How knackered actually are they? You’d be surprised what’s fixable on a set of rebas as long as the stanchions aren’t buggered and there isn’t slop in the bushings.
They’re losing air but main problem is with only 60psi in them they feel stiff as hell. You can push down on them really hard and it takes a lot to get them to move. But despite the very stiff initial movement, they still bottom out very easily on any bigger hits!
I can’t remember the technical details that the Local Bike Technician told me but he said he’ll never be able to get them to 100% again, maybe 60-80% of what they were when new. He said it will be £80+ and chances are the forks might be back in the same situation again 3-6 months later. Finally he recommended those aforementioned forks to me.
Otherwise that’s a big step down – you’ll do much better with a decent set of second hand ones.
That’s what I’ve been thinking. Saw a Rockshox Recon Solo Air 120mm on Ebay, hardly been used, £150-£200. Something like this looks like it might be a better option.
