Knockout Frame: Gravity Knockout Fat Bike Frame and Fork

Description:  Gravity Knockout Fat Bike Frame and Fork


Okay, here's your chance to build a fatbike on a budget. There is a small rub though....and it's an actual rub. Once built the chain rubs the inside of the drive side dropout when on the smallest cog on a 8 speed cassette. This is a factory design flaw that can be fixed by adjusting your limiting screw so the chain can't go into the smallest cog or you could build it up as a single speed or you could do something else we have not thought of.


Will not fit a 4 inch tire, the knobbies will rub the frame.


This frame has a factory warranty against defects but the chain clearence issue will be excluded.


Frame may have minor scratches or scuffs!
