interesting to hear you rate the KS above the GD, most of what i read is very much the other way round
After initial problems with the KS (loose head, and gouges to the post) its been pretty much faultless, and the lever is a nice shape and just works, smoothly and with little pressure. The uppy downy bit, is smooth and you don’t have to double tap the saddle to get it to move. All in all, I’ve found it to be a fit and forget item (after the initial problems).
GD, I have/had the 3 position one, (1″ then 4″ drop) and I found it just didn’t work well, even though I stripped it lots and regreased everything, quite a few times
Problems I found were:
1. Boot would unclip letting mud/grit in and then the motion wouldn’t work very well. Cable ties, etc didn’t help.
2. Double tap of the saddle, took a bit of a knack, whereas the KS just goes up or down when you press the lever, and while it did work, when stuff gets steep you don’t want to be arse tapping your saddle trying to get the catch to release.
3. The lever was thin and a bit spindly, and had a bad habit of flexing and then getting stuck on my grips
4. Getting the saddle to work at all 3 heights was a bit of a bastard as soon as mud got past the boot (see point 1), so you had to twist the plastic collar to try and get the sweet spot, but what you normally ended up with its either fully extended, 1″ drop but wouldn’t stick at the full retracted position (it would go down, just not hit the catch, so when you stood up it would spring back up), or fully retracted, 1″ but not fully extended.
Also apparently you aren’t supposed to ride in the 1″ drop for any length of time as the catch isn’t upto much.
The GD was good 5 years ago, however things have moved on.
