Powerful technology for efficient training

The low-maintenance Kevlar V-belt drive with magnetic resistance system ensures a quiet, smooth ride. The 24 resistance levels enable precise training control - from moderate endurance rides to powerful intervals. The integrated quick-stop function increases safety during intensive sessions.

Ergonomics & comfort without compromise

The stable V-frame construction contributes to high stability. The saddle and handlebars can be adjusted horizontally and vertically four times to achieve an optimum sitting and grip position. The Studio Curved handlebars offers natural, ergonomic hand positions for long training sessions.

The combination pedals (SPD click system + cups) allow flexible training with clipless shoes or sneakers. Comfort saddle, stretch pads, integrated bottle holder and practical media storage round off the package.
