Ive just been reading an Orange Bikes magazine and i noticed if you buy one of Oranges bikes you have the option of getting a Chain Device installed.
"We're now offering the Gamut Dual as an accessory when you purchase an Alpine 160"
now i don't know if its just for the alpine 160 or you can use it on a normal 5. Ive never used a chain device before but people say it keeps your chain where it should be so it doesn't jump gears etc, is it worth getting one if i was to buy one of the new orange bikes ? thx
