Hello everyone!

I am getting parts to upgrade my drive chain, and was on the market for a compact crankset. nashbar so happen to have a big sale on some 11-speed crankset, and i was wondering if I could use that. The rest of the gears would be for a 2x10.

Actually, there is a SRAM Force 22 crankset for $130, but it says compatible with yaw derailure only. would this not work with the regular (non yaw) derailleur (I was given an old RD-7700).

much thanks in advance!

Any 11s crank will work fine with an otherwise 10s drivetrain. I'd recommend the non sram crank, it would work w/o a 'yaw' fder but there are better BBs and chainrings out there. What's the crank type from Nashbar?

Thanks for the info!
Mostly because of price, I was looking at this Force 22 w/ BB30.

I thought BB30 was a good bottom bracket, no? Admittedly the Press Fit BB will not work for my bike...

Thanks again!

What type of bottom bracket does your frame have?

I think it is a Shimano BB-5500 with English thread (68mm).
Right now I have a 3x9 drivetrain on it, but I was hoping to get the parts to upgrade it to a 2x10, without breaking the piggy bank :)

if its a threaded BB you cannot install a BB30 bracket or PF30 bracket, you need to find a english threaded bb and a crankset that is compatible with that.

This is not quite correct. The Force22 crankset will work with his threaded frame if he gets a Rotor BSA30 BB. http://www.rotorbikeusa.com/products/bsa_bottom_bracket.html

Kind of expensive, though...

I am sure there are other adapters as well to make this work. Think there is a bsa adapter for hollowgrams too but that is just silly.

I have a hollowgram if he is interested. :bike:

There's no practical way to use Hollowgrams with a BSA BB shell due to the short spindle length.

The Force22 BB30 spindle is wider, like the Rotor 3D+, so there is no issue with spindle length.

good info on all the possible options and pitfalls, thx folks! :beer:


Another friend found this interesting articles on yaw vs non-yaw compatibility:

http://velonews.competitor.com/2012/03/news/it-works-we-test-sram-red-backwards-compatibility_209270

it doesn't cover 10 vs 11 speed drivetrain, but I don't think 11 sp shifter would work with 10 speed casette, cuz the 11 speed is wider than the 10 speed. hopefully some gurus in the list can confirm this.
