  • System EX Adjustable Stem

    The System EX Adjustable Stem is wonderfully impressive with its powers to adjust from a zero degree rise through to a 60 degrees rise. The stem gets you riding in the right position for you and with cold forged and heat treated aluminium power, you can enjoy it for a very long time.

    Rated 5 out of 5 by System EX adjustable stem Does exactly what I wanted it for, raised the bars and brought them nearer to the seat. easy to fit and adjust. Staff at Beverley really helpful. 17 October 2016
    Rated 5 out of 5 by Worthwhile addition My Carrera Vulcan handlebars were too low for my liking - too much weight on my wrists. This solved the problem and gives a good range of positions. It is heavier than the replaced stem but not much. I was, and still am, unsure what the 110mm size means. They come in a range of lengths and I just guessed. Maybe Halfords should look at their description to make it more helpful. 23 August 2016
    Rated 5 out of 5 by Just What I Needed Adding this stem adjuster completely transformed the dynamics and comfort of my bike. 09 August 2016
    Rated 5 out of 5 by Good Value, adjustable Stem Easy to order, advised when ready to collect; polite service in store. Stem is easy to fit, and also to adjust. take your tools with you on your first ride, just in case. I need to be able to increase the height of the handlebars, this has been achieved. 09 August 2016
    Rated 4 out of 5 by did the job Bike was sliughtly too long causing shoulder and neck ake, fitting this brought the handles bar closser and higher resolving the issue. It would help if halfords carrera road bike had narrow handle bar as this is 2" wider than most! 03 August 2016
    Rated 5 out of 5 by Perfect for the intended job Bought two of these for our bikes hybrid to raise the bars to a more comfortable riding position and it seems to have done the job well. Time will tell of course but so far it seems to have achieved the intended aims. Had them fitted by Halfords for free during the first annual service. The ladies Carrera crossover 2 needed no alteration to the cables but my gents one needed a new outer cable for the front brake when extended to the full 60 degrees. I liked the fact that they were all black as well which matched the original fittings and chose them after reading many positive reviews at Halfords for this product and the price was excellent when ordered online for delivery to the shop that was doing the service. 31 July 2016
    Rated 4 out of 5 by Good but not fantastic. I fitted this stem and it's OK but it's not fantastic I have it adjusted to 30° and it does flex a little when you are climbing out the saddle. That's why I haven't given it full marks. What I have actually done is now I have found the angle I want is buy a fixed stem and the adjustable is going on my wife's bike and we will probably buy her a fixed stem once she has decided what angle she wants. But for what it cost that's fine. 20 July 2016
    Rated 4 out of 5 by Make Sure It's Tight! The stem does what it says on the box, if a little heavy - just make sur that the rachet nut is very tight. I thought it to be tight but it worked loose and caused a bit of a fuss! 04 July 2016
