Product Description

Enjoying the benefits of a dropper seat post isn’t just for the elites. The RSP Plummet Remote Dropper Seat Post brings the joys of dropper posts to a more accessible price point.

The RSP features 125mm of drop with infinite adjustability. It is an air-free design with a hydraulic damping. It is cable operated with a handlebar mounted remote. The remote can be attached to either side of the handlebar to cater for every setup preference.

The RSP Plummet is available in both 30.9mm and 31.6mm diameter and has a dual bolt inline saddle clamp, making it easy to get the saddle in the perfect position. The Plummet has external routing, so doesn’t need a frame with internal routing to be used.

  • 125mm drop with infinite adjustability
  • Air free design
  • Hydraulically damped

    I mean it’s a good budget post
    by Dan D on 26/06/2020

    I have had this for about 2 weeks and I needs cleaning and regressing after every ride. I mean every ride. If you ride your bike to a mates house when u get home it will probably need more It just gets a bit slow otherwise and can get stuck. I have found that removing the pointless seal actually prevents more dirt from entering than having it on. All in all excellent value for money and I am going to keep using it.

    Premature Failure
    by Anonymous user on 12/05/2020

    Similar to the majority of reviews on this product the post worked OK for a short time (2/3 rides). The initial problem was the post dropping on its own when riding. If plenty of slack was left in the cable it would stay up with weight on the seat. When using the dropper post it would never return back to the correct height. After 24 months, not that many rides and proper maintenance the dropper post has finally 'dropped' for good. I have dismantled the unit just out of interest and to be honest the build quality is very poor. I think the moral of the story is when buying a component of this nature you need to invest a few more pounds and buy a reputable make that is built to last and does what it says on the tin!

    Broke after 18 months
    by Anonymous user on 02/01/2020

    Like many others on here, mine gave up 18 months into being used. It's like the lever is always being pressed, it won't stay up with any weight on it, and when you lift off the saddle it'll lift to where you don't want it to be. I thought it was a bit of a bargain, but I'm now having to spend more money to replace it as it's not serviceable.

    Poor warranty
    by Anonymous user on 27/03/2019

    I would advise anyone who claims a replacement under the 12 month warranty actually requests a refund at the outset. Then if you want to give it another go by all means buy another...at least the warranty will reset then. My first post failed in 10 months, the replacement failed 3 months later. No refund was given.

    Broke after 18 months
    by Anonymous user on 05/01/2019

    Worked nicely, while it worked. Thumb control could be easily upgraded.. Unfortunately mine seized up. Dust in the carriage actuator button, so that it would not pop back up despite all efforts. Asked Raleigh for a service manual, but there isn't one. They could not help. Probably my fault for riding in wet and muddy conditions 😢 ha ha

    Update
    by Chris D on 10/11/2018

    After 15 months and fairly minimal use this has failed. I removed the cable to replace it, as I thought this was the issue. I discovered that the piston in the top of the unit, which is actuated by the remote in order to lower and raise the post, is loose. The post now behaves like the remote lever is fully depressed all the time. It is up when no weight is on it and goes down when sat on. The unit is not serviceable and so it can only be thrown away. I would not buy another one of these. Better to buy a good, reliable, serviceable one for two or three times the price than having to buy a new "cheap" one every year or two.

    18 month review
    by Anonymous user on 03/10/2018

    Had this post for 18 months now and it's finally given up the ghost. I had been impressed by the quality and price up to this point. It's a shame that everything is press fit because you can't actually service it, or fix it without causing more damage. The remote lever broke about 6 months ago and has been pretty slack since fitting (sideways slop, not cable tension) I installed a bush which helped. Now the post won't lock out because the internal mechanism has blown apart somehow. Unfortunately it's outside of the the 12 months warranty so I have to decide whether to replace with the same or upgrade, but how much can I justify spending on a bloody seat post! My advice is probably to buy it, and if you get past 18 months every month is a bonus!

    Works great but bushing came out
    by Anonymous user on 20/06/2018

    At the time of writing this review, I have had the dropper post for about two months. It was really easy to fit and it works quite well. I really have to push myself down to get the post to go all the way down, but I suspect that I am a bit lighter than the target market. Recently the bushing has come out of where it’s meant to be. I suppose that this just means that mud can get in, so I just have to look after it. All in all tho, this is a great product for the price and I recommend it to anyone who wants a dropper post but doesn’t want to spend too much money.

    Long term review
    by Anonymous user on 04/06/2018

    I've had this dropper post for 18 months now and as a whole it's been great. The dropper itself has been flawless and I can't fault it. However... The problem I have is with the lever design, which I've always thought let the whole product down as its been loose and cheap since the beginning. The design and way it pivots has over time pinched and worn through the inner cable, which is now fraying and on it's way out. To make things worse the tiny grub screw that locks the cable has rusted into place and rounded off on the inside, so I will have to replace the lever and cable. RSP now offer replacement levers but with the same cheap design, so you'd be replacing it again for the same issues at £18 a pop (+ cable). I still think the dropper post is decent and works very well for me, but the lever could be greatly improved and would be a good deal, even if it put the price up a tenner or so!

    Seatposts Guide

    What are seatposts?

    The seatpost is the extendable metal rod that slots into your bike’s frame, with a clamp at the top to hold your saddle.

    Who needs a seatpost?

    Every bike has a seatpost, but a common reason for fitting a new one is to get a longer post for a leggy rider. Weight saving is another prime reason for upgrading.

    What are the choices?

    You need to pick the right seatpost width for your frame, but then you will have a choice of materials, from practical aluminium to weight-saving carbon. Mountain bikers can also opt for dropper posts, which are tremendously useful out on the trails.

    What should I buy with them?

    You might need a different seatpost clamp to go with your new seatpost and hold it firm in your frame.

    Anything else?

    Finding out which seatpost width you need can be a tricky business. With luck it will be stamped on the inside of your bike’s seat tube. It is measured down to tenths of millimetres, so eyeballing it with the tape measure won’t work.
