See title!
Although it feels a little fragile... Good for the price.
The derailleur broke near the hangar bolt whilst riding mid corner. It immediately caught in the chain and cassette causing the back wheel to lock, causing me to crash the bike. I get the bike maintained at Decathlon and the cassette, chain, front and rear derailleur were replaced less than 6 months ago, and I have done no more than 350 miles mostly on road during the lock-down. I see that another customer reported a break in the same place. This item is dangerously under-engineered and should be pulled from the shelves.
A sudden clean break of the arm next to the hanger bolt when changing between mid-range gears. I was not using great force on the pedals, and there were no signs of anything jamming. Was it metal fatigue?
Precise shifting but on heavy side . No complain for the price. Use on my mtb 1x10 40t

V popisu je 42 zubů převodů, ale po dodání jsem to namontoval na kolo a 42 zubů to opravdu nezvládá, v popisu maximálně 40 zubů. Ihned jdu reklamovat a mám sto chutí vás nahlásit za klamání zákazníka. Naprostí amatéři. Na které se nedá spolehnout
Dobrý den, Jakube,
velice děkujeme za Váš čas věnovaný recenzi tohoto produktu. Každá zkušenost je velmi cenná a pomáhá nám s vývojem nových modelů.
Je nám líto, že produkt neodpovídá udaným parametrům. Spojili jsme se s kolegy z oddělení cyklistiky a tento měnič je opravdu na 40 zubů. Bohužel, jedná se o chybu na webu, kterou jsme předali kolegům k opravě.
Ráda bych Vás proto pozvala na Vaši nejbližší prodejnu Decathlon, kde můžete produkt vrátit či vyměnit za jiný.
Omlouváme se za komplikace.
S láskou ke sportu,
Barbora
Un buen cambio de 10v fácil de ajustar y compatible con mandos Shimano, en mi caso el piñón fue de 11*36 y aún le queda para subir, funciona muy suave, lo recomiendo, saludos.
De momento perfecto. Ya veremos como envejece
Par contre mon fils a fait une erreur pour 1 virement il a fait le versement sur 1 référence de commande et il n a pas encore reçu le remboursement et cela fait 1 mois
Ce dérailleur est compatible avec les groupes 10 vitesses shimano d'après 2015 soit pour le groupe tiagra 4700 seulement, Contrairement à ce que le service D4 m'ait répondu

Monté sur mon vélo taf avec la manette ad hoc decathlon, et ça marche bien pour le prix. Monté avec une cassette 11/40.
Peu utilisé depuis le changement
