inner ring clearance

[gregs656]

I'd really like a bit more clearance on the inner ring on my bike. I took the cranks off today to clean and, although I check frequently, the inner ring has definitely rubbed up against the frame at some point.

Can you buy spacers?

You could buy a spacer for the bb to shift it over a couple of mm

Do they sit inside the cups? Sounds like what I need.

Take out fixed cup, put over spacer and screw fixed cup back in again, ...........the free cup will then screw in the corresponding extra so there's not a lot to play with. !!

We used to use very thin spacers if the fixed cup had a habit of coming loose

Ah I see. Well any gain would be handy.

Of course ideally you'd just fit a slightly longer bb.

 

[gregs656]

I'd be open to that. There's a chorus one on there at the moment. To e honest it didn't occur to me that they would be available in different lengths.

Oh right! Well that's the best method to solve your problem. What crankset have you got fitted?

 

[gregs656]

Athena, I tried a pair of chorus (I think) cranks today and they were even worse. Ill have to check what length I've got. Might as well do it properly.

Thanks for taking the time. You dont think about these things until you run into a problem.

Is it a sealed unit or adjustable cups?
