After the narrow-wide revolution matched the clutch system shifters, there were rumors that the chainguide era is over. Innovations known by the worlds best racers were officially affordable to the „average Joes” who don’t need that extra safety during weekend rides, right? Well, after many post ride talks with the actual users of the new systems, we knew they are not enough. That’s how we came up with Piano – chainguide that matches front shifter mounts! With slim design and race ready guide, Piano practically covers up to 100% of the fall issues from the top of the chainring.
Our goal was to make a construction with a perfect balance between weight and strength. As the first in the world, we have introduced a special composite that allowed us to reduce the weight to the minimum while maintaining the field proofed stiffness and durability. Lightness of the construction was achieved by using a ribbed pattern of the mold, which resulted in less usage of the material. In the addition to the chainguide you will get a set of guide plates with which you can use an oval chainring. The material used in their production is very sleek but robust enough to take a beating!
Piano chainguide is available in two different options – compatible with S3/e-type mounts or High Direct Mount. It weight’s only 25 grams and with an attached set of spacers, you can adjust your chain line anywhere between 48,5 to 51,5mm!
New product of Mozartt.com will not only suit enduro bikes but will also fit into the less aggressive types of riding like: XC, AM or even Cyclocross!
