So I need to send my Red shifters in for a warranty replacement which means I won't have them for a little bit. I just bought a set of Cane Creek brake levers so that I can at least ride in the meantime (53/12 or 39/12). Any other suggestions on how to ride without shifters or convert my bike into a decent SS for a bit? If I took the rear derailleur out completely could I buy a new chain and then install it so I could use a different gear combination??
