This is for sale as I’ve swapped to a Fox Transfer. The upper slidey bit is unmarked and the action works fine with no sinking into the travel.
31.6 size, 150mm travel, internal routing, bar remote included (although I bought one of the ZTTO ones off eBay to use with it – those are excellent in case you were wondering).
Downside – and this is really weird – when it is used in the dry, it works very well. When used in very wet / muddy / Welsh weather, it can be slow to return. I have dribbled some fork lube down under the collar and that seems to have helped, but it probably needs a proper clean/service.
£70 posted to reflect that.
