Long story short, being Sherlock a flexible cylinder, there are 3 main requirements:
- Internal diameter of the handlebar between 19 and 23 mm;
If it is wider than 23 mm, the device may “fall” inside the handlebar.
If it is tighter than 19 mm, the device may not enter at all.
- Extremity of the handlebar straight for at least 60 mm;
- Curvature median radius equal or greater than 50 mm.
It may happen than inner diameter decreases where the bar curves, due to metal bending. This makes the handlebar not compatible.
In case of carbon bars, check that internal surface of the bar is smooth, otherwise it may damage the device during installation.
*If the device is hard to insert or slips inside the handlebar, it means that your handlebar is not compatible. Never use a tool to force Sherlock in or to pull it out, it could break the device.
