Braking Technology

The inclusion of disc brakes is a standard feature of tout terrain bikes. This is because of the established benefits that this braking technique implicated on the bike in recent years. Like any technology, of course, also disc brakes involve disadvantages, which are however negligible in terms of safety benefits.

Advantages

  • Brake effort : disc brakes have a much higher brake power than rim brakes.
  • Braking in the wet : the braking performance of a disc brake in the wet or snow is falling at a much less strong than of a rim brake. These rapidly decreasing braking performance of the last-mentioned technique significantly increases the risk of accidents.
  • Rims will fail after a certain mileages if used with rim brakes. If the rim is worn out due to many kilometeres you will see wear on the rim flange. A rim brake needs consistant monitoring as a failing rim might result in severe accidents. 
  • Structural parts are not used as a braking body: the disc is an independent component of the wheel bearing. Rim brakes use a load-bearing component (rim) and brake body. Thus, wheels break under severe wear because the edges are worn and therefore it can lead to serious falls. But also to repair defects are very complex, since the entire rim to be replaced. This can lead to major problems on longer trips.
  • On longer descents a rim of a rim brake bike can become very hot which might result in a flat tire.
  • A defective front wheel does not result in a defective brake system.

Disadvantages

  • Disc brakes might cause some noise under certain conditions, mainly in we weather. The use of larger discs, ie. 200mm an bigger, can result in some nice. However, the will not affect rolling resistance.
  • Noise however can also be experienced with rim brakes under wet condition or if not maintained properly.
  • Discs can bend and need to replaced. Compared to rim brakes however, the defect of the wheel does NOT result in the defect of the brake system.
