Frame: WLS series frames get all the features we can muster to make the double butted aluminium chassis even lighter, stiffer and more efficient. The 6061 aluminium tubes feature complex mechanical forming, while the bottom bracket uses the PressFit standard and there's a tapered head tube, too. We also incorporated the IS brake mount into the 3D forged dropouts, while internally routed cables give an exceptionally neat appearance and ensure long-lasting clean gear shifts. The 27.2mm seatpost contributes to greatly enhanced rider comfort and our Agile Ride Geometry with a shorter, lowered top tube makes the SL a balanced and agile companion for female riders out on the trail.
Agile Ride Geometry
We ran innumerable tests to develop the Agile Ride Geometry in our series of big wheel bikes. We also added the 27.5in wheel size to the very well received portfolio. Three important details lead to the very agile character. Increased fork offsets let us achieve the same trail as our 26in bikes without having to steepen the head angle, thus maintaining generous toe clearance to the front wheel. Secondly we shortened the chain stays without compromising the seat angle. We invented a patented construction to mount the front derailleur to give us more tyre clearance while keeping a conventional seat angle, leading to a perfect riding position for every rider size. Last but not least we kept the BB height the same as on our 26in bikes. These measures lead to a natural riding position. Every mountain biker will feel immediately at home on a CUBE 29er or 27.5.
