Fork set up – Rev U-Turn’s

Ok i have the correct amount of sag in my forks when sat on the bike stationary (25%) but under braking and on botched landings they dive more than i would like (i am a heavy rider). Am i ok to increase the pressures which i assume will lessen the sag and if so should i top up the – or the + chamber first (sorry i can never remember)

Cheers

25% sag is a starting point, its not the ‘correct’ amount of sag. Fork setup is a trial and error process until they are right for you and your riding; adjust pressure in +/- by 5 psi, go out riding, adjust accordingly, go out riding, adjust accordingly…until ‘right’. 🙂

Not heard that either chamber should be adjusted first.

Compression damping can help reduce brake dive but will typically reduce small bump sensitivity

Empty -ve
adjust +ve
adjust -ve

I run Pikes rather than Revs but I think setup is the same.

Firstly IMHO I reckon that 25% sag is too much – I run around 20%. The positive top chamber sets the preload or sag, and the bottom negative chamber determines how much “help” is given to initiate the fork travel. The more pressure in this chamber, the faster the initial movement.

Therefore suggest you try enough positive (top chamber) pressure for 20% sag, then set the negative pressure at 5 PSI less than that and take it from there. I weigh 82 kilos all up with pack and run 125/125

Can you not run a little motion control? firm them up a bit?

doesn’t that just slow the compression and return down or am i thinking of something else ?

Motion control is RS’ take on compression damping. Rebounding damping is on the bottom of the right leg. Slowing the compression down a bit is what you want isn’t it, if you’re going through the travel too quickly? On mine it’s a little lever on the top of the right leg, set anywhere between fully on (more or less locked out) to fully off, (completely active fork) adjust as necessary without affect spring rate. (amount of sag).

Agree you can use some compression damping (wasn’t sure if the Rev’s had it), but its worth trying less air in the negative chamber first as this will lessen the tendency of the fork to blow through the first part of the travel as it hits.

Yep absolutely. It’s all about playing with the settings to get it doing what you want

Ok cheers guys. I’ll have a fettle and see where that gets me 😀

bigsi, mail me please.

Clubber is right with the order, but if you’re heavier than average try 10pis LESS in the -ve chamber, maybe 15.
It changes the feel of the fork quite markedly – nProps them up nicely
