If I recall looking at one. The 2 way ratchet system is just different and not set up the same as hrx or hrr. Again look at a parts breakdown. It’s hard for me to explain typing it without pictures.
Put it this way. You won’t find a complaint about it online or anywhere having any drag whatsoever. I haven’t see a complain about it once. Would roll down a 1 degree slope. Not kidding. The trans doesn’t run through the height adjusters like older models because of new height adjuster which does both rear at same time
