Review: Muito bem construído, atende ao que se propõe
Review: J'étais plutôt sceptique en commandant ce produit car j'avais vu sur des précédents commentaires que le montage était ardu et pouvait donner quelques sueurs froides... Néanmoins je me suis quand même décidé à le commander car il n'y a pas d'autres alternatives sérieuses sur le marché. Donc à ma grande surprise le montage s'est révélé d'une simplicité (presque) enfantine. J'ai suivi très scrupuleusement les étapes de la notice en anglais. Il faut juste être vigilant sur les métriques car dans le système anglo-saxon, 1'' (inch) = 2.54 cm. Et aussi prévoir une clé Allen taille 3 et un cutter. Le gros de l'opération consiste à découper un cône en caoutchouc qu'on a préalablement placé et marqué dans la colonne de fourche de la moto. Il faut ajouter un petit débattement de 1/8'' (3mm). Une fois que cela est fait, il faut faire un assemblage avec les pièces idoines et ensuite on insère le tout dans la colonne. Une fois qu'on a bien serré la vis avec la clé Allen, le système continue de tourner ce qui peut sembler déroutant mais en réalité il est conçu comme ça. Il n'y a plus qu'à fixer son smartphone et puis roulez jeunesse ! Le seul point négatif pour moi, je dirais le prix.

*by J***A on 16 November 2015*

This is the simplest stem mount I've seen. It uses an expansion sleeve to hold it in the stem and goes on solid when sized correctly. I like this over others since I can still use my triple clamp front bike stand with it installed. Initially I wasn't in love with how high the phone sits, but I'm used to it now and have it positioned so it's just below my gauge cluster. Had this about a year now, no issues. Had to remove it today to adjust my head bearings. It was a little bit of a pain to reinstall due to the hard rubber compound but, I managed to get it tightened up. Added a picture of it trimmed down to fit my 2014 Yamaha R1 stem.
