Ellsworth Evolve SST.2 SRAM X.9 Complete Bike: The all new 100mm travel Evolve sst.2 with ICT Technology is dialed in to maintain the legendary efficiency, handling and ride of a nimble full suspension cross country bike while harnessing the rolling efficiency and feel of the 29" wheel. The new Evolve hammers up and down hills with geometry characteristics and suspension functions designed from the ground up to optimize the fast rolling, higher stability of the larger wheel, eliminating the ill handling commonly associated with the 29" wheel bikes. The NEW super formed pivot integrated seat tube is lighter and stronger while the NEW semi-integrated tapered head tube is stiffer and more responsive. The wheels afford you the surefootedness of an XC Trail bike that will feel like an old friend and soak up mistakes at the start and finish of any ride. Fast and agile, aggressive and plush - destroy your inhibitions with the Evolve.
