SSR - A new era in steel technology; the Reynolds 953 is age-hardenable, martinsitic stainless steel. This super metal has an amazing yield strength of 2000 Mpa, which means its twice as strong as titanium with a frame weight comparable to high-end aluminum. Oh yeah, and it wont corrode. Rider-specific tubing and geometry combined with exquisite welds make this steel frame stiff enough for the sprinter, light enough for the climber, and strong enough to last a lifetime. IF recycles all post production waste for even less environmental impact. Not only will the SSR last a lifetime, but is good for the environment in more ways than one.
