Tom Ritchey is unique. Although president of his company and chief designer, he still manages to ride around 15,000km a year and put his riding knowledge into practice.40 years of innovation - Tom Ritchey was a central figure in the early days of mountain biking - setting the direction in component design and using new materials for all sectors of cycling.
The reputed durability of Ritchey products is due to stress testing exceeding the required standards several times over. The result - the best weight/strength ratio of components on the market. Ritchey steel frames, always personally welded and tuned by Tom during test rides, consulted with top racers and then manufactured to the highest quality, have become the stuff of legend.
