Components

• Brakeset

  Regardless of the conditions you ride in (dry/wet/muddy), the hydraulic Tektro TKD88 disc brakes at the front and rear provide powerful and progressive braking. Oversized 180mm diameter discs provide even more power.
• Saddle

  Since your mountain bike rides will get longer and longer, it is important to have a suitable seat. Our teams have designed the exclusive Rockrider Ergofit Evo saddle. It fits all hip sizes and has a curved shape that is particularly good for sport trail rides. The 31.6 mm aluminium seat post ensures compatibility with most adjustable and suspended seat posts on the market.
