Pure speed efficiency, it’s a cheat code for off-road racing, with Ethos SL rims, DT180 hubs and Berd Spokes.\u003c\/p\u003e\n\u003cp\u003eUltralight. Uncompromised. Unmatched.\u003c\/p\u003e\n\u003cp\u003e993g is ridiculously light, but lightweight alone wasn’t enough. The SL180 is a purpose-built ultralight race wheel designed to exploit every meaningful gram. With a 30mm internal width and a full 28 spoke count front and rear, it avoids the concessions other ultralight race wheels make. Every detail serves speed. Revised carbon layups utilize T800 and T1000 layers to trim weight,\u0026amp;nbsp;and the rim profile is engineered specifically for the industry-leading hubs and spokes it's built with. The result is the world's lightest 30mm internal-width production XC wheelset.\u003c\/p\u003e\n\u003cp\u003e28 SPOKES: Going light doesn’t mean recklessly cutting weight.

They feature 30mm internal front and rear widths, and a 20.5mm depth, delivering optimal torsional stiffness and power transfer for a race-day wheelset with an ultralight layup. Available only in 29” with a full 28-hole spoke count.\u003c\/p\u003e\n\u003cp\u003eDT Swiss 180 Hubs\u003c\/p\u003e\n\u003cp\u003eExceptionally light and reliable at just 283g for a set, and engineered in Switzerland, these hubs feature ceramic bearings and a 36 or 54-tooth ratchet system\u0026amp;nbsp; for reliable engagement and efficient power transfer. Designed for ultralight performance with a proven track record of reliability, DT180 hubs are the perfect match for the sub-1000g Ethos SL180 wheelset.\u003c\/p\u003e\n\u003cp\u003eBerd Polylight Spokes\u003c\/p\u003e\n\u003cp\u003eMade from Dyneema®, Berd spokes offer an industry-leading strength-to-weight ratio—up to 12 times stronger than steel by weight—while weighing less than half of traditional steel spokes. Their fiber construction naturally absorbs high-frequency vibrations, reducing trail feedback and improving traction while delivering a smooth, controlled ride feel that remains efficient under pedalling forces.\u003c\/p\u003e\n\u003cp\u003eWarranty\u003c\/p\u003e\n\u003cp\u003eAll NOBL rims come with a lifetime warranty, call it ride insurance.

It tests to 105J impact strength, exceeding most SL competitors (typically 85–95J), achieved through an aggressively weight-optimized layup and ultra-thin sidewalls.\u003c\/p\u003e\n\u003cp\u003eCompared to the Ethos SL, the Ethos XC is a more durable platform for everyday riding. At 1175g, it’s an exceptionally light wheelset while delivering 21% greater impact resistance, increased torsional compliance, and a more robust sidewall layup.\u003c\/p\u003e\n\n\u003cp\u003eRim Specs\u003c\/p\u003e\n\u003cp\u003eWeight: 270g\u003c\/p\u003e\n\u003cp\u003eWheel Size: 29″\u003c\/p\u003e\n\u003cp\u003eInner Width: 30mm\u003c\/p\u003e\n\u003cp\u003eDepth: 20.5mm\u003c\/p\u003e\n\u003cp\u003eBead thickness: 2.9mm upper, 2.4mm lower\u003c\/p\u003e\n\u003cp\u003eHole Count: 28h\u003c\/p\u003e\n\u003cp\u003eMax PSI: 40\u003c\/p\u003e\n\u003cp\u003eERD: 595mm (Front and Rear)\u003c\/p\u003e\n\u003cp\u003eWheelset Specs\u003c\/p\u003e\n\u003cp\u003erims: Ethos SL 270g (28h, 29”)\u003c\/p\u003e\n\u003cp\u003ehubs: DT Swiss 180 with ceramic bearings\u003c\/p\u003e\n\u003cp\u003ehub spacing: Boost\u003c\/p\u003e\n\u003cp\u003ebrake type: Centerlock\u003c\/p\u003e\n\u003cp\u003efreehubs: XD, MS, \u0026amp; HG\u003c\/p\u003e\n\u003cp\u003espokes: Berd Polylight Dyneema\u003c\/p\u003e\n\u003cp\u003enipples: Sapim Alloy Black (Polyax DS Securelock)\u003c\/p\u003e\n\u003cp\u003edecals: White, Chrome Silver, Chrome Gold, \u0026amp; Black\u003c\/p\u003e\n\u003cp\u003eValves: NOBL Tubeless Valves\u0026amp;nbsp;(Upgrades to Peaty’s Valves available)\u003c\/p\u003e\n\u003c\/div\u003e","brand":"NOBL","offers":[{"title":"Default Title","offer_id":42130697420855,"sku":null,"price":1087.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/2046\/files\/ethos-sl180-square-white-1536x1536.jpg?v=1772645469","url":"https:\/\/www.probikesupply.com\/products\/nobl-ethos-sl-dt180-29-boost-centerlock-wheels","provider":"Pro Bike Supply","version":"1.0","type":"link"}
