32 big cog. I cant climb very well on steep stuff with a 28 tooth.


Bottom Line:   
Ultra light chromoly is as light as a good 7005 aluminum but feels better on the trail. Too bad Mongoose doesnt make this frame anymore since I dented the downtube on a boulder. But I rode this badboy all summer long in 98 and 99.

Strengths:    -Lite, LIte, LITe, LITE frame!!!
-Great looking


Weaknesses:    -If you hit any of the tubes the wrong way the carbon gets crushed.
-Easy to break if you are an aggressive rider and weigh alot


Bottom Line:   
Man, did I beat the crap out of this bike! Mine was a '95 model. I broke the frame twice and scratched the hell out of the poor thing. I weigh 200 lbs so you can imagine how hard this bike had it. I even went Downhilling with this thing- AND CRASHED- HARD- MANY TIMES!

It was the best XC bike I ever owned. I loved this bike and only got rid of it in '97 because I bought an Intense Uzzi SL.

Strengths:    
Light frame, good brakes, excellent shocks...


Weaknesses:    
Gears


Bottom Line:   
This bike really kicks ass, specially uphill. I had this bike for about six months and haven't had any problems with it. I ride this bike about twice a week and it takes a lot of abuse. I like the lightness of the frame and the way it handles hard terrain. The whole setup is good. This bike is well worth the price! I give Mongoose two thumbs up
and five chilies!!

Strengths:    
The '92 7005 Al frame very responsive


Weaknesses:    
Not for all people


Bottom Line:   
I still ride this frame at some races depending on terrain, and probably will for years to come. Fast and light frame and very easy to handle in tight places. This is a bike that you need to ride before you buy it, if it feels sweet, get it, if it makes you hurt don't.

Strengths:    
very light, responsive


Weaknesses:    
Gear shifter not numbered, sometimes, but it's OK.


Bottom Line:   
Good bike for the money. However, sometimes the chain kind of squeaking when I had the lowest gear. Tried to lube it, did not work. Other than that, no complain so far.

I have the 1997 Iboc pro sx.It is a light and nimble riding bike.I live on the east coast and the bike is well suited for the tight, twisty, and rooty terrain
we have.The frame has just enough flex to make the ride comfortable.With xt/lx
and a judy xc the bike is 24lbs.A great bike..

Bottom Line:   


Excellent value for the dollar. Super-light, ethereal handling on singletrack. HOWEVER, be prepared for lotsa flex. If your a light rider, its o.k. If your heavy (or clydsdale) your screwed. The Indy SL Long travel - flexy. The 'Ritchy Logic' tubing - flexy. The rims, stem, handlebars - all light, too light; built for weight, not strength - you will have to replace them (shortly). Last beef, paint. The paint seems to chip VERY easily.
However, all of this pales by comparison to a 23.5 Lb, XT grouppo hardtail, that flies.

Bottom Line:   


I got the mongoose proSX in 95...it had the carbon frame and pretty good compenents ....also a great price...but a monthe after i bought the bike i notice flex in the carbon fiber frame....i brought back to the store a few time and they told me it was nothing... but later on i discouver that i already cracked the frame by the bottom bracket all the way thru.....and iu can stretch the frame an extra inch....after the time i never go back to carbonfiber frame for a while..but they gave me credit towards another frame....I picked up a norco team issue frame and that was the best handling frame i ever have..
p.s. i did one race with the IBOC PRO-SX....

Bottom Line:   


yeah i like this bike a lot because before this bike i had a Diamond Back Outlook and any time i rode it the bike would always find a way to break but with this bike you can ride it any way you like to ride. this model is a real trooper because it always handles what u ride over it rarley brakes when you take care of it the right way. thank you to mongoose for the awesome bikes they have come out with over the years. Oh cant forget the handling and control you have over the bike when riding.

Bottom Line:   


I haven't had my frame built up more than a few weeks but man this bike kicks ass. I work at a bike shop and have ridden everthing out there, lemme tell ya that this is how a bike should climb, descend, and feel over the chatter bumbs and ruts that I come across in So. Cal. I know a few old reps and with the addition of a cris king headset there were no more problems to be fixed,
This class piece of work deserves five fat flamin' chilies.

'96 IBOC Pro-SX

I'm thinking of building my old Mongoose IBOC Pro-SX frame into a single speed. When I built the bike in 1997, I put a '97 Judy SL (63mm) fork on it. It was a sweet hard tail back in the day. It came in at 23.5 pounds. Anyway, the '97 Judy SL's axle to crown measurement is about 420 mm to 425 mm ... Read More »

I picked up the frame in the summer of 1996 and built it up in the winter (Jan, Feb, March) of 1997. It's set up nice and light, in the 23 pound range, but at 32, I think it's time to switch to full suspension. Is there any market whatsoever for a used sub-4 pound hardtail steel frame, or am I o ...
