We made the switch to 165mm travel Rocky Mountain Slayers when it came time to hit the trails of Pemberton, a location known for its serious terrain. Just like on the cross-country day, we'd be earning our turns. The Slayer makes use of a relatively slack 66.5 degree head angle, great for charging the rock faces and steep chutes that made up the day's ride, but it could easily be a handful when the singletrack reversed direction. The technical climbing was made immensely easier though by flipping the fork's Dual Position Air (i>DPA/i>) lever atop the left fork leg, lowering the ride height by about 30mm to steepen the head angle by roughly a full degree. The DPA system, lifted from the Revelation fork lineup, works by transferring air between the positive and negative chambers. The system requires only a single added seal, basically eliminating the extra friction that is usually associated with air sprung travel adjusts.
