If you saw our Suspension Trends post, you already know that 20mm Boost is a thing. One of the most recent additions to the list of Boosted forks with 20mm axles is the new RST Revel V2, but there was a lot more in the RST booth than just new standards.
One of the biggest changes to the fork is obviously the 20mm Boost axle, but there is also an optional 15mm Boost axle that will allow you to run current Boost wheels with a 15mm hub. That seems to be the biggest reason for 20mm Boost – by moving the rotor spacing outwards, 20mm Boost now matches 15mm Boost which will allow you some flexibility in your wheel and axle choice if the fork allows for it.
The Rebel V2 is still an inverted design, but now it features mud guards to protect the lower stanchions. Available in 27.5+ or 29″ versions, the forks will be available in 80, 100, or 130mm travel for the 29er, or 100, 130, 140, and 150mm travel options for the 27.5+. There’s also three different versions with the Air TRL (Remote lockout), Air, and Air without Lock out.
With the recent push towards 29″ wheels for DH bikes, brands like RST are racing to get new version of their forks on the market that will accommodate the big wheels.The Killah 29 is RST’s dual crown DH fork with 38mm stanchions and a magnesium 20mm Boost lower. Available in 200mm travel only, the fork has a claimed weight of 3kg, and includes hydraulic compression and rebound adjustments.
Along those same lines, the RST Stitch 29 is a long travel single crown option for big wheels. Using the same 38mm stanchions, this fork has magnesium lowers that will accept 20mm Boost or 15mm Boost axles to run both hubsets. Offered in Air or Coil versions, both have rebound and compression adjustments and come in 160mm, 170mm, and 180mm travel. Weights are claimed to be 2.08kg or 2.37kg for air or coil.
The Coil version of the Stitch is new for RST in general, and it will also be available in 26 and 27.5″ versions. However, the smaller wheels also get smaller 36mm stanchions.
