Product Details

This is the Praxis Works Single Speed 104mm BCD Mountain Bike Chainring. Praxis have brought out these new single rings for people who dislike front derailleurs and just turn their cranks until smoke comes out their knee caps. They begin with a 4mm 7075-T6 blank of Aluminium and then stamp and machine the rings to perfection. With ring tooth counts from 32T all the way up to 38T, Praxis have you covered. Don't be afraid. Rip that front derailleur off your bike and see how running a single up front can free your soul.

Every single Praxis chainring is created using their proprietary forging technique, allowing Praxis to delicately manipulate the ring shape and tooth profile more than ever before. With Praxis' ''One-Shot'' forging, they are able to increase the amount of shifting features on a chainring above that of which normal CNC manufacturing would allow. The process also creates a harder and tougher surface for durability. Individual tooth profiles, alternating tooth angles, timed ramps and tactically placed shift elevators are all jam packed onto a Praxis ring. Translation: All of these small aggregate features add up to the most durable and consistent shifting rings ever produced for cyclists.

Extra Features Forging refines that grain structure and improves the physical properties of the 7075 T6 Aluminium, Harder and tougher than CNC'd rings
