An Italian manufacturer of cycle components. Their road components increase in quality and price from veloce, centaur, athena, chorus, record and super record.
Carbon frame
Carbon fibre is the material of choice for top level bikes. It is strong, stiff and light. In addition the carbon is considered to absorb vibrations from the road and produce a comfortable ride.
Cassette
A cluster of sprockets that fits on the freewheel at the rear of the bike that (along with the front chainring) has the gearing effect on the bike. The effort the rider needs to make to turn the crank (all things being equal) is greater when the chain is on the smallest sprocket in the cassette.
Chain
Links the chainring to the cassette.
Chainring
A front sprocket that attaches to the crank. The effort the rider needs to make to turn the crank (all things being equal) is greater when the chain is on the large chainring.
Classified Climbs
Climbs in professional racing are classified depending on how difficult they are. The easiest classified climb is a class 4. The hardest is referred to as HC or hors categorie (ie beyond categorisation). A typical HC climb will be around 20km long and have an average gradient of greater than 6%.
Clipless Pedals
Clipless pedals permit cleated cycling shoes to clip in and out of the pedals.
Col
A mountain top pass. (French)
Crank
The arm that attaches to the axle via the bottom bracket. The pedals are attached to the end of the crank.
Cruiser
Type of bike popular in US beach states, such as Florida and Southern California. They have fat tires, no gears and a low riding position which makes them fine to ride on the flat but would not survive long in the hills. Very popular in the 40s and 50s and now making something of a comeback. Also know as a Lowrider
