If you’ve followed the news over the past few weeks one thing is clear: Plus-bikes are the new trend! But many bikers are still sceptical about the new wheel size. Rotwild presents a model which can do both: 27.5″ and 27.5+. The new R.X1 FS leaves the decision up to the consumer. Alongside the wheel size the bike can be adapted to the rider’s needs in other ways, find out how here.

But with it’s hydroformed tubes the new Rotwild R.X1 FS isn’t just a real looker, it is also chock full of interesting and exciting technical details. For the first time in their company history Rotwild offer a bike that allows the rider to choose between 27.5″ and 27.5+ wheels.

Compatibility and multifunctionality

Rotwild achieves this variability by using the Multiple Dropout Inlay-system (MDI III), which allows the chainstay length to be varied between 422.5 and 435 mm. The shorter setting is aimed at trail riders seeking agile and playful handling whilst the longer setting offers greater traction and stability. The head tube angle can also be varied by 1.5° using adjustable headset cups.

Technical highlights of the bike

Along with the variable chainstays the new Rotwild R.X1 FS also features additional interesting technical features. These include completely integrated cables, the supplied Anti Chain-Suck-Ring, which fits to the ISCG-mount or the double row bearings at the Horst link which should increase rigidity of the Boost rear end.
