My Monarch RT3 has been terrible, compress the shock till it gets to the point that it equalises the chambers and it has a big dive through the travel before becoming ultra hard to compress. i haven’t been able to resolve it in months, so…
Took it apart fully at the weekend and found loads of emulsified grease inside. Cleaned it out, rebuilt it with some Fox Float fluid and popped it back together. Its like a different shock now. took 5 minutes, god knows why i’d not done it before.
I’ve got a lovely pic of it below
