Very good product. Reasonably priced.
This is excellent product,the build quality and finish is excellent, B'twin accessories and parts fit precisely like a glove.
Well designed and sturdy product. My backache problem gone instantly after using the product on my Montra Helicon
After suffering with backache due to the handlebars being too low I invested in a adjustable aheadset and have been reaping the benefit since. It has made a huge difference to my riding comfort and enjoyment without having to lengthen brake and gear cables.
Very well guided by the staff
Stem is shaking like anything, even after tightening it very tightly it I'm unable to stop it from moving. Even tried adjusting it from a Bike store. Still the same, I couldn't find any replacement for this.
Thanks for taking time out to review this product. We regret the negative experience you have had with this adjustable stem. The shaking of the stem could be due to the disparity between the handlebar size and the stem or the steerer tube. It could also be to due to a defect in this particular piece that you have purchased. We advise you to take the stem along with your cycle to the nearest Decathlon store for the Workshop technical team at the workshop to give you a solution. If the product is defective we will provide you an exchange.
Very simple to install onto a RockRider 560. I used a 5mm hex bit and an electric screwdriver to screw to the correct torque. Well made and works great!
Search no more. This is the perfect product to increase the handlebar height and minimise the reach. I fitted it on to my Cannondale and I never had such a comfortable ride ever. It will make you want to ride your bike more.
i have had nothing but problems with this stem i have torqued all the bolts to the required level but there's still a lot of movement in the stem that feels unsafe tried different angles etc but no joy so have had to take off the bike.
Sorry to hear that your experience with this product hasn't been as you'd expected. I've fitted a few of these and not had any play within the stem. I'd suggest you take the item back for a return.

Great product and fitted by a courteous and proficient assistant.
Easy to Install. It fit my SCOTT Hybrid.
I bought this adjustable stem because I've been having trouble getting down on the drops on my road bike, hardly ever used them because I find it uncomfortable, (I'm getting old!!), solved the problem with this stem, raised the bars enough to make using the drops comfortable again. Very useful item, would recommend to anyone who struggles using their drop bars.
I am a time trial cyclist. Getting in position is a pain the butt. Buy one of these stems and you can mess with your position until you've got what you want. Then you can buy what suits.... Word
Simple to use and gives a good range of adjustment
