So winter's got me a bit of upgrade fever, plus the fact that my road bike now hangs beside my desk away from the foot of snow outside.
What started with an ultegra bb, that has seen too much rain and is starting to get a bit weathered. Some chainrings that are looking worn, which i'd like to replace with a compact setup. Montreal = Mont Royal, I find myself bottoming out on 39-25 often enough. If you've ever seen footage of the women's world cup up camilien houde's 8-11% you'd understand.
I'd like to upgrade my cranks and bb to an outboard style, fro stiffness, as i'm a bit heavy (175lbs during the season) and am leaning towards either the Truvativ Carbon Rouleur or the FSA SLK MegaExo. Anyone out there have any experiences with either? They both have been out for a season, and I imagine have weathered the tests of a season of training/racing.
Going non-shimano and to compact - which has a 16t difference between rings(from 14t) has me slightly worried about a drop in front shifting performance. but from what i've heard i don't need to worry too much....
I've seen FSA's left crankarm attachment in action- which seems identical to shimano's, basically an aheadset style preload cap and clamp on the left crankarm. However, truvativ's seems a bit weird. I can't seem to figure out how the preload works. From the looks of it you just tighten it down with an 8 key and go. which perhaps explains why i haven't seen a truvativ with a see through bb axle. which brings the question, how does the truvativ thru axle account for variances in the width of the bb shell? it's supposed to be 68mm, but it's always +/- 1mm. and what may start out as 68, might become 67 after a proper facing job (which i gather is essential for an outboard bb)
any input from fellow roadies out there would be greatly appreciated.

I was wondering the same thing. I have some Campy bikes that I wanted to upgrade to a compact. The FSA crank is so much less expensive than Campy's version. I to would like some reviews or opinions.

Mirage and Veloce are now available in allow Compact versions. Priced pretty damn competitively.
Personally, I'd go for the Shimano R700 Compact crank. Likely to have much better shifting.

I am pretty familiar with Tru Vativ, which stands for Truly Innovative. It is a well engineered crank but one point to make note of. The small ring is a 36 I believe, not the 34 as offered on most other compact cranks. Both the FSA or the TruVativ are good cranks. I use a Campy Record compact which cost about $400 so it's a bit more than some of the independant brands. I have noticed a large difference between what some folks sell it for. Some are asking close to $500 and up. Texas Cycle Sport from Austin typically has good prices and dependable service.
