rockshock u turn forks, if you use them wound down, knock.
clunk clunk they go.
its not a fault, and not a problem, its play in the U turn assembly, but if your going to go with rockshox go with some that are fixed at 120, or Maxium 120.
dont bother with 150s and just think “oh i’ll just run them wound down”
itl drive you nuts.
you COULD get some fixed travel ones, and a travel reducer kit, which would give you the benefit of stiffness from a 150, but with less travel. (and you can always swap out the travel reduction for a longer setup if you ever change your frame)
