About the Gravity Zilla AL PRO Gravel Bike
The Gravity Zilla AL PRO is an aluminum gravel bike built for bikepacking and all-road riding, with a full carbon fork, a Shimano GRX 2x11 drivetrain and GRX400 hydraulic disc brakes. It comes with a dropper post and clipless pedals included, plus mounts for a top-tube bag, triple fork cargo and a rear rack. Owners describe it as a well-rounded, lighter-than-expected budget gravel bike that handles commuting, errands and long weekend rides. The trade-off is that it arrives about 90% assembled, so expect to adjust brakes, shifters and derailleurs before the first real ride.
