SRAM Thumbies

Miss thumb shifters? Converting a drop bar bike to flat bars? These easily transform bar-end (aka “barcon” or “TT”) SRAM shifters into thumb-shifters. The shifters are not included, but are readily available in 10 and 11-speed versions. These mounts are not compatible with “R2C” (Return To Center) SRAM shifters. Precision machined with pride in Chico, California.

$60.00 – $173.50

Product Story

Thumbies bring back the thumb shifting of old, and we think they make shifting more precise and smoother. These feel much better in our opinion than trigger or twist shifters.

Thumbies have a hinged clamp for easy installation that fit all flat bars, MTB risers and city bars with a diameter of 22.2mm (equivalent to 7/8 inches). Diameter is measured at the end of the bar where grips and brake levers attach.
The clamp is raised up to give clearance for hydraulic brake levers and has a shifter mounting boss that fits SRAM 10/11-Speed Bar-End shifters. All necessary mounting hardware is included.

Chico is a fun and easy city to bike commute in. I Chico is a fun and easy city to bike commute in. It’s totally flat, there are plenty of bike lanes and neighborhood routes with little to no traffic, it doesn’t take more than half an hour to get from the farthest edge to the opposite edge of town, and in our case here at PAUL World Headquarters, there’s even an old railway converted to a bike path leading right up to our back gate. 🚂🚴Congratulations to @myles56k on winning our Ride2Work Challenge for the last two years! He might have some competition from @jxrad this year though…should we start taking bets?
