This latest production is designed to meet the needs of the cyclist who asks for the best in 3/32″ chainwheel and crank sets for 8 or 10 gears.
The two rings are cold forged and are held rigidly together in standard WILLIAMS practice. Teeth are specially designed to facilitate chain changing.
Cranks fitted are WILLIAMS Club racer.
Sizes available :-
Cranks | 6½” Racer non-G.C.C.
Rings | Outer 50T and 49T.

NOTE . . .
We recommend the use of WILLIAMS Club racer cranks ONLY for these rings, and no other should be used, owing to the risk of fouling the chain moving guide.
