Paul what make rear sprocket carrier have you got, I have a few sprockets around that I use for changing the gearing when racing, I could see what I have got, most are a 520 pitch but some are 525. I will look in the moring and if I have a 36 or 37 you could borrow it while you see about sorting the chain. I have chain splitters and riviters as well and I usually get my soft links from what was M&Ps next door to Fox's diner. If I have a sprocket it may be worth you coming up on the monster or in the car tomorrow. Kev |
