[T-mag chain alignment conundrum]

Hi

The 68mm part of your bb measurement refers to the width of the shell

If you remove your bb from the frame and measure the actual axle part, it most likely will be 128mm (could even be labelled on the bb as a graphic or sticker I.e. 68x128mm)

If this is the case it may be worth looking at a narrower axle bb. For example 68mm x 122mm (narrower axle should bring your chain a little closer inbound and stop the rubbing on the stay. May even be able to go down as far as a 68mm x 113mm (or there abouts)

Check the bb is in the correct way too - should be labelled on the bb: L & R (left and right)

Hope this helps and you get the problem sorted anyway

Cheers

Barry

Thanks Barry. I tried out an old bb with a 113mm axle and it did the trick!

[T-mag chain alignment conundrum]

Hi guys,

I bought this bike a while back and I have only just started riding it regularly. Unfortunately the chain is rubbing a groove into the chain stay! I don't know a great deal about bike mechanics but it seems as if the bb axle is too long. Then again the bb states on it that it is for a 68mm shell. Can anybody enlighten me? Any help is greatly appreciated.

Thanks!

I've been riding trials about a month now and have developed some pretty impressive blisters. but it still hurt my palms like hell if i'm riding for more than 2 hours a day, any suggestions to reduce this problem?

Thanks, Daniel
