Ok, just some initial feedback – I've onyl taken it for a spin in the street…
The Good:
It looks quite reasonable – it's no Joplin but on the other end of the spectrum, it's not Gravity Dropper! 😉
Rotational play is as good as non-existant.
Those worried about the 20mm of 'suspension', this only works when it's dropped – if it's at full height it is totally locked out. I don't intend to be sitting on the saddle in situations when it warrants dropping anyway.
Now the not so good. Yeah it's heavy. Although once on the bike it wasn't actually that noticeable.
I actually thought mine was faulty at first, it just wouldn't go down when I sat on it! If I removed it and put it on the floor it would compress easily. I left it compressed over night and then tried again, still no joy, emailed Leisure lakes to complain. In the mean time, faffed some more and realised you do need to shimmy forward slightly and it just works. An odd quirk but given the price and/or availability of other 27.2 posts, I can live with it.
Which so far, kinda sums the post up – I don't intend to run it full time, and for the money, I can live with the downsides.
I don't know how it'll hold up in the wet because I don't intend to use it in the wet. When we get some dry weather, I'll have a play in the woods and report back.
