I have a set of Mattoc Comps 27.5 which have been well used for 4 months. Fitted to a Stereo 160, “puke green”. The comps are not anything new regarding damping as they are fitted with a Mars damper. Still nice though, very plush and sit up in their travel. They feel stiff enough for me and track well. I am going to upgrade to a set of experts or pros when more long term results come through. It’s not possible to install a expert/pro damper as the threads are different.
I’ve had them on natural trails, flat through steep, trail centres and dh tested on the Dunkeld classic dh.
I have a few niggles. Specific tools are required to service them, which aren’t cheap considering it’s 3 sockets. They are very easy to service once you have the tools.
Not much room between tyre and fork arch for a mudguard and it’s a pain to fit due to the reverse arch, can be done though.
Not much service info on Hayes group site for the comps, actually none, you’ll have to email Hotlines or Manitou for specific details. I eventually used a combination of the Mattoc guide and the Minute expert guide.
I would recommend a set of Mattocs, they function well, are easy to service and a bit different to the Pike invasion.
