bb30 crank with hollowtech 2 bb?

markynulty

Hi. I have just got a new frame with a dura ace crankset with 130bcd. Cant put my 52/36 Q rings on it as they are 110bcd. I am therefore looking for a new crank. I have seen some fsa slk light knocking around for reasonable prices. Only problem is that they state they are for bb30. What would I need to do to run them on a hollowtech 2 bb?

nicklouse

you cant. look at different cranks.

markynulty

Ah crap. Thanks for response though.

Any suggestions? I know most of the shimano cranks accept them on opc3 only, so that rules them out.

What about the megaexo bb cranksets? Are they compatible with hollowtech 2?

nicklouse

yes their BBs will fit the frame.

and most of their cranks can work fin with the HT2 BBs.

Thanks, will look into some of those sets and come back before I buy.

nicklouse

look at the cranks and BB together to save on probs.

Right I have found these three which all seem to be suitable. Any ideas which is the better one to go for?

Like I said earlier I will not be using the rings, just the arms with my q rings. I quite fancy option 3, the slk light unless anyone knows better?

Thanks.

Other option are the rotor 3D cranks. They are two ton though... Anyone experience with these?

Yes, Rotor 3D cranks are the only 30mm spindle cranks that will work with a regular 68mm BB shell because the bearings sit outboard, not inboard like BB30. Alternatively, any 24mm spindle crank like Hollowtech 2, MegaExo, GXP etc will all work.

Cheers guys, I have ordered a set of rotor 3d cranks today from velotech.
