I bought a new Whyte bike today and travelled a considerable distance to collect it. (They wont post Whyte bikes and I got a good deal from thae store)
Annoyingly it hadn't been checked over when I arrived and the mechanic had to spend a considerable period of time trying to stop the seat post from sticking on the way back up.
When I got home however it started sticking again.
Is this a common problem?
Can any bike shop which sells Whyte or Reverb seat posts fix this under warranty? I'm not travelling nearly 200 miles each way to take it back again
The mechanic seemed to think it was something to do with the cable twisting inside the bike and being unable to puch it back up due to the twisted cables?
Also, the post doesn't need lubricated, that was queried at the time.
Thanks

Try slackening the pinch bolt just a gnats, worked for me anyway.
Carbon assembly paste on the post and a not too tight clamp can sort that out sometimes.
The Carbon Assembly Paste stops the post slipping in the frame.
I've seen a problem on a Whyte that had a Reverb that was only fixed by sawing off the Whyte inbuilt clamp thingy and installing a traditional clamp because the Whyte one when done tight enough to actually hold reverb was denting the reverb enough stop it from working properly.
Similar problem with my xfusion one, it seem sensitive to seat clamp tightness - too tight post sticks on the way up, too loose and the post moves
Got the same thing with a Kore post on an Orange. Clamp sits just on the top bushing so needs a fine balance of carbon paste and bolt torque.
At th very least, slacken the bolt off and try it again to prove it.
I proved mine by lowering the post, then pressing the lever, once it stuck, loosened the bolt a little while holding the lever until "thunk", the post moved freely. At least then you know what it is.
As mentioned above its probably the seat clamp causing interference.....hopefully

If the Mechanic did say this, he is hopeless as Reverbs don't have cables!
Most likely is the seat clamp as above, but also worth investing in some Widers and Sodstrom Suspension Lube for forks and posts, helps clean the seals and lengthens service intervals too.
