eMTB full carbon frame with optimal weight to stiffness ratio. Brose Drive S-Mag, 140mm DT Swiss chassis for lots of offroad fun.
The R.C750 is consistently well thought-out for Cross Mountain: from the full carbon construction of the frame, which stands out thanks to its high level of stability and stiffness and thereby precise riding behaviour, to the 750 Wh removable integrated power unit, which combined with the powerful Brose Drive S-Mag motor provides enormous range and power delivery.
The R.C750 Cross Mountain concentrates on the essentials: fun and lots of action. Our engineers paid particular attention to the chassis, the DT Swiss suspension element provides over 140 mm of travel, perfect for rugged terrain, roots and stones, or for easily jumping over one or the other. With its balanced all in one geometry, it feels just as at home with touring as it does on a quick circuit after work or on a challenging trail in the mountains.
The suspension fork is based on a combination of steel springs and a high performance air system for a sensitive and flexible early suspension, comfortable resistance in mid range and in end progression. The large negative air chamber of the damper also provides very sensitive responsiveness at the same time as having a linear characteristic curve. We have designed the rear triangle to be as small as possible with 460mm travel in order to further support traction and cornering. This allows the 29 wheels to develop their full potential and underscores the character of the ingenious all-rounder that is the R.C750.
