I’ve recently got a dropper post & I usually run a rear mudguard over winter. I’ve a Giant Trance XL which I sometimes put in my car to get places & usually my seatpost mounted mudguards I can loosen & rotate so it fits in my car.

The rear Mudhugger seems to be the popular option but I reckon I’d be unable to get my bike into my car with it on.

I’ve got a rear Crudcatcher & the Lifeline equivalent, but they need to be fitted about half way up my seatpost for them to avoid touching the tyre at full compression, so no good for my 150mm dropper.

Is this any good? as it can be adjusted as fair bit:

Or are any of these or similar any good?:

Thanks for any suggestions.

Old inner tube and cable ties will protect the dropper better than a mudguard. Remove the saddle and slip it over the top then refit saddle and cable tie both ends, obvs this will not keep your arse dry if that’s the idea of the mudguard, personally never used a rear on the mtb so this will probably be of no help but it does work

Convert the rear hugger to quick release with the Velcro straps they supply with the front one. I’ve done my full suss & fatbike & both are solid as a rock but can be removed or mounted in seconds

Cool, thanks both. The inner tube sounds good, I imagined a rear mudguard would be better, good to know. I’m not sure I share your trust in velco, lol! But i think I saw a video somewhere saying it was a particularly strong type, so mibbies! 😀

Edit: oh, I’ve just realised I misunderstood your innertube method, your idea is as per pic in this thread: https://singletrackworld.com/forum/topic/so-what-you-keeping-the-wetdirtmud-etc-off-your-dropper-post-with/

**** that.

Keeps any grit that WILL get in there, in there all the time. The same reason no one does this on shocks and forks any more.

Fit a mudguard.

A better way of using an old tube is to cut a strip about five cm wide and cable tie it to the bottom of the post under the large nut. Then cut two small slits at the top and cable tie these separately to your saddle rails. I keep the length of the tube such that at full post extension, it’s slightly under tension to stop it flopping about. This avoids the crud build up that Nobeer refers to and stops all rear wheel crud.

I use the Shimano version, the 125 will fit a 160mm dropper post fine. Keeps the crap off the most crap prone part of the bike, highly recommend.PS the seals on dropper posts are nowhere as good as fork seals so riding in the current wet weather conditions without one will very quickly shorten your seatpost shelf life.

One of these.

Postfender.scot have some really good ones. Friend has one and works so well

Thanks for all the replies! I’ll probably go with the inner tube on the rear of the post options.

Aren’t they all just the same seals just differing sizes?

I use the inner tube method but only covering the rear of the post so it doesn’t become a filth trap. You can cable tie it to the top of the seatpost and use a velcro wrap tie at the base to make it easier to clean.

Re Speeder, true but there is more play in seatposts and not many with forks equivalent oil wipers

Sigh… 7th ride in with my first dropper; having always run it with an inner tube behind it, and been fastidious in keeping it clean after each ride (though the mudguard has protected it well), and today it has presumably got some dirt in it & it has a slight score up part of the post & it now doesn’t go back up properly. 🙁

It was faultless for 6 and a half rides though.

I have cut down a wet suit sleeve in the past. Found bike inner tubes don’t last long, but have a HD motorbike one on at the moment … so far so good.
