Hi, thanks for looking in. I'm building up a bike to cope with the peak district. The shifters I want to use are shimano 8 speed 105 sti's ( drop bars ). I'm looking to put a 7 speed shimano cassette on the rear 32t or 36t. There are plenty of shimano mtb sgs ( long cage ) rear derailieurs but will they be compatible with my shifters. I would much appreciate your advice cheers Bill.
