Clamp Size
22.2mm or 26.0mm

22.2mm is equivalent to 7/8 inches, and is the diameter of most mountain bike handlebars. Many flat bars, risers and city bars have this diameter. It is measured at the end of the bar where grips and brake levers attach.

26.0mm is a common road handlebar size. It is measured in the center of the bars where the stem attaches.

Compatible Shifters
Shimano or SRAM

Shimano bar end shifters work well with our Shimano style Thumbies. Many of their indexed downtube shifters will work as well, so long as they mount to a flat, not curved, shifter boss.

Our SRAM style Thumbies will work with SRAM TT bar end shifters.

Silver Shifters from Rivendell can be used with our Shimano style Thumbies with the addition of our Silver Shifter Adapters.

Thumbie Shifter Mounts

Our Thumbies are the original upright handlebar mount. They easily transform bar end (aka barcon) shifters into thumb shifters. These shifters are not included, but are readily available in 8, 9 and 10-speed versions, and many have an option for friction-shifting.

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

Thumbies have a hinged clamp for an easy installation. Two sizes are available to fit handlebars with a diameter of 22.2mm or 26.0mm. On road bike bars this is the thicker section of the bar where the stem clamps on. On city and mountain bike bars the grip section is usually 22.2mm (7/8") in diameter.

The clamps on the 26.0 version is designed to work next to inline brake levers like our Cross Lever, while the 22.2 clamp is raised up to give clearance for hydraulic brake levers.

Two different kinds of Thumbies are available: Shimano or SRAM shifters.

The Shimano version, available in size 22.2mm only, has a shifter mounting boss that fits Shimano bar end shifter and some Shimanao downtube shifters.

The SRAM version, available in size 26.0mm only, has a mounting boss that is compatible with SRAM TT alloy bar end shifters, but will not work with R2C shifters.
