As PP states, I beasted mine around the alps for a week, with little problem.
It’s a pretty device (as they should be i suppose) as it just needs to go up and down when I want it to!
Good points are:
It’s dirt cheap compared to the others – there’s no ignoring that fact
It’s one of the only ones that fit my 27.2 bike
It’s got the lever under the seat – i still think it’s the neatest and a very user friendly design.
It’s infinitely adjustable (i.e. can be stopped anywhere along it’s uppy downy length
Bad points:
Not as light as others
Does have a bit of play, perhaps more than Andy’s gravity dropper, but un-noticeable when riding.
Is like an adjustable suspension seatpost i.e. it can bounce up and down about 20mm, but this only happens if you sit on it in the ‘line of travel’. As my seatpost is quite layback, you have to sit abnormally on the nose for the seat to squich down – in normal riding it just doesn’t happen.
Would I reccommend it to a friend – definitely, It’s dirt cheap compared to others and does it’s job well.
I’m gonna attempt to take it apart for a grease and polish, so hopefully no high pressure bolts will burst through my face….
