The fastest Spring & Pawl Engagement System in BMX!The Quad Hub features 150 ratchet teethwhich 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 w/ a 16t cog but is designed to work w/ any Shimano compatible cog. Laced w/ 14G spokes and alloy nipples to 36H Rhythm Section Pro rims, extruded from 6061-T6 aluminum for strength & durability. Includes 16T chromoly cog & 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 w/ extra spacers so the hub will work w/ carbon or chromoly forks!
