BB Help

[Tom boyd]

I just purchased a FSA Carbon Pro compact crank for my cross bike build. I am now looking at bottom brackets.

I am looking at FSA Pro Platinum TI and the FSA Pro Megaquad TI? Anyone know the real difference or have a preference?

Thanks.

I had a steel FSA Platinum on my cross bike; killed the bearings after two muddy races. Put in a RaceFace, which I have used before with tapered cranks and they held up nicely to mud and rain. FSA rebuilt my original BB with new bearings but may sell it since the RaceFace works so well.
A couple of things with Ti spindles...they may flex a little more than a steel spindle and you may have to put anti-seize on the bolts and the cranks to ensure that the TI doesn't adhere to the mating surfaces. Also, you may to find out if there is a weight limit on the TI BB's before you buy 'em.

I weigh a whopping 145 so I do not believe weight limitations will be an issue.

According to the FSA web site the Megaquad has 2x bearings on each side and improved water sealing. It is listed as a Mountain bike BB. It cost about $10 or so more, but sounds like it is worth it.

I pretty much have to go FSA because of the ISIS mount for the crank.

If you rebuilt FSA is a 68 mm X 108 mm for ISIS and you decide to sell, let me know.

Might be worth the extra $ to buy stronger BB. Oh, the RaceFace BB that I bought to replace my original FSA was an ISIS unit since I have FSA cranks on my bike (not the carbon ones, though).
Gotta look at my other cross bike to see if I will need the refurbished FSA BB for it; if not, I'd be willing to sell it since it is a 68 X 108 BB.
