Balfa 2Step 4X


The Balfa 2Step 4X shares its frameset with the 2004 2Step FR, but uses changed link plates. The plates reduce the bike’s travel from 5.3 to 4.3" (110 mm), slightly rake the head-angle out into 67 degrees and drop bottom bracket height to 13.5" (344 mm). It's built for 4X racing, slopestyle, jumping and general goofing around.

2Step is suspension design with temporary (moving with compression) pivot point. It is very similar to Maestro, or DW Link. Such design's advantages are good pedalling efficiency (little to none pedal bob) and close to none suspension feedback under braking (brake-jack).
