Strengths:    Did not break

Weaknesses:    Difficult to install
Cheap bearings
Poorly sealed


Bottom Line:   
Bad product, will not buy again. Brutal to install, requiring an insane amount of torque to get the seal seated. Never really spun smoothly. After 1/2 a season of wet racing it was shot. rode the rest of the season on it and it self destructed. took it apart and the bearings were toast, races damaged, dirt was everywhere.

to it's credit, it didn't creak, tick or come loose.

Strengths:    None

Weaknesses:    Longevity... This BB just does'nt last.

Bottom Line:   
This is my second Race Face BB. They just don't hold up. The first one lasted 2-3 months and began to make a lot of noise. It got loose and could'nt be repaired. The bearings wore out. This one began to squeal. I pulled it out & discovered that one of the bearings locked up. I got tired of the problems & went to XTR. XTR is o.k. but I should have gone to something with compact rings.

Strengths:    Looks good outside, ...

Weaknesses:    But inside it is crap !!!

Bottom Line:   
Bought this product together with the Prodigy crank. After four weeks I heard a mechanical noise inside the crank. The bottom bracket was broken ! So, they gave me another for free and this one broke after three weeks !! If this is the quality of Race Face, no thank you ! Keep it !
I replaced the crank and bottom bracket by a set of Shimano XT and had no problems with it until now !!

Strengths:    Sexy name

Weaknesses:    soft bearings

Bottom Line:   
Crap. Added $40 to Warrantied Prodigy ISIS (which lasted 6 months including 2 wet months before seizing). The ISIS XS has twice the bearings and became loose after 2 rides. Gradually getting looser as time passes now to 6 months in dry condition (about half as fast as Prodigy failed). I'm 200 lbs and XC ride 4 times a week or more with much climbing. Perhaps light weight riders will have satisfactory performance. I always got 1.5 years minimum use with UN72 before the slightest looseness occurred (looseness was a signal to replace). RaceFace warrantee said expect it to loosen up. Sorry I've been spoiled by inexpensive quality, It's hard to accept crap now and pay more than 3 times the price. I'll be getting an FSA ISIS BB unless King comes out with one soon. The ISIS Turbine crankset is stiff and looks great but my Shimano LX cranks shifted easier. No more RaceFace products for me unless it's free (or they pay me!)

Strengths:    I cann't really say,because it didn't last long.

Weaknesses:    The bearings on the left hand side died within three months on purchase.

Bottom Line:   
I'd like to tell you great things about the XS Isis but I have to say that I was more than disappointed with this product,I thought I was going to fit it and forget it like the Shimano one I had before but NO.We'll wait and see how Advanced Traders(Race Face Suppliers in Oz)deal with the problem.With luck they will fix it get it back to me and I can post the review I think this product can get.

Word of Warning,The old ones seem to have four catridge bearings and the new ones have only two big catridge units instead.Word is the newer ones are stronger.

Strengths:    tough, splined, light enough

Weaknesses:    goes from good to bad really fast

Bottom Line:   
This is an update to my previous review. On a ride last week, as I was climbing a gnarly road hill (to get to the trail) in my 20/28 gear combo, I started getting this horrible scratching and crunching noise. I stopped partway up, checked all the chainring bolts and both pedals, then continued on my ride despite it all. Up until then, my only clue that there might be some maintenance needed was one time when I happened to spin the cranks sans chain and things seemed just the slightest bit rough.

Granted, it has about 2500 miles on it (700 or so of those off-road) and I weigh anywhere from 190-210 with Camelback, but I'd hoped for a little more of the fire-and-forget-it type reliability I got from my pre-spline Shimano UN-72 (XT). You can bet good money that my next ISIS bb will be Chris King, whenever that pops to the surface.

3 chilis to equal out my 5 rating from before, because now I think it's honestly a solid-but-not-outstanding 4 chili product.

Date Reviewed: April 29, 2002

Strengths:    ahhhhh... It's light I guess

Weaknesses:    The spindel began to bend after the first month of riding. I thought it was a bent plate on my MRP at first. It eventually became unrideable after about 6 months. Two other guys on my colligiant team had the same exact problem. I had the XS Dh 128mm BB. I sent it back to the warranty department about 7 weeks ago. I have called and left messages numerouse times and haven't heard back.

Bottom Line:   
Poor product, poor service, and expensive!

Strengths:    Guys, you do not have to buy a new tool *IF you already have a Shimano BB tool. Below I will paste info. DIRECT from the Park web site.

Bottom Line:   
The BBT-2 fits Shimano® cartridge bottom brackets, including those with oversized "pipe billet' spindles. The BBT-2 also fits ISIS Drive cartridge bottom brackets such as Race Face® and FSA® that use the 20 tooth spline pattern. Simply insert the BBT-2 into the splined cartridge and either tighten or loosen using a 3/8 inch ratchet driver or a 32mm wrench.

For ISIS compatible, look at the packaging for the wording, "For removal and installation of Shimano and ISIS Drive cartridge bottom brackets using 20 tooth spline pattern."

Strengths:    strength, durability, smoothness

Bottom Line:   
When it comes to bottom brackets, I'm more concerned about getting an install-it-and-forget-it product than the latest 5-gram-lighter weight weenie titanium model (especially at 190+ lbs.). I have absolutely no complaints about the XS and I've ridden it through rain storms, trails with that thin dust that gets into everything, and mud. Great product, no complaints. I recommend it to anyone looking for a BB that won't quit anytime soon.

Submitted by David a Cross Country Rider from Monrovia, MD

Date Reviewed: November 12, 2001

Strengths:    4 brearings!

Weaknesses:    Too short -- only comes in 113mm

Bottom Line:   
Had to really torque to get the cranks to seat -- 55 ft-lbs! (Race Face said to go as high as 60, but seating was a must). Many torque checks over the first 100-200 miles were needed and they creaked during that time. But, once they seated fully, they've been quiet and dependable.

Had a real problem with the chain line. The left side can't move in because then the crank hits the swing-arm pivot, and I really need to move the right side out (drive side) to get the middle->small downshift reliable. I had to bend the outer edge of my *XTR* front derailleur in to get it to downshift at all -- IMO, you shouldn't have to bend expensive metal to make it work. After lots of careful tweaking on that cage, it's "ok". They really need to make a 116!!!

Rating's based on RaceFace's only making it in a 113 (and I believe a way too wide 135) and forcing everyone to follow their lead.
