If I read your part number right, you need the 140mm 26″ shaft – I think they’ve only recently started doing them I think – there’s a new 140mm Pike dirt jump fork right? – but if you can find a 150mm 26″ shaft, you simply need to remove 10mm from the bottom, I think the thread is long enough that it doesn’t need to be tapped, so it’s just a question of shortening and installing. I’m guessing it’s for a 650b?
I went through the same thing looking for a 140mm 26″ shaft and eventually ended up doing that because at the time, they simply didn’t exist in the real world.
Have you been in touch with LoCo?
