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\u003eEthos Ti70 Hubs\u003c\/p\u003e\n\u003cp\u003eBuilt to match the performance of Ethos rims and the world’s lightest spokes. Developed by NOBL in collaboration with Berd and Erase Components, it pairs a lightweight titanium freehub with a fast-engaging 70-tooth star ratchet system for a crisp 5.14° engagement, ensuring precise power transfer on every pedal stroke. Berd’s proprietary Hook Flange design makes spoke installation secure and straightforward while optimizing strength at the interface and maintaining compatibility with Berd PolyLight X spokes. At just 331g for a centerlock hubset, the Ti70 is a lightweight, durable, and highly efficient hub that maximizes the performance of Ethos rims and Berd spokes, making it equally capable for XC racing and aggressive enduro riding.\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\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRim Specs\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWeight: 270g\u003c\/li\u003e\n\u003cli\u003eWheel Size: 29″\u003c\/li\u003e\n\u003cli\u003eInner Width: 30mm\u003c\/li\u003e\n\u003cli\u003eDepth: 20.5mm\u003c\/li\u003e\n\u003cli\u003eBead thickness: 2.9mm upper, 2.4mm lower\u003c\/li\u003e\n\u003cli\u003eHole Count: 28h\u003c\/li\u003e\n\u003cli\u003eMax PSI: 40\u003c\/li\u003e\n\u003cli\u003eERD: 595mm (Front and Rear)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWheelset Specs\u003c\/p\u003e\n\u003cdiv class=\"et_pb_module et_pb_text et_pb_text_12  et_pb_text_align_left et_pb_bg_layout_light\"\u003e\n\u003cdiv class=\"et_pb_text_inner\"\u003e\n\u003cul\u003e\n\u003cli\u003erims: Ethos SL 270g (28h, 29”)\u003c\/li\u003e\n\u003cli\u003ehubs: NOBL Ethos Ti70, Hook flange, Titanium Driver, 70T ratchet\u003c\/li\u003e\n\u003cli\u003ehub spacing: Boost \u003c\/li\u003e\n\u003cli\u003ebrake type: Centerlock or 6-Bolt\u003c\/li\u003e\n\u003cli\u003efreehubs: XD, MS, \u0026amp; HG\u003c\/li\u003e\n\u003cli\u003espokes: Berd PolyLight Dyneema\u003c\/li\u003e\n\u003cli\u003enipples: Sapim Alloy Black (Polyax DS Securelock)\u003c\/li\u003e\n\u003cli\u003edecals: White, Chrome Silver, Chrome Gold, \u0026amp; Black\u003c\/li\u003e\n\u003cli\u003eValves: \u003cspan style=\"font-size: 0.875rem;\"\u003eNOBL Tubeless Valves Stock\u003c\/span\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003e \u003c\/span\u003e\u003ci style=\"font-size: 0.875rem;\"\u003e(Upgrades to Peaty’s Valves available)\u003c\/i\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"NOBL","offers":[{"title":"Default Title","offer_id":42130698108983,"sku":null,"price":1087.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/2046\/files\/ethos-sl-square-white-1536x1536.jpg?v=1772804068","url":"https:\/\/www.probikesupply.com\/products\/nobl-ethos-sl-ti70-29-boost-centerlock-xc-front-rear-wheels","provider":"Pro Bike Supply","version":"1.0","type":"link"}
