Anyone done it? Big improvement? What's it all about?

mine is done old one i found if set up to be correct sag/use the travel it bobbed too much and if set up to not bob it was too harsh

now it hardly moves when climbing but still feels supple and uses all the travel when needed

Is it done specifically for rider weight?

yeah it was in weight bands iirc

Had a quick go on my friend's pushed rp23 last weekend and was very impressed.

Getting my Float R pushed when serviced this week as a result.

I'm guessing you keep the Propedal on a Pushed RP23?

Reading the info on www I don't think you do. Seems to imply PP comes off.

mine still has the propedal lever but i just leave it off all the time and its great up and down

Excellent. May try and send it off next week.
