Our 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 (aka barcon) shifters from Shimano, Campagnolo, SRAM and others. These shifters are readily available for 8, 9 and 10-speeds, and most have a friction option for everything else.

Admittedly, we weren't sure at first if these would be good idea or kind of gimmicky, but it was love at first test ride. The thumb shifting of old came back instantly and the bike shifted more precisely and smoothly than ever before. These feel much better in our opinion than trigger or twist shifters.

Road Thumbies fit handlebars with a 26.0 mm diameter. This is the thicker "bulge" section of the handlebar where the stem clamps on. The wider this section of your handlebars is, the more room you will have for the Thumbies.

Road Thumbies are designed to pair with Shimano bar end shifters. With the addition of our Silver Shifter Adapters, Road Thumbies will also work with the ratcheting Silver Shifters available from Rivendell. These shifters work just like the old Suntour Power Ratchet shifters, but better.

The bar end shifters themselves are not included with the Thumbies, sorry
