I LOVE my Manitou Revox!
It’s on my 222 and it works flawlessly. I really like the Manitou SPV system. It allows you to get the basic tune custom to your needs. The more air you put in, the more propedal you have (and consequently less small bump sensitivity). You can then adjust the bottom-out resistance to make a very progressive shock. If you just want that, buy a swinger 4-way, but if you splash out on the 6-way, you can fine-tune the compression stroke (both high and low adjusters!)
You don’t get that sort of stuff on Fox bar the higher end DHX stuff!
Oh and Manitou Swingers have a fair bit of scope for modifications. A classic one is to gut it and put the shim stack from a Manitou Metel in to create a more supple shock with better small-bump responsiveness. However a far easier mod is to replace the main O-ring seal in the body with a softer one. Its stock at about 100 Durometers, but if you replace it with a 70a ring instead you get far less stiction.
Oh, and you can home service manitou shocks
IN YOUR FACE FOX WITH YOUR SILLY FIXATION WITH (near) POINTLESS NITROGEN CHARGING!!!! 8)
As for Rockshox, Peaty’s been running a Vivid Air, as has his team mate Greg Minnar, so they can’t be that bad!
EDIT:
Mildred, that’s just oil moving through the damping system. Nothing to worry about, Manitou Swingers tend to make the same kind of noise if you push them deep into their travel.
