Recently rebuilt my mates 140mm Travel Air U-turn 20mm axled Revelation 409’s for him as they had been leaking oil from the U turn adjuster (as is par I understand, certainly most Air U-Turn rockshox I’ve seen on the trails have been leaking!). Anyway, he’s ridden them once since I rebuilt them, was round his house today having a look at the bike, and funnily enough they’re leaking oil again!
Now, I used new o-rings and the lot when I rebuilt the forks, I’ve no real experience of the air U-turn system though really, but have serviced a fair number of the fixed travel dual air revelations/rebas/pikes in the past though successfully. So what’s the issue? How can I fix it?
Also, there seems to be a very annoying couple of mm of play in the forks (up and down) which results in a really rather annoying top out “clunk” when the forks extend fully. I’ve not come across this at all on any of the fixed travel dual air rockshox I’ve ridden. Is this normal? How is it fixed?
Cheers in advance for any info/feedback
