Bicycle rollers

Rollers are also used by bicycle racers to finely tune their balance, a skill needed for drafting and the close quarters of a peloton during races.

[citation needed] Novice cyclists often start by placing the bicycle rollers in a hallway or door frame where there is a nearby wall for support in the case of a fall.

Removing any sharp and dangerous objects from the area is a must and a helmet is often worn, even though the user might be indoors.

Beginners quickly discover that it is easier to maintain one's balance by focusing on a point a few yards ahead rather than looking directly down at the front wheel.

Also, the user has no forward momentum while on bicycle rollers, which drastically reduces the possibility of injury in the event of a loss of balance or a fall.

[4] Aluminum alloy is usually a better choice because plastic rollers tend to bend and become misshapen from their regular cylindrical shape after use.

A bicycle on the road can move fore and aft relative to the rider, and these rollers attempt to duplicate this effect.

Timing systems either use modern electronics and digital projection, or a large analog clock with a hand for every rider representing their distance traveled.
