i know fuck all about downhill bikes. what exactly is the point in having such a complicated gearbox? i get that it gives more clearance, but does it really need to be that complicated. just looks really heavy to me. i guess heavy is good for going hills.

In principle, a G-Boxx system has the advantage of eliminating many common problems associated with a derailleur based system. Since the drivetrain components of a typical bicycles are all exposed and attached as separate parts to the frame they are exposed to the elements, dirt, water, etc. This causes the excellent efficiency of a derailleur drivetrain to deteriorate over time, which in turn means that you spend more time overcoming this inefficiency than providing forward momentum. Of course, debris, rocks and other similar elements may also cause considerable damage to the drivetrain, making the entire system inoperable. Finally, a derailleur based system also utilizes some form of chain tension device in order to prevent the chain from derailing when moving it from one cog set to a lower. G-Boxx provides a unique, simple and clean solution to all of these problems by enclosing all drivetrain based components inside an encapsulated system. This allows the efficiency of the G-Boxx to remain constant and provide the rider with constant and continuous forward momentum.
