On this wheelset, Crupi's Quad CenterLock hub also delivers an exceptionally fast 150-tooth Spring \u0026amp; Pawl engagement system, engaging every 2.4 degrees.

Most standard BMX race forks use a 3\/8\" (10mm) axle. Some higher-end or specific race forks use a 20mm thru axle for added stiffness. If you are unsure, check your fork's specifications or the manufacturer's website before ordering, as the axle size cannot be changed after the wheel is built.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eCan I change the cog size from the included 16T?\u003c\/summary\u003e\n    \u003cp class=\"faq-content\"\u003eYes - at checkout you can select an alternate cog size including 13T, 14T, 15T, 17T, or 18T for an additional charge.
