Is it possible to get fatter and lose weight at the same time? Thanks to a lightweight carbon profile, the FAT680’s save a pound of rotational weight compared to most alloy wheelsets, all while adding lateral stiffness.

The 80mm inner width runs a standard 4.3” tire up to a full size 5.0”, making it perfect for all-conditions of fatbike riding. It’s wide enough to tackle deep snow and sand, but still nimble enough on a tight single track.

Manufacturing process: Our air bladders are made from a special material which produces smoother walls, result in a lighter rim, and are completely removed without harsh chemicals. They are removed through the valve hole with a unique process so that the rim does not have to be patched like traditional manufacturers use. This significantly improves the strength of the rims. Read More about our process

T700: Constructed with premium Toray T700 carbon fiber. The best strength to weight ratio with no expense spared.

Tubeless: Tubeless (no tube) system performs perfectly at super low pressure. The rim mold is modified with better tubeless tyre setup , this design not only reinforces sidewall, also provides superior tire seal, especially for tubeless tires. Tubeless makes your fat bikes much lighter.

Double-wall: Double-wall construction makes fat bike rim with better stiffness and ride handling.

Ultra low profile: it makes fat rims light-weight and fast-rolling. The super-flat design provides better pinch flat protection.

Fast tire installtion: deeper tire bead channel provides easy tire mounting & dismounting for fat bike wheels.

Precise layup: Each rim carries its own layup schedule documents which are followed meticulously by the layup workers. Our Engineering team creates a unique fiber orientation which amplifies the desired riding characteristics for a given rim.

Bead lock: The small ridges on either side of the drop channel help secure tubeless tires in place. The bead lock makes it easier to seal up tubeless tires with a floor pump, and they are incredibly hard to burp.

For Non-Pro Series Rims: From the date of purchase, 3-year Standard Warranty.

For Pro Series Rims: From the date of purchase, 5-year Pro Warranty as standard and an upgraded optional lifetime Premium Warranty with minimum charge.

Crash Replacement: It is applicable with the same period as the warranty time range that you purchased for the rims with 10% /25% discount for Non-Pro series /Pro series.

Hi guys I ride a trek Farly with 26” x 82mm rims ( Jackalopes by trek). The rims are asymmetrical (have an off set) they take an 3.8 tire. My bike back end won’t take any bigger tire than that. What can you recommend as I have written off my front rim but I’m looking to replace both. Regards Brett Hand

LightBicycle 2019/01/30

Thank you for your inquiry! For trek Jackalope rim, it is 81.5mm outer/75.2mm inner. We recommend our FAT680 for you. It is okay for 3.8" tires. Don't worry about that. FAT680: 85mm outer/80mm inner, 20mm deep, 580g+/-20, USD196 each Do you like fat bike rims only or complete wheelset(built with hubs &spokes)? Thanks, Lightbicycle
