This is a great tool for lubing your bike chain! It puts the chain lube on evenly across the rollers and where the o-rings are and stops any over spray getting on your wheel and tyre. I'm very impressed with it and would highly recommend.
C6 fixing hole centres 63 x 30. C3 fixing hole centres 61 x 29.
I Modified to fit my C3 By carefully slotting the fixing holes. The actual distance the hole centres move is only 1.1mm on the diagonal. Works a treat. Great product!
