When Dirt magazine was looking for the ultimate hardtail to compete in one of the world’s most gruelling mountain bike races, the Alpe Duez Mega Avalanche, they chose the Alpine.
The Alpine also served its apprenticeship by being thrash tested throughout the 07 season by the www.trailAddiction.com guides out in Les Arcs and the surrounding Alpine areas.
trailAddiction also completed the “Everest in a Day” challenge (9300 vertical metres of descending in one day without riding the same trail twice) for What Mountain Bike magazine on their prototype Alpine frames.
So after what is probably the most gruelling and comprehensive R&D/product testing ever undertaken for a hardtail frame, the Alpine is now available as a dialled bikes production frame.
Designed around a 130-160mm travel fork (though you can use just about any single crown fork on this frame), the Alpine is constructed of Reynolds 853 (top and down tubes), Reynolds 520 (seat tube) and 4130 cro-moly (everything else). Head angle is relatively slack for stability when tackling technical terrain or descents. But seat angle is relatively steep to help keep the front end down when climbing.
