Bicycle frames are constructed from materials which place emphasis on being strong, lightweight and stiff to aid power transfer. Aluminium, titanium, steel and carbon are widely used in all levels of frame production.
Brake and gear cables are traditionally attached to bicycle frames with lugs on the outside of the tubing, this is known as external routing.
Recent advances in technology have allowed manufacturers to route the cables through the inside of the tubing, this is known as internal routing. Internal routing gives a very clean appearance, can increase the stiffness of the frame due to additional channels and in some cases may provide aerodynamic benefits too.
For certain applications, including full suspension bikes and cyclocross bikes, manufacturers use an outer cable along the full length of the cable to protect the inners from mud, water or accidental damage, this is known as full outer.
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 fuelled by advancing technology, industry trends and customer demand for a particular feature or style of bicycle.
BMX stunt bikes are impressively agile and their high handlebar position and 20 inch wheels make them ideal for performing tricks and stunts. BMX stands for Bicycle Moto-X and its origins lie in race circuits with banked corners, jumps and rhythm sections. BMX race bikes are lightweight and stiff to aid power transfer and withstand the jumps of a race circuit.
BMX riding spans across a number of disciplines such as street, skate-park, dirt jumping and BMX racing. It’s essential that you identify which discipline is for you and purchase a BMX bike that has the right characteristics for your kind of riding. Please consult Wiggle’s bike buying guide to learn more about the various types of bicycle and how to identify the right bike for YOU.
