Glossary of Bicycling - G

G

gap

A distance between two or more riders large enough for drafting to no longer be effective. Also used as verb (US English), for example: "Contador has gapped Armstrong!". It's much easier for a stronger rider to pull ahead of others once a gap has been achieved; without a gap, the others can draft along using significantly less power to sustain the same speed as the rider in front. While gaps are usually achieved through attacks, on mountain climbs, where slower speeds means the advantage of drafting is much less significant, riders are often gapped who simply cannot maintain the tempo of the faster riders. A gap can also refer to the space in between a jump and the landing, which is common in mountain biking.

G.C.

Abbr.: general classification. the timing splits used to determine who is winning in a stage race. calculated from the first rider over the line each day time is then measured back by gaps from the winner of the day. Time gaps are then calculated back between riders and added to the overall position of riders relative to each other. Riders can attack in stage races for time rather than winning the days stage. They are said to be "riding for G.C.". In such circumstances alliances can form where some riders in a breakaway will work to help others win the days stage despite not contesting the finish as the overall gap the breakaway gains helps them "on G.C."

granny gear

Two meanings related to each other:

1. The lowest gear ratio on a multi-speed derailleur bicycle; smallest chainring in front and the largest at the back.
2. The smallest chainring on a crank with triple chainrings.

gruppetto

see autobus.

groupo

Also called a groupset; a complete (usually matching and certified compatible) set of bicycle drive control components. Generally includes the brake calipers, cranks, chainrings, bottom bracket, chain, front & rear derailleurs, cassette, brake and shift levers and the matching cables and housings; and may less commonly also include pedals and headset. The frame, forks, stem, seatpost, saddle, handlebars, hubs, rims, spokes, nipples and tyres are not considered part of a groupo even where manufacturers may market such components under the same product banner. The spelling "groupo" is an Anglicized version of the Italian gruppo.

gutter

To ride in the gutter is to ride close to edge of the road making it hard for others to draft.
