[AD-1]

Very little use with Scottoiler.
New goes for £70.
Looking for £50 all in.

High-strength alloy steel teeth for extra long life
Aluminium centre section reduces the unsprung mass
Permanently joined together with high-tensile rivets
At least three times longer service life than any other aluminium rear sprockets
50% lighter than conventional steel sprockets

Will check how many teeth i have on my sprocket later and get back to you if that's ok ...
