Other technical bicycle setup specifics can include zero offset forks, narrow handlebars, very high pressure tires (100psi and higher), and a very small front sprocket (18-28 teeth).

A small sprocket in the drive system turns the chain or belt at the transmission end, which then turns a larger sprocket at the tire end, making the tire move.

Some cassette systems from the late 1980s and early 1990s use a threaded small sprocket to hold on the larger splined sprockets, the entire set referred to as a cluster.

To allow for the smaller sprockets to slide into the hub, the larger gears were away from the wheel (unlike modern sprockets).

Compact gearing is not necessarily lower than standard gearing if cassettes with smaller sprockets (such as 11-23) are used.

Efficiency generally decreases with smaller sprocket and chainring sizes.

High normal or top normal rear derailleurs return the chain to the smallest sprocket on the cassette when no cable tension is applied.

In this condition, spring pressure takes care of the easier change to smaller sprockets.

However, the Capreo groupset is specifically designed for small-wheel bicycles as its smallest 9-tooth sprocket compensates for the small wheel size.

At the rear I had a nine-speed cassette, but removed the second smallest sprocket to allow room for the chain to clear the tyre in the highest gear.
