Product Information

What is it? A waterproof bag that attaches to your bicycle’s front frame and can hold your phone, keys, or other small items. The standard angle for the conical bore is 45 degrees. 36 degrees is now considered obsolete, but may occasionally be found on older frames. The tried-and-true loose-ball hub designs have lasted decades and make for easily serviceable systems.

The dimension of the headset is further defined by codes identifying the diameter of the fork steerer at the top and bottom of the head tube. This is the original threadless design. The bearings sit in external bearing cups, and the bearing cups are pressed into the top and bottom of the head tube. The split compression provides the interface between steerer and top bearing. Benedict Pfender / Immediate Media What is it? A versatile, weather-resistant steel basket designed to be mounted on the handlebars of your bicycle.They often have a corresponding universal identifier, which in the case of the aforementioned bearing, would be 6802, for instance. An integrated crown race (this one isn’t removable) interfaces directly with the headset bearings. Benedict Pfender / Immediate Media

Once the stem has been tightened, the top cap doesn’t serve any purpose. It’s just there to apply the initial preload before the stem secures the whole assembly. Loose ball bearings are sometimes held within a retainer, which is also known as a cage (hence the named ‘caged bearings’). This is usually made from pressed steel and holds the loose ball bearings apart from one another.Radial bearings are the most common as they are cheaper. They attempt to carry the load in a truly radial direction, which is vertical in terms of hubs, cranks, suspension pivots or derailleur pulleys. What is it? A high-tech helmet designed for adults. It comes equipped with a range of smart features, including an SOS alert system. What is it? A protective bicycle cover for outdoor storage of bicycles. It comes in different sizes to accommodate 1, 2, or 3 bikes. Instead of the steerer tube running vertically through the head tube, an angled headset makes use of the ‘spare space’ inside, to angle the steerer by up to 2 degrees. What is it? A t-shirt with a clever play on words, combining “cyclist” and “psychologist” to create the term “cycologist.”
