Pompino - Winter Beast

I'm not convinced by the goldfinger levers either, never really found them comfortable or they gave enough stopping power, some proper flat-bar canti levers might not look a bit bulkier but I'm pretty sure they'd be cheaper and work better.

The ones you want are these Tektro fl750

They work with road calipers and cantis. They're fairly light. Comfortable to use and well priced.
