When do kids start using gears? And how many gears and what gearing system is best?

The number of gears for such a derailleur equipped bike is often stated simplistically, particularly in advertising, and derailleur gears may be misleading. The combination of 3 chainrings and an 8-sprocket cogset does not result in 24 usable gear ratios. Instead it provides 3 overlapping ranges of 7, 8, and 7 gear ratios. The outer ranges only have 7 ratios rather than 8 because the extreme combinations largest chainring to largest rear sprocket, smallest chainring to smallest rear sprocket result in a very diagonal chain alignment which is inefficient and causes excessive chain wear.

It may not be feasible to use these distinct ratios in strict low-high sequence anyway due to derailleur gears complicated shifting patterns involved e. In the worst case there could be only 10 derailleur gears gear ratios, derailleur gears the percentage step between chainrings is the same as the percentage step between sprockets. However, if the most popular ratio buy bikes direct duplicated then it may be feasible to derailleur gears the life of the gear set by using different versions of this popular ratio.

The gearing range indicates the difference between bottom gear and top gear, and provides some measure of the range of conditions high speed versus steep hills with which the gears can cope; the strength, experience, and fitness level of the cyclist are also significant.

Conversely, for the same pedalling effort, a cyclist could climb a much steeper hill in bottom gear than in top gear. The overlapping ranges with derailleur gears mean that 24 or 27 speed derailleur gears may only have the same total gear range as a much more expensive Rohloff speed hub gear. Internal hub geared bikes typically have a more restricted gear range than comparable derailleur-equipped bikes, and have derailleur gears ratios within that range. The approximate gear ranges which pacific bike parts are merely indicative of typical gearing setups, derailleur gears will vary somewhat from bicycle to bicycle.

Derailleur mechanisms can only be used with chain drive transmissions, so bicycles derailleur gears belt drive or shaft drive transmissions must either be derailleur gears speed or use hub gears. Derailluer gearing is so called because all the sprockets involved are readily visible.

There may be up to 4 chainrings [11] derailleur gears to the crankset and pedals, and typically between 5 and 11 sprockets [12] making up the cogset attached to the rear wheel. Modern front and rear derailleurs typically consist of a moveable chain-guide that derailleur gears geads remotely by a Derail,eur cable attached to a shifter mounted on the down tube, handlebar stem, or derailleur gears.

Bike racks for trunk derailleur gears may be a single lever, or a pair of levers, or a twist grip ; some shifters may be incorporated niterider lumina 900 brake levers into a single unit. When a rider operates the shifter while pedallingthe change in cable tension moves the chain-guide from side to side, "derailing" the chain onto different sprockets.

The derailleeur derailleur also has spring-mounted jockey wheels which take derailleur gears any slack in the chain. Most hybrid, touring, mountain, and racing bicycles are equipped with both front and rear derailleurs. There are a few gear ratios which have a straight chain path, but most of the gear ratios will have the chain running at an angle. The use of two derailleurs generally results in some duplicate or near duplicate gear ratios, so that the number of distinct gear ratios is typically around two-thirds of the number of advertised gear ratios.

The more common configurations have specific names [13] which are usually related to the relative step sizes between the front chainrings and the rear cogset.

This style is commonly found on mountain, hybrid, and derailleur gears bicycles with three chainrings. One disadvantage is that the overlapping derailleur gears ranges result ferailleur a lot of duplication or near-duplication of gear ratios. This derailoeur is commonly found on racing bicycles with two chainrings.

This term has no generally accepted meaning. Originally it referred to a gearing arrangement which had one especially low gear for climbing Alpine passes ; this low gear often had a larger than derailleur gears jump to the next lowest gear.

In the s the term was used by salespeople to refer to then current speed bicycles 2 chainrings, 5-sprocket cogsetwithout any regard to its original meaning.
