Mr Wright A huge improvement on the original equipment! Easy to fit, installation instructions are clear. It works perfectly straight out of the box, I didn't even need to adjust the cable. Smooth and swift operation on the trails. So far I am well impressed with this dropper post, especially at the price!
Mr gavin Gamechanger - no matter what MTB bike you have a Dropper Post will improve your flow no end.
Mr Bates Wish I’d bought one sooner
Lorefan Good value easy to install. A little sticky at first but easy to sort and works fine now.
Mr Oldman At this price point you can’t expect too much from a dropper. The product is however sturdy feeling and does it job well. While upright position the post feels rigid. Lowering the post feels a bit tacky, but this might be due to the short time of using it. Good buy!
Anthony This was my first dropper post Easy to install seems well made for the price a good entry leval seat post holds the seat firm and the action is smooth has slight play in the top tube but had already read this on other reviews so no suprise over all very happy
Mr Winsor Great value dropper, can't fault it at this price.
Mr Lewis Great product for the price, really easy to fit. As always great service from Merlin
Mr Thorpe Budget post, easy to fit and ticks all th boxes
joselito Very good quality dropper seat post
Colin I've only used it once, I would have rather waited to review this until I'd used it more, but I'm being nagged here. That said, I now think mountain bikes should have a dropper post fitted as standard, this is probably the best thing I've bought for my bike, I hope it gives me many years of service.
Mr Montgomery Perfect operation
Matt Arnstein Good value entry level dropper post. Cable comes pre-attached so you can just "plug & play" which was a nice touch.
Mr Swain Awesome product, does what it's supposed to, go up and down, easy to install. Happy with the dropper post.
Mr Johnson For the price it is a great dropper post. That being said, it has its flaws. I put mine on a fat bike that I mainly use in the cold winter months. When it is cold, the post can be very slow to get back to position. This post is not as easy to operate as my Fox Transfer, but is also much less expensive. You really need to push HARD to get the post to go all the way down. The first 3.5" of travel goes pretty smoothly with moderate pressure, the final 1.5" is another story. I have to sit on the seat for a prolonged period and really push hard to get it to go all the way down. The remote has some play in it, but works well. Overall it is a very decent dropper post for a very good price. If it lasts for a few seasons it will be well worth the money, even considering its shortfalls.
David Good operation and absence of the lateral movement that can plague dropper posts. Would buy again.
Zac So far so good! Intial impression is good quality. The stansion is well finished and everything worked as it should. Installation was extremely easy the only complaint I have is that one of the bolts to lockdown the seat is right above the cable housing and makes it hard to access. There is very little play in the post about a mm or so from side to side. I have only been on one real ride with it about 20k with varied use and a pretty good fall, with no damages. For the price I'm very pleased.
Oestergaard Nice performance dropper, easy install and ready to ride
Kim This thing rocks. Fit like a glove on my Cannondale. No wiggle or play on this. I wish the trigger on the bars could be angled but I'll get used to it. Hands down the best bang for bucks I've spent. I hope it wears well.
