I have an old set (pre bulge) of 29er Reba’s that have push damping which I like

I have a new set of 15mm 29er Rebas which don’t have PUSH and which I want to get Pushed

Can I get the PUSH system from the old forks into the new ones?

also is a TF Tuned job or can someone like Loco or Rebound do it?

If the travel is the same on both forks should be doable, can certainly have a look and adjust as necessary or you could add later model damping whihc is a s good or better than the push stuff and can be tuned too. 😉

Probably, assuming the dampers are the same length

Its a pretty simple job to be honest.

The damper is a self contained unit. Just undo the bolt on the right leg and there it is.

You might as well change the damping oil while you are at it

EDIT or have Loco do it for you!

The 15mm forks look fairly new, how do I tell if it is one of the newer tuneable ones?
