XC Bikes: Built for Speed

Cross country bikes prioritise low weight and pedalling efficiency above all else. Every gram is scrutinised, and suspension is tuned for speed rather than plush comfort. The result is a bike that flies uphill and rewards fitness.

XC bike features:

  • 80-100mm suspension travel
  • Lightweight carbon or aluminium frames
  • Steep head angles (68-70??)
  • Often under 10kg total weight
  • Efficient, firm suspension
  • 29er wheels standard

XC Racing vs XC Marathon

XC bikes serve two racing disciplines: short-track Olympic-style XC and longer marathon events. Olympic XC bikes are the lightest and most race-focused, while marathon bikes add a touch more comfort and control for multi-hour efforts.

Why Buy Used?

High-end XC bikes represent serious investments in carbon and weight savings. The used market offers race-proven machines at accessible prices, often with carefully maintained suspension and components.
