With a 45mm rim depth and an exceptionally wide 28mm inner width, this wheel strikes a rare balance between aerodynamic efficiency and versatile tire compatibility, accommodating everything from 28C road tires up to 57mm gravel and even mountain tires. The wide profile reduces air turbulence at the tire-rim transition for optimized aero performance while increasing tire volume for improved rider comfort and control on rough or poorly maintained surfaces.\n\u003c\/p\u003e\n\u003cp\u003e\n  Built from Toray T700 and T800 premium carbon fiber, the GP45 Carbon weighs in at just 400g per rim and meets 2.25x the impact strength of UCI standards at 40 joules - giving you confidence on the most demanding terrain. Whether you're lining up for a gravel race, grinding out a long touring ride, or pushing through crosswinds on a mountain stage, the GP45 Carbon is built to handle everything you throw at it.\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e45mm Rim Depth:\u003c\/strong\u003e Versatile depth that balances aerodynamic performance and crosswind stability across road, gravel, and singletrack terrain.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e28mm Inner Width \/ 35.7mm External Width:\u003c\/strong\u003e Accommodates tires from 28C road tires up to 57mm gravel and mountain tires, optimizing tire profile and aero transition.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToray T700 \u0026amp; T800 Premium Carbon Fiber:\u003c\/strong\u003e High-modulus carbon construction delivers a lightweight, stiff, and durable rim for performance riding.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e400g Rim Weight:\u003c\/strong\u003e Exceptionally light for a 45mm deep carbon rim, keeping rotational weight low for better climbing and acceleration.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.25x UCI Impact Strength Standard (40J):\u003c\/strong\u003e Built to handle real-world impacts well beyond minimum safety certifications.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTubeless Ready with Semi-Hooked Bead:\u003c\/strong\u003e Full tubeless compatibility for lower tire pressures, improved traction, and reduced flat risk.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e24-Spoke \/ 2-Cross Pattern with Proprietary Lightweight Spokes and Brass Nipples:\u003c\/strong\u003e Precision lacing for optimal stiffness, durability, and power transfer.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e28-Spoke Option Available:\u003c\/strong\u003e Riders between 220 and 280 pounds can opt for a heavier-duty 28-spoke build for added strength and reliability.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax Rider Weight - 280 lbs:\u003c\/strong\u003e Custom options are available for heavier riders - simply contact us for details.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand Built in Denver, Colorado:\u003c\/strong\u003e Every wheelset is individually assembled and trued by skilled builders for a level of craftsmanship that factory wheels can't match.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eHub Options \u0026amp; Which to Choose\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eROL CLD Hub:\u003c\/strong\u003e ROL's own centerlock disc hub - a high-performance, reliable hub built specifically to complement the GP45 Carbon.

Tubeless compatibility, broad tire clearance, and a rim profile engineered to reduce turbulence mean you're always set up for the best possible ride, no matter the conditions.

For road-focused riding, 32C-40C tires are a sweet spot. For gravel racing or bikepacking, 40C-50C tires will take full advantage of the wide rim profile and tubeless compatibility. The wide bead seat also optimizes tire shape for better aero performance and rider comfort compared to narrower rims.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre these wheels tubeless compatible?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eYes - the GP45 Carbon features a semi-hooked tubeless-ready bead, making it fully compatible with tubeless tires and sealant setups.
