e*spec Direct Mount Aluminium
Our new direct mount e*spec chainrings use our new M3 narrow-wide tooth profile, which reduces weight without sacrificing chain-retention. In making our SL and UL chainrings lighter and more beautiful than their predecessors, we adapted a similar design to work with Bosch, Brose, and Shimano motor configurations.

Fits - 52mm or 53mm (Boost chainline)
Compatibility - Bosch™, Brose™, Shimano™ & Fazua™
Options - 32t (Shimano only), 34t, 36t, 38t
