JANTA NEWMEN ADVANCED SL X.R.25 28H 29inch Like all Newmen carbon rims, the Advanced SL XR25 impresses with first-class mechanical properties and very low weight and is the ideal basis for a light Gravel wheelset. Due to the hookless construction, it is predestined 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 to increase the service life, the spoke holes were drilled in a special process without damaging the structure of the carbon fibers. The inner width, which is generous for Gravel 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: intended use : Gravel, Cyclocross, Cross Country Material: UD carbon Rim Type: Clincher (clincher and folding) Brake type: only for disc brake ETRTO: 622x25 EARTH: 600mm Inner width: 25 mm Outer width: n/a Rim height: kA Offset: no Number of holes: 28 holes tubeless capable: yes ASTM classification: n/a recommended tire width: 35-61 mm maximum tire pressure: 2.2 bar (61 mm) - 3.5 bar (35 mm) 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 glossy black decals Weight according to the manufacturer: 310g
