Raceface Turbine Z? R? on a Santa Cruz Tallboy. The lever has always had a bad action to it -- suprisingly hard to press compared to my other bikes' posts (fox, PNW). Additionally the dropper comes up a bit slowly and normally needs coaxed for the final 2-3cm.
A bike shop already replaced the cabling a few months ago. It seemed to help some, but soon fell back to its old ways. I don't know if the shop did a good job in replacing the cables or not.
I thought that there would be a schraeder valve under the seat. An old Raceface video said put pressure at 20-40psi. Anyway, when I removed the seat, there was definitely no valve.
So really, I don't even know exactly what model this Raceface is. I understand they merely license others' designs. Moreover, I can only find lame installation pamphlet online. No information about servicing, and definitely nothing of spare/service parts or any way to work on these.
1) what model is this?
2) is there any source of technical service documents
3) any source of technical service parts if necessary?
4) ideas why the shifting lever action sucks so bad
5) ideas how to solve the slow up-move of the dropper
