SHIMANO Thumbies

Do you miss thumb shifters? Converting a drop bar bike to flat bars? These easily transform bar-end (aka barcon or TT) shifters into thumb shifters. The shifters are not included, but are readily available in 8 through 11-speed versions, and many have an option for friction-shifting. Heck, these will work on any indexed Shimano bar-end shifter going all the way back to 6 speed!

$60.00 – $192.00

  • Clamp Size
    22.2mm and 31.8mm ↓

    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.

    31.8
    31.8mm is the clamp diameter of most handle bars and this size is designed for that section of a drop bar. The shifters are mounted on either side of the stem and are very easy and convenient to operate.

  • Compatible Shifters
    Shimano ↓

    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.

Product Story

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

Thumbies have a hinged clamp for an easy installation and fit handlebars with a diameter of 22.2mm or 31.8mm. The 22.2 models fit mountain bike handlebars and the 31.8 mount to the stem clamp area of a drop bar. The clamp is raised up to give clearance for hydraulic brake levers.

They have a shifter mounting boss that fits Shimano bar end shifters and most Shimano downtube shifters, so long as they mount to a flat, not curved, shifter boss.
