This 700c carbon tubeless rim pairs a 50mm V-profile with a 30mm outer width to improve tyre shape, grip, and high-speed stability while offering four verified weight tiers to match your build priorities.\u003c\/p\u003e\n\u003ch2\u003e700c Carbon Tubeless Rim — Designed for road and gravel builds\u003c\/h2\u003e\n\u003cp\u003eThe rim is tubeless-ready with a hookless-compatible bead seat and supports tyre sizes from 25c to 32c, making it suitable for race packs, fast training wheels, and mixed-surface rides where puncture resilience and lower pressures matter. Internal widths of 24mm or 25mm (specified at order) help the tyre assume a fuller profile that enhances cornering contact and reduces rolling resistance compared with narrower rims.\u003c\/p\u003e\n\u003cp\u003eComfort and confidence improve through tubeless compatibility: running lower pressures within the specified 100–125 psi range increases compliance on rough tarmac and gravel edges while the 30mm external width maintains lateral stability in corners and high-speed sections.\u003c\/p\u003e\n\u003ch3\u003eWhy it fits your
