I just finished another batch of six of the Cinelli-Windsor seatpost binder bolts to offer to list members who may need them. These are 40mm long stainless hex head bolts with a nut that is hex on one end and round on the other. Bolts are handmade by me and are metric M7 thread. They will fit older Cinelli and Windsor bikes. Photo and price on request, contact me off list. Thanks.
