Brake Levers
Used road brake levers are almost always integrated shift-brake units — Shimano calls them STI, SRAM uses DoubleTap and Campagnolo uses Ergopower — and they are the single most expensive component in a groupset. Hood shape, reach adjustment, lever throw and ergonomics vary significantly between brands, so listings here range from full STI sets to the dedicated levers used on time-trial and touring builds.
STI, DoubleTap or Ergopower?
Modern road brake levers integrate shifting, so you will not find separate brake levers on a standard road brake setup. Shimano STI levers use a combined brake lever (push inward to shift down) and a smaller inner lever (shift up). SRAM DoubleTap uses a single lever with two movements — a short push to shift up, a long push to shift down. Campagnolo Ergopower uses a thumb lever behind the brake lever for downshifts and a finger lever for upshifts. Each system has loyal users, and ergonomic preference is genuinely personal.
Which levers suit smaller hands?
Shimano hoods are the most compact and suit smaller hands; SRAM hoods are bulkier, especially on hydraulic AXS levers, which some riders with small hands find too large; Campagnolo hoods are intermediate. Most modern levers offer reach adjustment via a screw or shim that moves the lever closer to or further from the bar, and the Shimano R7000, R8000 and R9100 series offer the best reach range. Test hood comfort on a long ride before committing — you spend more time on the hoods than anywhere else.
What levers do TT and touring bikes use?
For time-trial bikes, dedicated brake levers mount on the aero bars rather than being built into the shifters. Bar-end and inline levers serve specific purposes on touring and cyclocross setups.
What should I check buying used levers?
STI levers are precision mechanisms, so check both shift directions work cleanly through all gears. On hydraulic levers — the ones running hoses rather than cables — squeeze the brake: it should feel firm, not spongy. Check the hood rubber for tears and hardening (replacement hoods cost £15-30) and inspect the lever pivot for play. Crashed levers often have bent or cracked internals that are not visible, so shift through every gear before buying, and note that Campagnolo Ergopower levers from the 2000s era can develop a worn ratchet mechanism.
Are used Di2, AXS and EPS levers safe to buy?
Electronic levers need verifying against their own system: check they pair correctly and shift reliably on battery before you commit.
