Road Front Derailleurs come in electronic and mechanical format. They are also available in ‘band on’ (The mech clamps directly around the seat tube) and ‘braze on’ (The mech is bolted onto a small bracket brazed or riveted to the frame). ‘Braze on’ front derailleurs can be used on a ‘band on’ frame using an adapter. Make sure the band or adapter is the correct diameter for your seat tube. Merlin stock front derailleurs from Shimano, Campagnolo and Sram.
