|FSA ISIS CF PRO crankset - Bottom Bracket Compatibility?||BMF82|
Jun 12, 2003 10:29 AM
|Helllllo! I got a great deal on a 2003 FSA carbon fiber pro crankset, with ISIS drive. However I'm currently using an incompatible shimano BB; it's easy to replace I guess . . . but I'm wondering if anyone has any experience with this crankset, and would know exactly which isis bottom brackets (raceface? truvativ?) are most compatible (I'm worried about chainline deviations, etc.) I would use FSA's bottom bracket, but I've heard bad things. Any help would be appreciated! Ciao,

|I've been using FSA Carbon Pro cranks (MTB version) with FSA Platinum Pro Ti ISIS BB for several months without any issues. I've been running this combo since March....lots of training, racing and riding hours and mileage, plus some nasty wet-n-muddy conditions. Just the other night after finishing my 3rd Canada Cup in 4 weeks, I pulled out the BB to check for smoothness, play, etc. It is still rolling smoothly as the day I installed it.
As long as you use the recommended spindle length, any ISIS BB will work.

|Thanks for the info, SS_MB-7! I might just get an FSA BB.
However, if anyone out there has any advice on other good BB's, I could use it! I'm not at all familiar with ISIS, and I've heard conflicting reviews. Thanks for any info you can provide.

|Almost all ISIS BBs are getting bad reviews because of the design of the bearings. The ISIS spline itself is fine. However, when you try and squeeze an over-sized BB spindle into a fixed-size BB shell, something has to give...unfortunately, it is the bearings. There is now a push to oversized BB shells to accomodate new larger bearings for ISIS BBs.
My FSA Platinum Pro Ti has seen a couple improvements for the first FSA Ultimax Xtreme Ti ISIS BB. In particular, the driveside bearing is now a single, over-sized bearing instead of 2 single bearings. The single bearing has the same width as 2 singles. Also, the bearings are now better sealed.

|they weigh 140g and cost $80 (ow). in the MTB world, people tend to wear out the bearings quite fast due to the reasons SS_MB7 mentioned. I think they might last longer on the road, but I've never tried.|

|All you need is the correct spindle length and BB threading (English or Italian). A double FSA crank needs a 108mm spindle length and a triple uses a 118.
If made properly, all ISIS splines are the same.
