Incomprehensible to the laymen, the tubes protruding from the front wheel hubs are called BMX pegs. They are a necessity for performing tricks. The rider rests their foot on one or both of the pegs. Despite its apparent simplicity, this is an important part for fans of such bikes.
Standard peg sizes:
Thanks to special bolts, the attachment to the axle is rigid and strong. Pegs are put under tremendous strain when performing tricks. That's why they are made of high-quality steel alloys with the addition of titanium, chromium, and molybdenum. Lightweight pegs are made of strong alloys with aluminum plating inside.
Plastic lightweight pegs are the latest innovation from manufacturers. They are much cheaper and weigh no more than 120 grams. If used often, their service life is obviously shorter than that of steel.
