PRODUCT DETAILS

ALL NEW Crupi Quad OS20 wheelsets featuring our NEW Rhythm OS20 rims built with Crupi Quad 36H hubs. The fastest Spring & Pawl Engagement System in BMX! The Quad Hub features 150 ratchet teeth which engage every 2.4 degrees so what you get it is a super fast engaging hub. (You won't know it's not instant engagement!)

We provide 4 cog spacers which allow you to position the cog where it provides the best possible chain alignment. Hubset comes with a 16t cog but is designed to work with any Shimano compatible cog. Laced with 14G spokes and alloy nipples to 36H Rhythm Section Pro rims, extruded from 6061-T6 aluminum for strength and durability. Includes 16T chromoly cog and rim tape.

You can choose from our 10mm or our 20mm front hub (depending on the fork you have as you must have a 20mm fork to use the 20mm hub). The 20mm front comes with extra spacers so the hub will work with carbon or chromoly forks!

Fixed independent leaf spring/pawl system acting simultaneously when engaged
Less resistance and less wear = a smoother rotating hub
NO Rider Weight Limit
Disc Rear requires a 6-Bolt Rotor
For Crupi frames, we recommend the Elevn Disc adapter kit with a 120mm rotor
Black wheels feature black rims and black spokes
Wheels with Red or Blue feature Black rims and spokes with Red or Blue hubs and nipples
We recommend a Park FR-5.2 Lock Ring tool to remove the cog
20mm hubs for use with a 20mm fork only!
Designed for use with an OS20 frame only. And even though OS20 forks are your best fit, most standard Pro 20" forks will work with the OS20 wheel so you don't need to buy a OS20-specific fork
