Crupi 24 x 1-3/8 28H CenterLock Wheelset
Description
The Crupi 24 x 1-3/8 28H CenterLock Wheelset is an all-new 2026 Expert Cruiser wheelset built specifically for Expert and Expert XL Cruiser BMX frames. At its heart is Crupi's Quad CenterLock hubset, featuring a Spring and Pawl engagement system with 150 ratchet teeth that engage every 2.4 degrees - making it one of the fastest-engaging hubs in BMX racing today. The rear hub ships with 6mm Allen screws, eliminating the need for tensioner spacers and ensuring clean, precise fitment into frames with enclosed dropouts.
Laced with 15G spokes and alloy nipples to Crupi's race-tested 520mm Rhythm Section 28H rims, this wheelset delivers exceptional stiffness and reliability on the track. Four included cog spacers let you dial in perfect chain alignment, and the CenterLock hub design means you can upgrade to disc brakes down the road with the separately sold CenterLock ISO Converter or Crupi Disc Brake Adapter Kit. Whether you're racing at the local track or competing at a national event, these wheels are engineered for performance-focused riders who demand the best.

FAQ
What frames are these wheels compatible with?
These wheels are designed exclusively for Expert and Expert XL Cruiser BMX frames. They are not intended for use on other frame sizes or styles, so be sure to confirm your frame size before ordering.
What is the CenterLock system and how does the disc brake conversion work?
The CenterLock system is Crupi's proprietary hub interface that allows the rear hub to be converted for use with a disc brake rotor. To convert, you'll need the CenterLock ISO Converter (sold separately) or the Crupi Disc Brake Adapter Kit (also sold separately). The wheelset ships ready for V-Brake or disc use once the adapter is installed.
Do these wheels come with tubes?
No, tubes are not included. These wheels require Presta valve tubes, which are sold separately. Make sure to pick up a set of Presta tubes before riding.
Can I change the cog size?
Yes - the wheelset includes a 16T aluminum cog at no extra charge, but you can select an alternate cog size (13t, 14t, 15t, 17t, or 18t) for an additional fee at the time of purchase. Four cog spacers are also included to help you achieve the best possible chain alignment.
Why do the colored versions (Red and Blue) have black rims and spokes?
For the 24 x 1-3/8" size, the rims are only available in black. The Red and Blue colorway options feature black rims and spokes with colored hubs and nipples to match your preference. This keeps the build strong and consistent while still offering a custom look.
Is assembly required?
These wheels come pre-built and laced - they arrive as a complete front and rear wheelset ready to install on your compatible Expert or Expert XL Cruiser frame. No wheel building is required on your end.
