All new for 2026, this wheelset is centered around Crupi's innovative Quad CenterLock hubset - featuring 150 ratchet teeth that engage every 2.4 degrees, delivering a spring and pawl engagement so fast you won't believe it isn't instant. Laced with 15G spokes and alloy nipples to race-tested 406mm Rhythm Section 28H rims, every component is chosen for race-day performance and long-term durability.\n\u003c\/p\u003e\n\u003cp\u003e\n  One of the standout upgrades on this wheelset is the rear hub's 6mm Allen screws, which eliminate the need for tensioner spacers and allow clean, flush fitment into frames with enclosed dropouts. Four included cog spacers let you dial in perfect chain alignment no matter your setup. The CenterLock design also gives you a clear upgrade path - add a Crupi Disc Brake Adapter kit and this hub converts to disc brake use, making these wheels a smart long-term investment for any serious BMX racer.\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuad CenterLock Hubset:\u003c\/strong\u003e Features 150 ratchet teeth engaging every 2.4 degrees - the fastest Spring \u0026amp; Pawl engagement system in BMX racing.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e406mm Rhythm Section 28H Rims:\u003c\/strong\u003e Race-tested double-wall rims laced with 15G spokes and alloy nipples for a stiff, reliable wheel build.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Brake Convertible:\u003c\/strong\u003e Compatible with both Disc and V-Brakes; add the Crupi Disc Brake Adapter Kit (sold separately) to convert to disc use.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e6mm Allen Rear Hub Screws:\u003c\/strong\u003e Eliminates tensioner spacers for a clean fit in frames with enclosed dropouts - no extra hardware needed.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e4 Cog Spacers Included:\u003c\/strong\u003e Allows precise cog positioning for optimal chain alignment across different frame setups.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e16T Aluminum Cog Included:\u003c\/strong\u003e Lightweight alloy cog included as standard; upgrade cog sizes (13t-18t) available at additional cost.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight: 2lbs 15oz:\u003c\/strong\u003e Competitive race weight, keeping your setup light and fast on the track.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecommended Rider Weight Limit: 140lbs:\u003c\/strong\u003e Engineered specifically for lighter, younger Expert-class racers.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmerican Valve Compatible:\u003c\/strong\u003e Rims require American valve tubes for inflation.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePro Frame Compatibility:\u003c\/strong\u003e Designed to fit Pro frames; works on Expert \u0026amp; Expert 2X frames when used with brake extenders.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eCog Size Options \u0026amp; Which to Choose\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e16T (included, no extra cost):\u003c\/strong\u003e The standard race cog included with every wheelset - a popular all-around choice that suits most Expert-class track configurations and gearing setups.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e13T (+$10):\u003c\/strong\u003e A smaller cog for riders who prefer a taller gear ratio, maximizing top-end speed on longer, faster tracks.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e14T (+$10):\u003c\/strong\u003e A step up from 13T, offering a strong balance of acceleration and top speed - great for tracks with long straights.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e15T (+$10):\u003c\/strong\u003e A slightly lower gear ratio than stock, offering a touch more snap out of the gate - ideal for shorter, more technical tracks.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e17T (+$10):\u003c\/strong\u003e Lower gearing for stronger acceleration off the start - best suited for riders with smaller chainrings or tracks with tight turns.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e18T (+$10):\u003c\/strong\u003e The lowest ratio available, delivering maximum snap and low-speed torque - a great pick for younger or developing riders who benefit from easier pedaling.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eWhat's Included\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eFront and rear 20\" x 1.50 28H Rhythm Section wheels (pre-built)\u003c\/li\u003e\n  \u003cli\u003eCrupi Quad CenterLock 28H hubset\u003c\/li\u003e\n  \u003cli\u003e16T aluminum cog (upgrade sizes available)\u003c\/li\u003e\n  \u003cli\u003e4 cog spacers\u003c\/li\u003e\n  \u003cli\u003eRim tape\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eWhy You'll Love It\u003c\/h2\u003e\n\u003cp\u003e\n  Crupi has been building race-proven BMX components for decades, and the 2026 CenterLock Wheelset represents the next evolution in their lineup.

So on the Black\/Red and Black\/Blue colorway options, the rims and spokes remain black while the hubs and nipples are colored.
