Product Overview
A modernly gorgeous friction thumb shifter from Dia-Compe that provides enough cable pull to shift through an 11 speed drivetrain. Perfect for putting a big cassette on bikes that otherwise have a classic aesthetic. This thumbie is also great for flat bar Gravel, MTB and Touring rigs, strong and sturdy, its built to last.
Dia-Compe's aluminium CNC 'thumbies' fit 22.2, 23.8 or 26.0mm bars. So they come with shims.
Power ratchet friction control (Non-Index type)
They work with 8-speed to 11-speed drive systems and most common derailleurs.
Will not work with SRAM mechs or Shimano Dyna-Sys, Shimano Shadow RD, Microshift Advent X. (We assume, as we haven't tried yet.)
Right Side Only.
