I have a Mattock Expert, almost the same they both have the similar features but Expert is open bath rather than a cartridge. I absolutely love the fork think its fantastic especially the damper, its miles better than the Rockshox Motion Control RCT3 damper on my SID and Revelation.
The air spring is relatively linear so you get good small bump compliance but the well controlled damping gives you support in the mid stroke and HBO allows you to tune how you want the end stroke to feel to prevent any harsh bottom outs. Since getting the fork I find I can ride rough sections with more composure and speed, specially repeated large hits; the forks seems to recover quickly ready for the next hit without bucking me about or packing down. Off camber rooty sections are easier too as the fork is more supple and front end feels like it has more grip.
Setting up the fork took less time than RS Moco forks, even though there are more knobs to turn. Because the TPC damper is far more intelligent compared to RS Moco it already puts the damping parameters inside the roughly the correct operating window so you only need 5 clicks of rebound adjust to find your sweet spot, rather than RS’s 16 clicks of adjustment. This meant bracketing tool a lot less time and I felt I had all the adjustment I needed from too much to too little.
I’m not trying to bash RS by repeatedly saying the TPC damper is better than the old Moco. All my previous forks have been RS Moco damped forks so its the only thing I can compare it to.
