Ritchey Ascent Adventure Frameset

Details
The new Ascent is more adaptable than ever. The frame is tig-welded with heat-treated, triple-butted Ritchey Logic steel tubing that features rack and fender mounts and a third bottle mount under the downtube, while a new Ritchey steel fork offers up multi-purpose, rack, fender and dynamo light mounts. Other notable features of the new Ritchey Ascent include post-mount brake compatibility, 148mm spacing and an external seat collar. Throw a mountain bike bar on it and some 27.5" wheels for more trail-oriented adventures. Or ride it with drop bars and 29" wheels for some longer distance rough road riding. However you choose to roll, your riding possibilities are limitless atop the new Ritchey Ascent.
