    Support for my fat bike Dear Monsterbicycles, I would like to thank you guys for bringing in such support items for other brands of fat bike owners. No bike shop would want to touch/service or support my China fat bike. Lucky i found you guys. With this upgrade my fat bike now is much easier to ride and has more lower end power. Thanks again.

    Lim Ethan I just purchased this upgrade for my fat bike. Woah, the difference was like night and day. Highly recommended for all fat bikes. The best upgrade so far. Did I say highly recommended? ;)
