Comments about Interloc Racing Design (IRD) IRD Power Ratchet Thumb Shifters:
I put these on my around town commuter with a 3x9 drivetrain and have absolutely no complaints. These shifters have a classic ratcheting friction shifting feel that is reminiscent of vintage ratcheting Suntour bar-end and thumb shifters. Friction shifting means simple setup and adjustment, literally just setting your derailleur limit screws, and you're good to go. The hinged clamp attachment is convenient and the silver finish adds a touch of class to any bike, particularly vintage builds.
