Comas Crank Bolts

Comas Crank Bolts

Description and materials
- Comas M15 crank bolts, specially designed for ISIS cranks.
- Used by Comas riders Eloi Palau, Sergi Llongueras, Vincent Hermance and Dani Comas himself.
- Ultralight, made from high quality 7075-T6 CNC aluminium alloy.
- Low-profile tapered head, with multiple recesses that help save weight.
- 18mm length and M15 thread, so they’re compatible with most ISIS bottom brackets.
- Sold as a pair, with a couple of 6061-T6 aluminium washers (one for each bolt) that must be used with the bolts.
- 8mm Allen hole-through head, for easier installation.
- Note: since these are aluminium bolts, they mustn’t be used to install the cranks. For that it’s recommended to use some steel bolts instead, then tighten the cranks, remove the steel bolts and install these aluminium bolts.
