I bought this devinci troy carbon of a work colleague last year for £500 and he has already done a huge amount of work too it like putting in new middle and front suspension and replacing preakpads. At this point I was and still am in the range of alright to intermediate at repairs on it so far all I have had to do too it is refill the brakes and replace pedals. But recently as it has been winter and where I live it's too boggy to ride anywhere in winter time I am now only just getting it out and serviced by myself again. But recently I have noticed that the dropper post has been sticky, so when I press on the lever on my handle bars it only raises to halfway up I have tried using wd40 and has helped slightly. So overall I am wondering if anyone has got any knowledge and advice I could have on what needs to be done too operatelike normal agiain. Thankyou💪

It would be very helpfull to tell which droppeer post do you have.
But nowadays most of the droppers have the closed cartridge inside, and usually this one needs to be changed.
But before that i would check if everything is ok with cable and actuator.
Wd-40 is not the right thing in general. It is a fully evaporating cleaner / de-greaser. Its lubricating ability Is very short-lived.
One thing that can make a dropper stick in the winter time somewhere mucky and gray and wet… On the bottom of the post is a tiny lever actuated by the cable. I have found that it can get gunked up with water and get quite sticky. Undo the droppers switch from the handlebars so it can move freely, remove the dropper part way from the bike so you can access the switch. You don’t need to disconnect the cable. Then clean the switch, and dollop it and work it with grease.
Sometimes droppers also just work slowly when they get really cold. Different brands in different ways.
First off, WD40 is not meant for applications like a bike dropper post. WD40 is petroleum based and may not play nice with the seals. Before you just start spraying random chemicals on your bike, you need to do some research.
Secondly, we can’t help and provide advice, when your post doesn’t include any helpful or relevant information. What model dropper would be a great piece of information.
Figure out what dropper you have, read the manual for any procedures on bleeding, servicing, or adding pressure. Or, take your bike to a shop and have them service your dropper. In some cases it may be more cost effective to just find a new dropper that’s on sale, vs having yours rebuilt.
Slick honey is the product you want for seat posts. Also check the air pressure. Some posts don’t do well in cold temperatures. If all else fails, you will need to rebuild it. Manufactures like OneUp offer rebuild kits.
I use fork lube on my dropper post, just put some on the post and cycle it a few times then wipe of the excess as it will attract dirt, works fine for a few rides.
Get some specific mtb lube. Clean and lube after every ride. I do this with dropper post and my forks after every ride.
What’s the brand? They should have a service guide online.
Uh, have you checked the air pressure?
A few tips:
* Add more air pressure if it has a Schrader valve (under the seat).
* Apply proper grease under the collar. Stop using WD40.
* Don’t overtighten the seat clamp.
* If it’s a Rockshox Reverb, it’s already working as intended (i.e it’s trash)
Check the pressure.
my dropper has been stuck in position after I over tightened it try loosening it at the seat post clamp before anything
Damn you called him a work colleague not friend after he sold you this bike for £500 cold lol
NEVER USE WD40.
Things to check:
Make sure the cable is tight and fully pulling the actuator.
Check for friction in the cable.
Make sure the seatpost clamp isn’t too tight.
Using a SHOCK PUMP, make sure pressure is 250-300 psi (this should be right for oneup, may vary for other droppers.
Follow the manual to clean and degrease the dropper post. This is the most common thing with oneup v2 posts, they get sticky and need new suspension grease such as slick honey or seam butter.
On mine, I have found the rubber boot collects dirt gently clean and lube post
Pull up the manual from the manufacturer, disassemble, clean, grease with some slick honey and take it back out. It should take you 20 minutes.
Use Slick Honey to lube the post. Another thing to check if how tight then seat clamp is. It might be too tight.
