Frame Material

Bicycle frames are constructed from materials which place emphasis on being strong, lightweight and stiff to aid power transfer. Aluminum, titanium, steel and carbon are widely used in all levels of frame production.

Fork Materials

Cycling forks are made from a wide range of materials such as aluminum, steel, carbon and titanium. Each material has its own unique set of qualities that can greatly impact ride performance.

Model Year

Major bike manufacturers produce a new range of bikes on an annual basis and this determines the model year of a particular bike. This annual turnover is fueled by advancing technology, industry trends and customer demand for a particular feature or style of bicycle.

Wheel Size

Bicycle wheels come in a wide range of sizes from 12" wheels found on smaller Kids Bikes to larger 29" Mountain Bike and 700c Road Bike wheels. Larger wheels are normally faster and more stable at speed and their larger contact patch improves grip too. Smaller wheels are normally lighter, more maneuverable and have quicker acceleration.

Wheel sizes are defined by the country that first popularized the style of bike that used them - so you'll see some imperial and some metric measurements listed. Wiggle includes the ISO standard in brackets after each for ease of comparison.
