I keep a matching freewheel on the opposite side my hub, I have to as my ACL is snapped and some days my knee doesn't go for track style skid stops. Previously I had a single PAUL E-lever and a front Dura Ace caliper but those were replaced with Syntace levers and Campy Mirage calipers. The up side of the parts swap was the Cinelli Tempo bar has the dual cut outs near the stem for internal cable routing, this is the first time I've been able to take advantage of the hidden housing.
