The new Graff Route wheels are designed for Gravel use. The aerodynamic profile of the new HM700 carbon fiber rim combines excellent speed and handling performance on both gravel and paved routes. The rim designed with a 36 mm profile and a 24mm hookless internal channel offers greater impact resistance, more stability when driving downhill thanks to the use of lower tire pressure recommended for gravel use. The recommended tires are those with the TLR system with a section starting from 35mm, with an inflation pressure not exceeding 4.5 bar (or as recommended by the tire manufacturer). The wheels lacing pattern with straight-pull 24-spokes front and rear make the wheel light and improve the distribution of the loads generated during pedaling. The X Graff hubs produced by Miche are CNC machined in Ergal 7075 HT, mounted on high smoothness bearings with simplified hub movement registration, even when the wheel is mounted, for fine adjustment through a special ring nut.Specifications:- Material: Carbon- Size: 28´´- Braking System: Disc center lock- Hubs Material: AL 7075 T6- Bearings: Miche sealed ball bearings- Compatibility: Shimano- O.L.D.: 100 - 142- Front Axle: 12- Rear Axle: 12- Rims: UD carbon fiber - Hookless HS- Rims Profile Height: F 36 - R 36- Spokes: Stainless steel black, flat, straight pull, double butted- Nipples: AL 7075 T6 / Black- Rim Dimension: 622-24C- Rim Inner Width: 24- Tire Type: Tubeless- Tire Dimensions: 35 mm÷50 mm- Spokes Assembly Pattern: 24 - 24/cross- ASTM Classification: 2- Max Weight: 108 kg (Bike+User)- Weight: 1.565 kg
