Dura Ace 9000 cranks

aiwa_yamaha

I want to sell my FSA SLK cranks and get the 11 speed Dura Ace 9000 crankset. Will this work on my Specialized Tarmac Comp 2012? I have a 10 speed Ultegra set up but would assume cranks would still work.

Should be fine.

I was just worried as it clearly states in the selling description 11 speed Dura Ace 9000 crankset

As above, I don't see any issue

It's fine but I'd suggest using the 11 speed chain as well.

Sounds good to me. Also my bike runs a BB30 system. Would i be able to swap to the integrated Shimano Hollowtech II BB?

Thanks Grill. I shall buy the Shimano Ultegra 6800 Chain.

Grill

The 9000 chain is so much nicer...

I would match the chain to the cassette rather than the chainring... if you have a 10 speed cassette, use a 10 speed chain, which is probably also cheaper

If i buy the 6800 11 cassette does that mean i can switch to 11 speed?

Yes as long as you also buy the shifters, rear mech, and have an 11spd compatible freehub.

I definitely wouldn't bother changing the chain. More likely to do harm than good.

Grill

The opposite is more likely to be the case.
