I got one – second hand – and tbh was worried about the reputation of the earlier versions.
So far its been faultless. And I really like it! Main differences for me are the smoothness and the climbing traction. I got one volume adjuster thingy in there – and now that its set up – I just leave it as is.
I recently bought the optional ‘OPT’ remote : and while its useful (set the climb switch anywhere from 0 – 100%) – but god its ugly! And those things that look like cable adjusters – are not! And the install at the remote end is also a pita. And it uses brake cable ffs!
Negatives –
: there seems to be little info on diy servicing.
: the shock mounting hardware will probably be different to what’s on your frame already.
: installing the remote (as above)
: do not EVER attempt to set sag with the pump attached to the air valve. The shock compresses and interferes with the valve stem and cracks the stem – or possibly the body!
