7400 dura ace 112mm BB & 7410 double crankset, compatibility or not tight enough
I have a 7400 dura ace english BB, 112mm long. When I installed it with a 7410 double crankset,
the drive side seems to be sticking out a bit that the front derailluer isn't able to get to be big crank, even
after tightening the crank bolt. The non-drive side (left) is fine.
Is it a compatibility problem or the crank bolt isn't tight enough? I put some grease on the threads
already. The allen wrench doesn't have too much leverage. Don't know if that's the reason.
Please give me some tips.
The 7410 crankset uses a 102mm bottom bracket, so the 112 you're using would definitely be too long. Unfortunately, the only Shimano taper bottom bracket I can think of that comes in a 102 is the Dura Ace, so you're pretty much committed to spending some money.
yes, thanks. I just browsed through sheldonbrown.com. 7410 is a special breed, 103mm length. The
only compatible BB is 7410. 7400 crankset is 112-113mm, compatible with my 7400 BB.
So either get a 7410 BB or get a 7400 crankset. yikes!!
