rendimiento Components
The Bass-X delivers premium components at a mid-range precio. The full 12K carbono horquilla takes the edge off rough roads and gives you sharp, confident steering — a big step up from alloy forks at this precio point. The sealed-bearing Mushroom buje conjunto de ruedas with Japanese bearings keeps everything rolling smoothly, and the 46t/17t gearing is perfectly tuned for flat urban riding. The flip flop buje gives you the freedom to switch between fixed gear and single speed by flipping the rear rueda — fixed for the full experience, single speed when you want to coast.
Full carbono horquilla
