with or without a rider, a bicycle does need a well-balanced and maintained steering system to remain upright.
This comprises the handle bars, the handlebar stem, the front forks and the head-set.
the headset is an unglamorous but fundamental component of the bicycle. it’s also a part that takes terrific beating from the road. The ball bearings contained within the lower cup of a headset are loaded differently from those in all other rotating parts of the bicycle. They are loaded axially, and they hardly rotate – an undesirable situation as impacts from the road are transferred to stationary ball bearings. This is called ‘thrust stress’ and it can cause pitting or brinelling of the bearings. The problem is exacerbated riding off-road, or on a loaded touring bicycle.

Famed English street artist Banksy has created two pieces in response to the London Olympics. The two paintings appeared to have been crafted using his renowned stencil style, featuring athletes in a demonstration of their athletic power. One shows a man about to throw what appears to be a javelin, but is actually a missile. The second painting features a man performing a high jump, which is made to look like he’s jumping over a fence and onto an abandoned mattress. Interpretation on what they mean is open for discussion, but using a missile as a javelin seems to reflect the potential for danger at the London Olympics

In Uttar Pradesh, where the Samajwadi Party has just returned to power, the figure is higher, with more than 67% of households traveling by bicycle. That’s the highest percentage of all Indian states. Sikkim, in India’s northeast, had the lowest figure, with just 0.9% households owning bicycles.
