A few days ago the folks at Grand Pitstop sent me a GRoller to review.
The GRoller is a portable tool that helps you maintain your motorcycle chain and wheel. It is specially helpful for motorcycles that do not have a center stand. It is a small and portable product that you can carry in your tool kit. GRoller can support motorcycles up to 300 kgs.
The motorcycle wheel rests and freely moves on two rotating rollers. There is a smaller fixed roller that helps you get the wheel up to the two rotating rollers. The bottom plate has two rubber strips that prevent the GRoller from slipping on the ground.
