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 – $192.00

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.

Should we bring back #FixtureFriday ? Before you c Should we bring back #FixtureFriday ? Before you can make all the parts, you have to make all the fixtures, and these aren’t something you can buy off a shelf! All of our production and assembly fixtures are one-offs made by Paul or Patrick or Jacob in the manual machine shop (although Jacob just made our first ever 3D printed fixtures, but that’s a story for a different Friday 😉). 
  This fixture is for pressing the little sealed cartridge-bearings into our Canti and Love levers. Once mounted in an arbor press, a little magnet holds the bearing until you press-fit it into the lever blade with a pull on the arbor press. In theory these bearings could be replaced down the line, but we haven’t had to do it yet. Thank you for attending our Ted Talk, happy Friday! ✌️

Sure, you might see us goofing off and getting weird at bike events, but when we get back to work in the machine shop, we take our work VERY serious!
