Just what I needed

This make riding my MTB so much better, I was advised by somebody else that it would be a bad idea as it would make my steering slow! I don't know what they meant, it doesn't seem to have affected that & it make the ride far more comfortable & enjoyable. Easy to fit it too less than 10 minutes.

Useless Advice from Staff

I was assured by Decathlon staff, this would fit my Rockrider 300 stem, since I'd read on the net, this stem needed an additional shim to fit correctly. I even pointed out the same bike on display in the shop to the staff, to make sure. Yes, yes of course it will fit, they insisted. When I arrived home and tried to fit it on my bike - guess what... My fault for assuming the bike staff at Decathlon had the remotest clue.

Dear Sir,
I'm sorry to read that you did not receive the correct advice regarding this stem.
I will contact the store and try to discover why this was the case.
Please feel free to return the item to us for a refund or exchange.
Once again, please accept our apologies for the advice you were given.

solved the problem

I had a problem of posture on my MTB, but it solved the problem all together also it is very easy to install, overall an excellent product.

For Road Bike Think Twice

I bought this for my road bike coz of the discription for MTB or road bike. The quality and fit of the stem is good. But the stability of the same on a road bike is bad I lost control and fell in the first ride itself. It's good for MTB and hybrid.but ppl buying for road bike pls rethink. Planing to change my tires from 25 to 28m to see if it gives more control. Will update my review after tht.

maximálně spokojen s výrobky i obsluhou

Er ist gut geeignet z.B. für ein MTB, das als Alltags - oder Pendlerrad genutzt wird. Durch diesen Vorbau erreicht man eine aufrechtere ,bequemere und vor allem auch eine übersichtlichere Sitzposition. Einfache und schnelle Montage möglich. Die Anzugswerte der Schrauben sind aufgedruckt und sollten mit einem Drehmoment-Schlüssel (wenn vorhanden) angezogen werden. Er verfügt zudem über eine 4-Schraub-Lenkerklemmung und ist absolut sauber verarbeitet.

Leichte Montage

Sehr gute Lenkervorbau leicht zu montieren und guter Preis


die Montage gegen sehr schnell passt perfekt und tut was es soll.

Top Spacer!

Habe die Spacer für den Austausch des Standard Vorbau beim Decathlon Mountainbike Rockrider 520 benötigt. Hat perfekt funktioniert!

Alles bestens
