Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them.

Dura Ace Crank ?'s

Hey all, have a quick question, looking to upgrade the front crank to Dura Ace double, besides crank arm length and gearing ratios, what else should i be looking at? I assume one size does not fit all..... Is there BB issues, etc?...

Still learning.
Thanks for the help...

I have done this to my caad9 a few months ago.

You'll need the proper BB, if you already have another type of shimano crankset that is of the hollogram variety, then you can most likely re-use the existing BB. Otherwise you'll just need to buy a new BB (they are in the $ 49. range for Dura-Ace) so no big deal.

Other than that, you may or may not have to adjust your FD if you are going from regular size double to a compact double or vice-versa.

You'll just need a Hollowtech II compatible bottom bracket, which you may already have.

Of course, it's hard to know all the considerations without knowing which crank you are coming from. There's nothing complicated about Dura Ace. I would switch the BB, though -- it's an inexpensive upgrade.

If the bike also uses the M.O.st oversized bottom bracket system, you would have to have a shop remove the cranks and bottom bracket and install an adapter for standard English threaded bottom brackets.

English threads are vastly more common, and most mainstream bikes are English threaded (I think it's just the thread tpi difference). The common alternative is Italian, but I believe even the old Italian classics like Bianchi are English threaded now.

I don't know what a M.O.S.T. S-10 crank is. Google is not helping.

It's just bigger, fatter and pressfit.

f-sake, what's the world coming too? Why would anyone create such a monstrosity? If you saw the BB shell I was winning races on this season, you'd shudder.

A certain Italian sprinter seemed to like his new rig.
