Chubby 275 Plus Specifications

27.5 plus, 29 minus…

call it what you want. We call it the CHUBBY 43.

The PHATTY’s slightly less plump little brother, the CHUBBY 43 offers the same HDP (High-Density Performance)  Foamcore technology and Solowall construction of its big bro coupled with an exceptionally strong 12K carbon weave in a 27.5+ rim. Designed to fit most 29er frames as well as dedicated 27.5+ frames, the CHUBBY provides a taste of the traction offered by fatbikes while maintaining the nimble and familiar ride of their all-mountain or trail bike, whether looking to make the most of the white stuff or just experience the trails in a new way.

chubby-maxxis-pkg-featureThe Chubby 27.5 Plus features a hefty 43-millimeter width (36-millimeter inner diameter) to maximize the footprint of your plus tires, effectively hitting the mute button on trail chatter and offering gobs of grip. We also engineered the scant 15-millimeter low-profile design to minimize damage from trail shrapnel to keep them looking better longer. The minimal surface area also means there’s no place for the nasty stuff to hang on, reducing unwanted weight and mess when shredding snow, sand and muck.

The CHUBBY tips the scales and just 480 grams, but it’s no lightweight when it comes to being punished on the trail. Light can be strong, and that’s why we crafted our Solowall rims from the strongest 12K carbon fiber available for a wheel that will shrug off impacts, then wrapped them around our aerospace-grade HDP Foamcore to enhance stiffness and damping qualities for a ride you’ll have to experience to believe. To top it off, the beefy 3.5-millimeter  hookless sidewall helps to dissipate the force of impacts when things get ugly.

Throw a set on your 29″ trail bike and experience the thrill of mountain biking all over again.

The Chubby 27.5 Plus 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 (illustrated above) while adding additional damping characteristics. The rim exterior is skinned with a custom blended impact-resistant layer of 12k weave carbon for additional protection and strength.

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.

Chubby 275 Plus Bead Ramp Details

Bead Lock

All Atomik Carbon rims utilize an angled bead lock to keep the tire bead positioned on the shelf when air is released from the tire and also adds a level of safety if a tire is leaking. 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.

Chubby 275 Plus Hook Thickness Details

Hookless Design

The hookless wall thickness is a whopping 3.5mm and designed to help displace impact. The wall thickness is much greater than traditional hookless 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.

Chubby 275 Plus Impact Resistance Details

Impact Resistant Construction

The Chubby 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 (illustrated above).
