Stronglight TT Aero Timetrial Chainring

53T, BCD 130mm to suit Shimano / FSA etc. cranks (i.e. NOT for Campagnolo 135mm, or compact cranks 110mm)

Lightweight, Ergal 7075 alloy chainrings from Stronglight. Designed primarily for track and TT use, but machined out on the inside to keep the weight down so would also be a nice stiff upgrade for a regular road chainring.

9/10 speed chainring (may suit 11 speed, being honest can't confirm)
130mm BCD 53t
CNC construction
Solid aero ring design
