Title: Sprocket troubles
Post by: guest1406 on July 05, 2013, 10:23:38 AM

Hi all,

As ive done an engine swap on my bike the sprockets and sprocket size are all different of course. I was wondering (and hopeing!) you could get a solid sprocket made up for my new engine so that I can drill the fixings myself?

Try B&C Express (http://www.bandcexpress.co.uk/sprockets/special-fittings.html) - they can make up special sprockets to your size/pitch/ hole spacing.

Cheers Steve. They call them blank sprockets, thats why I couldnt find them.

Ive now got my blank sprocket but now need it fitting to he original hub. Theres no way in hell i could produce the exact measurements so obviously need skiled engineers to do it.

Anyone know of where it could be done?

JT sprockets website provides a lot of dimensional information relating to spigot sizes, PCD, hole sizes etc. A check with a steel rule should confirm which version you have.

Incidentally, I dealt with B&C express recently and found them very helpful and efficient.
