  • Compatible with any standard road, mtb, and city handlebars (22.2 and 23.8mm grip area)
  • Hinged design so you don't need to remove any components or accessories for installation
  • Integrated barrel adjustor to dial in cable tension on the fly

Amazing little mounts! Paired these wthe diacompe downtube shifters and it’s a winning combo!


Great product. One little issue there are no instructions. However not all that difficult to figure out. Bought to change a drop bar to a commuter bar and mount the shifters on the bar instead of the drop tube and be able to retain the original Shimano 105 friction shifters. Still instructions would be nice.

Worked great!

Had vintage Suntour downtube shifters. Added 5mm aluminum axle spacer between each lever and mount. Made for perfect alignment and works great!

Very Nice Product!

These are the perfect solution for shifting with my favorite cockpit setup. To get them to work with Shimano L422 ratcheting downtube shifters I did have to steal a part from some Shimano bar end shifters, and also swap / invert left and right shifters, but the result is optimal.
