>>1701101I had a 3 by and it's normally quite good, great range but sometimes when I tried to go down in gears on the 3by before a hill on the trails the chain fell off on the inside, it was like 3 times I think over one year.
Now instead of 11-36 on the back and 22-32-42 on the front i'm with 11-40 and 30 on the front and besides having to drop and up a lot of the gears the chain hasn't dropped yet.
Woulnd't waste money changing it though, I'd rather, if had to improve on that current bike, get better breaks.
