A wee bit of info that might help someone else with the same issue. I recently bought a 13 pikes peak and had great difficulty getting the front to sag properly. I'm only 70kg so thought i night need new springs. After a few brief chats with suspension shops, it appears that no one has needed this so far. Keen to investigate, and handy with the tools, I bought a fork cap tool and a workshop manual and set about the passive (right)leg. My theory was that I'd get a shop with a spring dyno to get the current rate and then find an alternative lighter one. Fortunately I never needed to go this far. As I wound back the cap there was a lot of air release, far more than I've ever had on any fork before. I put it back together and hey presto 10mm more sag and no more topping out. Took 1 hour and a £30 tool. Update. I opened the active side last night also, and although I heard no whoosh of air, I got another 15mm of sag!! Now around 50mm. Rides far better now
