Intermediate-modulus fibre for toughness and impact resistance, high-modulus fibre where stiffness and low weight matter most. Hookless tubeless ready. Boost thru-axle standard. No system weight limit. Race-grade spec at a price that makes carbon accessible to riders who ride hard and spend carefully. That is the Concept Speed calculation.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eYou already know what heavy stock wheels feel like on a climb. That dull, dragging resistance when you stand on the pedals and the bike just... lags. These wheels fix that. Rotational weight is the weight that fights you the hardest, and at 720g front and 830g rear, there is very little of it here. First climb out of the saddle, you feel it. The bike snaps forward. It responds to you.\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe hookless carbon rim runs tubeless only, which means lower pressures, more traction, and a tyre that moulds to the trail instead of bouncing off it. The 30mm internal width gives your tyre the support it needs to corner properly at those pressures. Maximum 3 bar (44 psi), recommended 2.3 to 2.6-inch tyre. Everything works together because it was thought through together.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe Concept Speed 6-bolt disc hub runs on TPI sealed cartridge bearings and a 36-tooth ratchet ring with 10-degree engagement. 36 teeth, 36 engagement points.

Hookless tubeless lets you run lower without the pinch flat risk of a hooked rim with an inner tube. The trail feels different, roots that used to bounce you now compress under the tyre. Loose corners that used to push the front wheel now grip. You carry more speed through technical sections not because you got faster, but because the wheel is working with the trail instead of against it. The 30mm internal width is what makes this possible at the tyre widths XC racers actually use.\u003c\/span\u003e\u003c\/p\u003e\n\u003col start=\"3\"\u003e\n\u003cli\u003e\u003cstrong\u003eBoost axles and sealed bearings keep the wheel tracking true under hard efforts\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003e\u003cspan\u003e15x110mm front, 12x148mm rear. Boost spacing exists because narrow axles flex under hard cornering and braking loads, and flex is speed you are not converting into forward motion.

Pair that with TPI sealed cartridge bearings, 6902x2 front, 15267x4 rear, and you have a hub platform that spins smoothly and stays precise from race day to training day and back. ERD is 592.5mm, maximum spoke tension 150 kgf, recommended 110 to 130 kgf.
