Very good value, very adjustable, adding bar tape

Fitted these to my mountain bike for long road trips. They're very adjustable and I love the fact that the arm rests are adjustable independently of the bars. I set them up according to the excellent video, then took an allen key with me out on a ride. I found I needed to move the arm rest pads outward one notch for comfort. Very pleased with these for the price. The metal spacers have serrations on both sides, which give good grip, but WILL leave marks on your handlebars. That didn't bother me on a 10-year-old MTB. But if it was on an expensive bike, I'd swap those out for something rubbery, or put a piece of old inner tube inside first. I rode a 55 mile route yesterday and was on these for 95% of the time. One of my hands slipped off once when I went over a bump, so I'm going to put some bar grip tape on the ends for comfort and safety. They do the job well and they're a good price.

Why use extenders in a triathlon?

So you can become a real triathlete of course! That could have been the answer for this emblematic product, but we offer you another approach. On smooth routes, we recommend opting for extenders so you can vary your position as well as improve efficiency as soon as you find the right adjustment and you can hold this position for a long time.

How to find the right position with the extenders

Your position should be as natural as possible, even if you have to make an effort to relax into it to start with (shoulders and neck). We recommend finding an adjustment that allows you to have your elbows resting on the arm rests with a 90° angle between the arm and the forearm. Your hand should fall naturally on the end of the bars for a natural grip. You will probably have to bring your saddle forward on its clamp and perhaps shorten your stem.

Are extenders allowed in the triathlon?

Extenders are authorized in triathlons when drafting (cycling while sheltered by another triathlete) is forbidden. We advise checking the regulations for your race, which generally specify this. As a general rule, extenders are forbidden for short-distance triathlons (super sprints, sprints) and authorized for middle to long-distance triathlons (from Olympic distances).

What level do you need to have to use extenders?

No particular level, quite the opposite in fact! We especially recommend finding the adjustment that lets you use your extenders over prolonged periods without worrying about aches. Consequently, you will gain in speed or reduce fatigue so you can take on the running portion in the best possible conditions.
