i was wanted to upgrade my front derailer (it is a 105 right now) to ultegra to complete my ultegra group. when i went online to buy one, i wan confused when i had the choice of braze on and clamp on derailer. i assume mine is a braze on because there is no metal band near the bottle cages but was wondering if switching a braze on derailer was as easy as unscrewing the old one and screwing in the new one. thanks
