Phatty 85mm

Thin is the new fat.
Meet the PHATTY 85.

Light, strong, sleek, and ready to to tackle all terrain goodness.

Created for the type of rider willing to take two wheels into conditions that would leave lesser mountain bikers safely indoors, the all-new Atomik Carbon PHATTY 85 is here. The single greatest upgrade available for any fatbike, the PHATTY 85 features a monster 85-millimeter width (77-millimeter inner diameter) to maximize the footprint of your fat tires and give you a ride with ungodly grip in all conditions.

Featuring HDP (High-Density Performance) Foamcore technology and Solowall construction, this aerospace-inspired carbon fat rim sets the standard for strength, weight and ride quality with an impressive 16-millimeter low-profile design engineered to minimize damage from trail shrapnel to keep them looking better longer. The minimal surface area also means the nasty stuff you’re likely to encounter in loose conditions where big tires shine—from snow, to muck, to sand—won’t have much to cling to, reducing unwanted weight and mess.

Although the PHATTY 85 is deceivingly light at 590 grams, don’t be fooled—it’s still a heavyweight built to take abuse. Light can be strong, and that’s why we wrapped our high-modulus blend of Toray 700 and 800 around our aerospace-grade HDP Foamcore to enhance stiffness and damping qualities for a ride you’ll have to experience to believe.

A beefy 3.5-millimeter modified bead hook helps to dissipate the force of impacts through the sidewall when things get ugly, and BeadLock allows you to run lower pressures for maximum traction.

Throw a set on your fat bike and see how the Phatty can transform you ride.

Rims: $625 each
Complete wheel set starting at: $1,825

The Phatty features an aerospace foam core wrapped in a layer of composite material that is molded into the structure, creating a pseudo-semi wall rim that boasts increased impact strength, energy dissipation and stiffness, while adding additional damping characteristics.

An added benefit of the extreme low profile of the rim is a greatly reduced surface area. This ultra low profile reduces the amount of rim surface that is exposed to sidewall impacts and trail debris, therefor limiting the exposure of the rim to damage.

Bead Lock

Todas los rines Atomik Carbón  utilizan un seguro en angulo para el talón del neumático para mantenerlo posicionado cuando se sale el aire de la llanta y también da un nivel de seguridad si la llanta tiene algún hueco. Esto le permite refrescar el sellante sin que el neumático caiga al centro del rin, lo cual resulta en más dificultad para re-inflar. This features allows you to refresh sealant without having the tire bead fall into the center of the rim, resulting in a tire that is more difficult to inflate and re-seat.

Hooked Design

The hooked wall thickness is a whopping 3.5mm and designed to help displace impact. The wall thickness is much greater than traditional designs (as shown in the illustration above) and the additional strength provided by the thicker sidewall yields a rim that is light and extremely strong.
