Paul Mountain Thumbies Bar End Gear Lever Shifter Mounts - 31.8 mm Band On - Shimano Version - Black

Paul "Thumbies" are the original upright handlebar mount for bar end shifters. They do not include the shifter but are designed to be used with indexed bar end shifters from Shimano, Campagnolo, SRAM & others, this version is for use with Shimano shifters only. The shifters are readily available for 8, 9 & 10 speeds, & most have a friction option for everything else.

There are three versions available to pair with Shimano bar end, Campagnolo bar end of SRAM TT shifters. Each company has their own shifter boss fitting and they are incompatible with one another.

Mountain Thumbies fit standard mountain bike handlebars but will work with almost anything that has a 31.8 mm diameter. The shifter boss is raised from the bar to give clearance for bulky two-bolt brake levers & the hinged clamp makes installation easy.
