is this somehow normal ?
pretty new shock on a trancex - about 10-20hr riding on it
works very well, nice & smooth throughout but when you 1st get on and weight the suspension there's a different slightly hissy, almost gritty noise right at the top of the stroke
(never hear it once I'm on there as it's well within the sag of the shock - I guess happens very briefly on landing my MASSIVE jumps maybe but drowned out by cheers at those points)
Shock's never been apart but I did depressurise it once, FWIW
Any thoughts, pleasey thanky ?
Could well be cavitation, ring Mojo.
Cheers, yes sounds like I'd imagine cavitation to sound but in my mind that'd only happen at fast speeds and I can reproduce it at any speed, even really slow
Am I just misunderstanding cavitation ?
any speed
That happened to my RP23 on my last bike. Sent it back to Mojo and they serviced it and put new seals in (despite me telling them that I had already done that myself). Came back with the same problem. Sent it back to Mojo again and this time they fixed it properly and the grinding/rough noise in the first part of travel was caused by a failed component inside. The shock then worked ok but the RP23 isn't that great anyway particularly in the mid stroke as it blows through it's travel too quickly.
Decided to cut losses and get TF to PUSH it. Came back a totally different shock, felt amazing particularly through fast corners and never heard a peep from it again. Just sent new RP23 on new bike for the same PUSH tune from TF, yes it's a lot of dosh but to have a totally reliable shock that feels like a shock of that price should is priceless.
Don't let Mojo fob you off with just a service, it will need new parts inside.
oh, just found this again - had given it up
thanks for the info
