Special Price CR4 DB Carbon

Limited for 50 sets.
Carbon spoke. 1080 grams. A special price wheel with same rim of 2025 CR5 DB at 21mm inner width but with a heavier hub. 

T1000
T1000 mixed rim with no compromise in strength.Tubeless, hooked and passes 100J impact test. The rim also can stand 140 PSI tyre pressure and 140KG spoke tension. Most rotational inertia is kept by reserving the rim weight, so flat road performance is not sacrificed.

Carbon Spoke
1.7 Grams with T1000 fiber and titanium metal part. Nearly 50% lighter and 25% stiffer than the best of steel spokes. Aero shape and individually repairable. Traditional mechanically connected carbon spoke type. More stable comparing with cemented carbon spokes that can work with steel spoke hubs.

Small Flange
Due to the excess stiffness of carbon spoke, we use small flange and less spoke for more comfort to balance. The flexibility reduces the power loss in viberation and thus improves the cruising performance also.

R280 Hub
A stable hub for carbon spoke, T head design so spoke is unlikely run out. Ratchet system and steel bearing inside.
