The sport of mountain biking originated in the 1970?s. Today, off road biking is not only very popular it is getting highly specialized as well. As more and more riders are looking for greater challenges, it is only expected for downhill or DH biking to evolve. DH bikes have unique features that meet the requirements of the sports. Find out what specs does mountain bike types ? downhill bikes have in this short article.
If you place a DH MTB alongside an XC bicycle, you will notice right away that one has a very robust construction. Downhill biking places such high stress on the bicycle frame that bikes of lesser build would not last very long. Modern XC designs typically weigh from 11 to 15 kilos while it is hard to outfit a true blue DH rig that weighs near 18 kilos.
The sport of DH racing is clearly more dangerous than other MTB rides. Most DH riders wear more protection. They use full face helmets and body armor. DH rides occur on steep slopes. These are the same slopes that are used for skiing in the winter. Most speed records from MTB races are usually from DH races.
Loyalists of cross country MTBs counter that downhill tracks are a natural part of cross country trails. It should be noted that DH bikes are designed to match the rigors of the sport. Aside from robust construction, some cross country MTB features are minimized in DH rigs. For example, there is only one chain ring in a DH bike. There is a heavy guard called a bashring that protects the chain and chain ring from damage when it strikes rocks and boulders present in a DH course. A DH bike would make a very poor XC bike because of weight and design differences.
The suspension system of the bicycle is often deeper than that of XC rigs. Travel is often eight inches or more in order to accommodate very hard landings and to get the most traction. A standard feature of most DH rigs is the dual crown fork that makes possible very long travel for the front suspension.
The sport of cross country riding is an endurance sport while DH biking emphasizes upper body strength. Technical finesse is required because that is the nature of a DH trail. Off road biking when taken to the extreme is downhill biking.
A DH MTB is a specialized off-road bicycle setup. The design sacrifices weight but makes up for robustness and speed. Because of the trade-offs built into the design of DH MTBs, it would perform poorly as a general purpose XC MTB. But when you do extreme things with mountain bike types ? downhill bikes, it would perform admirably.
