Tri Bars

Since I've fitted these for bars I have completed 3 x 100 Mile rides they are really comfortable and were really easy to fit with the added bonus they were relatively cheep I'm really happy with them 😁

A bit tricky to fit but Decathlon member of staff helped and it only took 3mins. Huge thanks. Good value extender.

Happy with purchase

Came across this in the store and got tempted to try it. I am not a TT maniac obsessed by speed gain but more an endurance rider interested by an additional posture possibility to relieve the pins and needles I get in my hands. Was a bit apprehensive I would not manage to fit it as I have all my brakes and speed cables very close to the handlebar but managed to sneak it in. Also I have a 32mm diameter Giant handlebar so I did not need the diameters reducers and the main parts had not spline, but once tighten enough onto the handlebar it's quite sturdy. I have ridden a several hundred miles since, no problem, I check regularly that it stays properly fastened and it does not get loose despite all the potholes on our British roads. As other have mentioned yes, nuts are very greasy but so what? The main adapters between handlebar and extender have only a screw and nut on one side but I did not feel that the 'hooking' system on the other side was weak or fragile. the whole looks solid enough to me I trust that by installing this extender you're meant to loose the normal position on the handlebar and only have the gear shifter as an alternative hand position. By installing the elbow rest as far inwards as possible (position still comfy) I managed to saw off at least 1 inch of the tube they're screwed onto and have therefore retrieve enough space for my hand on the default handlebar position. So with 3 choices shifters/handlebar/extender I can alternate my hand positions and keep pins and needles at bay more easily. Riding while on this extender surely does give you a bit of extra speed and also some welcome change of position for your back. Got used to it pretty quickly, not as difficult to steer the bike as I thought it would (obviously not intended for cornering) and overall feeling more secure than I expected. In short, very happy with it.

Great value bar

saw these and couldn't miss them at the price. quick and easy to fit with the few correct tools. haven't been able to properly test them yet as I'm recovering from a ruptured Achilles but hope to get out again in the next few weeks

Comfortable and cheap

Tried these after I felt uncomfortable on straight tri bars. Immediately felt safer and more comfortable with these and all for under ÂŁ20. I use the pads probably more than I do the handlebars when touring!

Value for money but gets loose after a bumpy ride

Positives - Comfortable, Economic, Easy and quick installation Negatives - Gets loose after a bumpy ride, the colour scratches off easily

Needs Improvement

The Trialthon Handlebar Arm rest .One of the connectors did not have a bolt and nut. I did not check, nor it was verified by the person making the Bill. The Price tag mentioned in the display area was showing higher price than the actual price Since I have bought the product at Bangalore stores, I cannot go back there to get this matter sorted out...

Hello Prashant,

Thank you for your feedback. The product that you have purchased sounds defective. You can get it exchanged at any decathlon store. It does not have to be in Bangalore. The price displayed in the store will always be equal to or less than what is printed on the product.

Verwende das Teil auf einem Cross-Bike, passt auch hier. Montage etwas fummelig, jedoch kein echtes Problem. Bietet alternative Sitz/Tretposition, entspannt Arme/RĂŒcken, reduziert Luftwiderstand deutlich, fĂŒr mich sehr bequem und effizient.

Super Teil

nur fĂŒr SparfĂŒchse

Vielleicht etwas fĂŒr Einsteiger, die es gerne etwas Komfortabler haben. Teilweise auch fĂŒr Bikepacker geeignet, durch die bequeme haltung auf dem Lenker. Zu beachten sind sie limitierten Einstellmöglichkeiten. Ausserdem schrammt man sich die Arme auch mal gerne an den Auflagen wenn man normal den Lenke bei einem Rennrad greift.

Guten Produkt!!!!

Bin sehr zufrieden.

Perfekt fĂŒr das Geld

Ich tausche den Lenker regelmĂ€ĂŸig gegen einen KlickFix-Adapter. Die Montage dauert keine fĂŒnf Minuten und das hĂ€ufige Wechseln schadet ihm nicht. Nach ca. 1500km und einem Sprint-Triathlon muss ich sagen, dass das ein prima Kauf war!
