Sheldon Brown-Bicycle Technical Information. Lubricate your bike. Learn to Love to Lubricate and who doesn't? An informative guide for a simple, yet mission critical set of maintenance tasks for your two-wheeled human-powered conveyance. Compared to an automobile or a SH-60B/F Seahawk helicopter, your bicycle has relatively few moving parts, and is pretty simple to maintain. But, like almost every mechanical system with moving parts, lubrication is critical. Not only will keeping your bike lubed extend the chain life and help keep your shifting and braking systems in tune, but it also helps get more power from your ass to the rubber to the road.

And that folks is the name of the game. It's simple. So, without further preamble, delay, or dissimulation, here's how to grease up the old velocipede.

Fabric Cloth fabric is woven between the two beads to form the body or "carcass" of the tire. The fabric threads don't interweave with crossing threads as with normal cloth, but are arranged in layers or "plies" of parallel threads. Some tires use thick thread, some use thin thread for the fabric. The higher the TPI number, the thinner and more flexible the tire fabric is. Bicycle tires have the threads of the fabric running diagonally, ("bias") from bead to bead. Rubber Tubular Tires Bars. Bikely.
