Timber Bolt-On Bike Bell
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 wide part of your bars near the stem. It includes a flexible 22.2 mm shim, for mounting your bell securely near your grips, closer to your hands.
Timber has also improved the life of the index mechanism, and beefed up the strength of the internal clapper cable.
