JRA Lark18 rim

£70.00 £30.00

REDUCED TO CLEAR, WE WILL NOT BE BUILDING THESE BUT YOU ARE WELCOME TO BUY THEM FOR YOUR OWN BUILDS. They are a slightly narrowerer width than our current rims and will be sold plain.

The Lark is a 18mm wide (23mm external width) rim with matt sandblasted finish and machined braking surface used on our road wheelsets. Designed for strength, light weight and reliability with 23mm deep semi-aero profile and asymmetric rear option for even spoke tensions. Suitable for road or cyclocross. The 8.5mm deep brake track allows for easy brake setup, while the high quality machining process leaves a smooth surface for consistent braking.
