R.G+ FS

Ultra 40

A downhill bike for everyone who likes to bike without shuttles and lifts. The R.G+ comes with 27.5" wheels and 200 mm chassis and a 500 Wh integrated power unit made from carbon with integrated shock absorber attachment on the drive. The 100% decoupled Brose drive system does not generate any additional resistance after cutting out and allows light pedalling. Individually adjustable levels of support as per your personal preferences - from very efficient to an extremely powerful mountain bike. The new XLS chassis is specially aligned to the FOX X2 Air shock absorber and the anti-squat is optimised to the higher chain hoist of an electric drive. The MSH I headset allows 3 adjustments to the steering tube angles so that the dynamic characteristics of the bike can be set according to individual requirements. The newly developed Multiple Dropout Inlay (MDI III) inserts allow the chain stay length to be changed so that adaptations specific to body size can be carried out and riding dynamics can be changed. The R.G+ also has integrated cable routing for the lowerable seat post and offers a tyre clearance up to 27.5 x 2.6.
