I’ve got a set of Rockshox Revelation U-Turn Air forks.
The travel adjuster was stuck solid.
Dropped the +/- air out of them.
Removed the top adjuster cap, one of the ballbearing had slipped off the spring.
The ballbearings seem a bit rusty.
Cleaned them up, the best i could.
Is it worth packing grease in there….?
Also what size are the bearings..?

Yep, grease ’em up.
They need cleaning out once a year or so
You need at least 3 bearings on springs under the cap so it will turn smoothly

Size? Take on into your LBS and say ‘Can I have some this size please!” 🙂

When were the forks last serviced properly though…? Sounds like they might need doing! 🙂
