Stoll builds a record-breaking hardtail
A hardtail with a head angle of 68.8 degrees? A frame weight of around 780 grams? A frame price of 4000 francs? These attributes don't fit many mountain bike frames, but they do fit the brand new hardtail from the young bike manufacturer Stoll Bikes perfectly.
The company's prologue was the trail fully "T1" in summer 2016, and now the second product, the hardtail "R1", is rolling into the portfolio. The two bikes have a lot in common: the details of frame construction are defined in close cooperation with the customer, and the design of the carbon fibers is tailored to the weight and preferences of the customer. The frames are then produced by hand with the utmost care by carbon specialist "Bike Ahead".The chain and seat stays on the "R1" frame are particularly eye-catching, Thomas Stoll says: "Details such as the tapered chain stay and the pre-bending of the seat stay guarantee maximum traction on the rear wheel. The low center of gravity and flat steering angle help the R1 achieve maximum performance."According to Stoll, production of the hardtail will start at the beginning of October 2017. The record-breaking low frame weight of 780 grams refers to the pure carbon frame excluding aluminum parts such as the derailleur hanger (18.5g), the seat clamp (9.0g), the cable clamp (4.5g) or the rear axle (21.5g).
As Stoll manufactures customized frames, the weights of the frame also vary. A rider weighing up to 85 kilograms can ride the lightweight frame of 780 grams, while heavier riders have to reckon with around 100 grams more prepreg carbon between the head tube and the Boost dropout.
In close consultation with the customer, Stoll also offers complete bikes. Weights from 6.9 kilos are possible for the "R1", which relies on press-fit bottom brackets and single-chainring-only.
