A little difficult to fit but luckily I have a besite who knows how to do it. Ok for an everyday cheaper derailleur.

I am a Professional Bike Mechanic and I needed a reasonable priced long cage rear mech which was Shimano compatible. I had not purchased one and called into Decathlon on my way past to get some cycle kit. I picked one of these units up for the repair I had to do on a Raleigh Ladies Mountain Bike..... The Mech fitted with no issues at all aside of setting up the low and high limit screws as this was being fitted to a 7 speed freewheel. The bike was fitted with the awful grip shifts and with this unit it works 100%... so a cheap and great replacement for O.E equipment

The new VFM monster RD for wide range cassettes!

Installed on a 1 x 8 drive train featuring a Sunrace 11-40T 8 speed cassette and paired it with the BTWin 8 speed grip shifter as well. What can i say? With the included road link with the Sunrace, this humble RD shifts to the 40T cog and back buttery smooth and with the security of a fat, thick and strong 8 speed chain! Best VFM (Value For Money) combo (RD + Shifter) for me for this application - thanks a lot Decathlon! Also your technical staff in store were patient and professional - cheers ^^

Hi John,

We are glad that you are satisfied with your purchase of the 7 to 9 speed Rear Derailleur. If you are looking for more serious speed in the future, you can even consider getting a 9 or 10 speed system which is also available in our stores! Our components are all compatible with the Shimano gearing systems so you will have no issues with mixing them.

The Btwin components are also installed on our mid range bicycles that are available in store and we have had no complains for them so far! They are value for money and they significantly reduce the cost of our bikes making it more affordable for the many.

Thank you for our purchase and we hope to see you again soon! :)

Das Schaltwerk hat an meinem Stadtrad das 8-fach Deore Schaltwerk ersetzt. Für den Anspruch ist das Preis-Leistungs-Verhältnis unschlagbar, gut eingestellt schaltet es sehr sauber und direkt.
Preisgünstiges Schaltwerk

Habe als Ersatz für ein defektes Shimano-Billigschaltwerk Ersatz gesucht und bei BTWIN gefunden. Wenn das Billigfahrrad damit noch zwei Jahre auskommt ist es meiner Tochter ohnehin entwachsen. Der Einbau ging erfreulich einfach.
