The Origin8 rim has a 42mm profile and is perhaps the most popular in the fixie community, with stainless-steel spokes, sealed bearing hubs and double aluminium walls. This CNC rim has a machined braking wall, making it perfect for mounting brakes. It is a wider edged than the Weinmann rims with more aluminium to show off the colours. This makes is a little more aggressive and flashy. We propose radial spoking for aesthetic reasons, but these are weaker than cross spoking. If you prefer this wheel with cross spoking, which is stronger, just make a note in the final step of the purchase process. Origin8 rims stand out as excellent quality for money, making them the queens of fixed-gear bikes. The size is 700c, meaning it is compatible with all road-bike tyres. You can mount 23, 25 or 28 tyres and will need a 60mm-valve inner tube. And it is crucial you mount a rim strip between the tyre and the inner tube to reduce or prevent punctures.
