Nothing feels, performs, and lasts like a bespoke wheel. Every Bossi wheel is methodically hand built in store to exceptionally high standards, far above anything you would find off-the-shelf. Best in class components are selected to suit our customers needs and budget. Our wheels, true to our overarching philosophy, offer high performance without compromising durability - all backed by a 5 year warranty.
The Rims
Our carbon rims are manufactured from a blend of Torayca T700/800 and are produced from a single mould resulting in a light, stiff, and durable construction free from voids. The bladder is painstakingly removed through the spoke holes and not cut and patched like other brands. Designed and optimised specifically for disc brakes and wider tyres.
700cx30mm 28H
The 700c gravel rim is based on its road sibling but the higher spoke count (28) creates a stronger wheel capable of supporting larger loads. It features the same large 22mm internal width which comfortably mounts tyres up to 50c. The 700c rim is a hooked tubeless design meaning you can easily change between tubeless gravel tyres and road clinchers at a whim. This is the most versatile rim option for most gravel riders and can easily be swapped between gravel and road bikes; the one wheel to rule them all!
650Bx33mm 28H
Our 650B gravel rim is the choice for those wanting to max out tyre size on their gravel bikes. The smaller wheel diameter creates more clearance in the frame and fork which allows for larger tyres and lower pressure. In frames with limited clearance, 650B wheels and tyres may offer more grip than a 700c. The 650B rim sports a whopping 25mm internal width and is a hookless design compatible with most modern tubeless gravel tyres (check with supplier). Want to know if a 650B rim is the right option for you? Get in touch with our team and we'll help you make that decision.
