Getting between cassette cogs or around derailleur pulleys with a brush only pushes grime around rather than removing it. The Gear Floss from Finish Line solves that problem with microfiber rope construction that actually captures dirt instead of redistributing it. Each rope features star-shaped grooves that trap grease and particles deep inside the fiber core, pulling contamination out of tight spaces that brushes can't effectively reach.

You get 20 ropes per pack, each measuring 20 inches long. The microfiber material is tear-resistant enough to handle repeated use on metal drivetrain components without fraying or breaking down. Once a rope gets loaded with grime, you can wash it and reuse it. Position the floss between cassette cogs, pull it back and forth a few times, and you'll pull out the buildup that accumulates in those narrow gaps. The same technique works on chainring teeth, derailleur pulley wheels, and around hub flanges where spokes attach.

This works well on brake arms and the bottom bracket shell where the crank spindle passes through the frame. Areas like these collect road spray and chain lube overspray that's difficult to reach with conventional cleaning tools. The flexible rope contours around curved surfaces and threads through restricted spaces. If you're working on bikes regularly or just maintaining your own equipment, these handle the detailing work that makes the difference between a quick spray-down and actually getting components clean. The microfiber pulls contamination out rather than smearing it across adjacent surfaces the way rags tend to do.
