Crupi 24 x 1-1/8 28H CenterLock Wheelset
Description
The Crupi 24 x 1-1/8 28H CenterLock Wheelset is an all-new 2026 BMX race wheelset built specifically for Mini, Junior, and Expert Cruiser frames. Centered around Crupi's innovative Quad CenterLock hubset, these wheels deliver one of the fastest engagement systems in BMX - with 150 ratchet teeth engaging every 2.4 degrees, the Spring and Pawl system is so responsive it practically feels instant. The 28H rear hub features 6mm Allen screws that eliminate the need for tensioner spacers, making installation clean and straightforward in frames with enclosed dropouts.
Laced with 15G spokes and alloy nipples to Crupi's race-tested 520mm Rhythm Section rims, this wheelset is a proven performer on the track. Four included cog spacers let you dial in perfect chain alignment for your specific setup, and the CenterLock hub design means you can upgrade to disc brakes down the road with the separately available CenterLock ISO Converter or Disc Brake Adapter kit.

FAQ
What frames are these wheels compatible with?
The Crupi 24 x 1-1/8 28H CenterLock Wheelset is designed to fit Mini, Junior, and Expert Cruiser BMX frames only. It is not intended for standard 20" BMX frames. Always verify your frame's dropout spacing and wheel size requirements before purchasing.
Can I add disc brakes to these wheels?
Yes - that's one of the standout features of the CenterLock hub design. You can convert to disc brakes by adding the Crupi Disc Brake Adapter Kit (sold separately) or the CenterLock ISO Converter (also sold separately). The hub is compatible with both Disc and V-Brakes right out of the box.
Do I need to buy tubes separately?
Yes. These wheels require Presta valve tubes, which are not included. Make sure to pick up the correct Presta tubes sized for 24" wheels when ordering.
Can I change the cog size?
Absolutely. The wheelset comes standard with a 16T aluminum cog, but you can select an alternate size (13t, 14t, 15t, 17t, or 18t) for an additional charge when ordering. The included cog spacers also allow you to position any cog for the best possible chain alignment with your frame.
What is the Spring and Pawl engagement system, and why does it matter for racing?
The Spring and Pawl engagement system is the mechanism inside the rear hub that determines how quickly power transfers from your pedals to the wheel when you start pedaling. Crupi's Quad CenterLock hub uses 150 ratchet teeth engaging every 2.4 degrees, making it one of the fastest-engaging systems in BMX. In racing, a faster engagement means less dead time between when you push the pedal and when the bike accelerates - which can make a real difference off the starting gate and out of corners.
Do I need tensioner spacers with this wheelset?
No - the new 28H rear hub features 6mm Allen screws that eliminate the need for tensioner spacers. This also makes the wheelset compatible with enclosed dropout frames, providing a cleaner and more secure fit.
