In Australia … NO MUD !
On my 4th KS i900 , they are a piece of crap !
The place i bought it keeps replacing it on warranty , so i just have to humour them .
Gets the gouges in the back to start with then starts jamming up or down …. then starts creepig down . I would have dumped it 9 months ago if it were not for the replacments .
Can only comment on the Crank Bros joplin i had before this one (only changed as new bike had different sized post) , it had a slight lateral play … but it functioned perfectly for 18 months.
BTW the 4th KSi900 now has gouges …. i'll give it 2-3 weeks then its sent back too. The shop does not sell them anymore so hopefully i'll get a credit note , then ill prob go back to CB or Gravity dropper.
