80mm stem

Works a treat for me. My LBS would have charged 3 times as much for a similar product. This is why I go back to Decathalon.

Shortens the reach of a full-out position

I bought a Alur 700 and was a bit stretched out on the hoods on th supplied 100mm stem. I was advised that a simple change of stem would make the bike far more comfortable - and it did. Whether this is true 'race monkey' rules, I don't know, but I can cycle further on the bike in comfort! Easy to change, following the video on the website although mine came with silvered bolts - which I swapped out for the ones on the 100mm stem for the black ones to complete 'the look'

Alles in Ordung

Der Vorbau macht was er soll, ist sauber verarbeitet, und lies sich leicht montieren. Ich sitze tatsächlich etwas besser auf dem Rad. Hinweis an Decathlon: Es handelt sich ja nicht um ein Leichtbau-Teil, dennoch fehlen die Freigaben für das Einsatzgebiet.

Muy buena para el precio

Estéticamente está muy discreta y bastante sólida, un poco pesada, pero por el precio, está más que bien
