Need help with Truvativ Stylo crankset
I recently installed a new carbon Truvativ Stylo crankset on my bike, and while I understand that since it is new, the bearings/seals should be a little "tight," so to speak, when I turn the crankset by hand, it doesn't really spin freely at all -- more like it just stays put. If you really spin the crank arm hard by hand, it might turn 1 revolution. Now this is with the bike on the repair stand and with no pedals in the crank arms (to add weight and possible help with momentum). Anyway, since the bike is mostly torn down for an overhaul, I haven't had a chance to ride it yet to see if the bearings will break in. Also, this is my first experience with an outboard bearing crankset (yes, I know I am a little behind the times, being an old school, square taper bb dude), but it just seems a little "too" tight. Thoughts/Suggestions? Thanks in advance.
It's probably fine, just seal drag that will break in over a few rides.
Makes sure your spacer orientation is correct:
- One spacer on each side if you have a 68mm shell.
- Zero spacers if you have a 73mm shell.
Then get yourself a torque wrench and tighten to 35-40lbs.
If your spacers are good and your crank bolt is within torque, then just go ride and it should break in.
And keep that bolt tight! Check early and check often.
It's not where it's made but how it's made.
Ok, great and thanks -- that's what I figured. I have the spacers and torque correct, so it ought to be something that a few rides will work out.
This is correct. I thought it was two 2.5mm on drive side but it is not.
