The mounting bar where the caliper bolt is attached sits higher on the seatstays thus providing more clearance for mudguards and/or larger tyres.do you know what size tyres could fit the Synapse? ..... Just wondering if they have the long drop brakes because of the frame difference or to accomodate wider wheels.
I've attached a pic showing the rear caliper over the Continental Gatorskin 28's and Crud Roadracer Mk2's I've fitted. I did look at more substantial guards but liked the stealth look of the Crud's and they perform brilliantly with the extra space offered by the Synapse.
