Nitron makes 2 variations of the HPA depending on application: the HP1 and the HP2. One is the remote knob with the hand dial, which (again depending on application, R1 vs R2, and customer spec) may or may not be clamped onto the shock reservoir, but which is always attached by a hose to the preload adjustment collar. The other is the one you received—the adjuster is on the collar itself.After spending a few too many days held captive in Cincinatti by the USPS the R1 made it to me today. assuming this is NOT the usual remote HPA correct?

If not, how is this adjusted? Just with a nut driver? The OEM knob does not fit on there right?
I though the non-HPA used the traditional locking collars.
Nitron has typically spec’ed the R9Ts with the remote preload adjuster; they spec’ed yours with the attached version. Whether this is by design (new information, trying to achieve compatibility with bikes that do/don’t have the charcoal canister) or by error (on part of Nitron when building or your distributor when ordering) is anyone’s guess. They all work the same, however, so provided you’re comfortable turning a hex socket you’ll be fine.
