Product Information

Older loose bearings rolled directly on the hardened steel race. Benedict Pfender / Immediate Media The SHIS (Standardised Headset Identification System) describes headsets in a way that makes it easier to find what you need.

Instead, the head tube is bored with conical seats. When preload is applied, these angled seats result in the bearings self-aligning, as well as securing them in place, creating a rigid assembly. Birthdays – they’re a personal milestone, marking another year of adventures, learnings, and memories. For those who find solace on the saddle, breezing through trails or city streets, the right gifts for bike lovers can make their special day even more memorable. The stem – known as a quill stem – attaches separately, sliding inside the steerer tube. It is secured by tightening the top bolt, which engages an expanding wedge at its base to clamp the stem in place.

They may sound like a dry and boring topic (pun intended), but they have a big bearing (eyyy) on the overall performance of a bearing. Skaberne af denne LED cykellygte ønskede at få folk til at smile ude på vejene, og det er helt sikkert lykkedes for dem! Bike Balls er fremstillet af blød silikone og kan nemt fastgøres til din cykels sadelpind og giver et klart, iøjnefaldende lys. Desudener det den perfekte gaveidé, hvis du står og mangler en skør gave til næste arrangement. When it comes to gifts for a cyclist, it’s essential to remember that size isn’t always an indicator of value. Sometimes, the smallest tokens encapsulate the essence of their passion in the most beautiful ways. The conical shape of the race is centred on the fork steerer. This means it is self-centring on the bearing and, when preload is applied, the angled shape ensures it supports both axial and lateral loads. A top race performs the corresponding duties for the upper bearing.

Incidentally, the interface between bearing and fork is called the race (crown race and top race) because it originally acted as the raceway, with the bearing balls in the headset rolling directly on it.
