New Crank Selection
« on: December 14, 2008, 06:51:56 PM »
I need to get a new crank set. Any suggestions? Anything I should stay away from? My current one is a Bontrager Race GXP 44/32/22 and the crank arm keep coming loose.

I'd say get the Shimano crankset that looks the prettiest or is in your price range.  IMHO, Shimano just makes the best cranks out there.

I recently bought a FSA V-Drive at Aj's. About $180 with my Swamp discount. No problems yet and was easy as hell to install. Reason for replacement......broken (in half) drive side crank arm on my XTR's. I almost cried. Replacement crank arm cost more than a new complete crank set.

I second the motion for the Shimano cranks, you can go XT for $200.

Have you tried different crank bolts? Unless you're just itching for another upgrade... +1 for Shimano XT

According to reviews on MTBR.com this is a common problem that will eventually render the crank unusable. Any chance of warranty? I'd certainly call Bontrager anyway since your not the only one.

If not I'd probably try a new crank arm bolt with super strength Red locktite. Clean everything off with brake cleaner first. If that doesn't work I think your ready for that upgrade. If you do any jumps at all I'd avoid Shimano's hollow crank arms. Ask me how I know.

chainreaction has the xt for $155.  I have ordered a few things from them and have had no problems but YMMV.

CR also has the XTR in stock for $330 shipped, I got one for $280 a few weeks back. Check their site often as their pricing reflects market kind of like the gasoline market ;D

I've been running Shimano XT (older Octalink and current outboard bearing model) and Saint cranks on my bikes for a while know and haven't had any issues and my tires leave the ground on occasion.  I also know many DH riders use XTR cranks for their race rigs.

Where would I get replacement crank bolts? I've thought about having a replacement made in the shop where I work.

I'm not exactly sure what kind of crank bolts you need (not familiar with your particular crankset), but something from here - http://www.jensonusa.com/store/sub/131-Cranksets.aspx?s=1259 - should work.

Order one of these too - http://www.parktool.com/products/detail.asp?cat=25&item=BBT-9

It is the tool for installing/removing the crankset.  With this and the directions here - http://www.parktool.com/repair/readhowto.asp?id=122 - you can install the cranks yourself in like 15 minutes.

You must be talking about the super old XTR's. I had the XTR series two's that have hollow crank arms. These are the shinny gun metal colored cranks that the finish wears off of if you look at them wrong. I've also noticed DH guys running the old XTR's.
I still have the left crank arm with new hardware, BB (needs new phil wood bearings), and the chainrings. Wonder if someone could put any of it to good use?
