JANTA NEWMEN ADVANCED SL X.A 30 28H 29inch Like all Newmen carbon rims, the Advanced SL XA30 rim consists of high-end UD fibers and impresses with first-class mechanical properties and extremely low weight. It is the ideal basis for a light cross-country wheelset. The hookless construction predestines them for tubeless use. The significantly reinforced rim flange withstands possible punctures better and allows driving with little air pressure. In order to avoid weak points and increase the service life, the spoke holes were drilled using a special method. The inner width, which is very large for cross-country rims, also gives wide tires a reliable hold. The shape of the tire is rounder due to the flanks being placed slightly outwards, which means that a significantly better cornering grip and increased safety are achieved.Technical specifications: Area of intended use : cross country Materials: carbon Rim Type: Clincher (clincher and folding) Brake type: only for disc brake ETRTO: 584x30 EARTH: n/a Inner Width: 30mm Outer width: n/a Rim Height: 20mm Offset: no Number of holes: 28 holes tubeless capable: yes ASTM classification: n/a recommended tire width: 58-66 mm maximum tire pressure: 2.5 bar Maximum system weight: 130 kg (rider, bike, clothing and possibly luggage) maximum spoke tension: kA Features: - Valve hole bore: 6 mm (SV) Finish: UD matte Colour: black with white and silver-grey decals Weight according to the manufacturer: 320g
