The TIMBER Bolt-On is identical to the original model, except it features a tight, durable mount that won't spin, shake or rattle on your bars. Similar to a GPS or Garmin mount, the flexible nylon band tightens to your bars with a 5mm hex bolt. The band itself is 31.8 mm diameter, the same as the wider part of your bars near the stem. It also includes a flexible 22.2 mm shim, for mounting your bell securely near your grips, closer to your hands. (For oversize and DH bars, you will want to use the shim and mount near the grips.)

​

Installation is easy. There is no need to remove the grips, brakes, etc. Just flex the clamp open and slide onto your bar.
