Cratus 1x 130BCD 5 Bolt Chainrings
PLEASE NOTE THE IMAGES SHOW A 110BCD 4 BOLT CHAINRING. THE 130BCD 5 BOLT HAS A CIRCULAR CUT OUT.
You'll no doubt have seen alloy chainrings, carbon-fibre chainrings and probably even coated chainrings, all looking to reduce surface friction and therefore increase drivetrain efficiency. We have gone back to the base materials used to produce a carbon-fibre chainring and researched how we can improve these to reduce friction, increase durability and make you faster. Working alongside a British carbon-fibre cloth manufacturer, we have produced our own material infused with a nano-scale friction modifier.
Our own inhouse testing throughout the development process showed an optimal level of friction modifier, resulting in an increase of 0.5% in drivetrain efficiency when compared with a standard carbon-fibre chainring.
The track version of this ultra-high performing chainring was recently utilised by our very own Dan Bigham when setting the new British Individual Pursuit National Record and picking up the gold medal with a 4.05.274, becoming the third fastest pursuiter in history!
