    TECHNOLOGY

    HANDMADE IN THE USA

    Alto engineers with purpose and creates products that are designed to improve upon and eliminate existing industry ailments -- specifically addressing lateral stiffness, ride quality, and durability. All Alto wheels have unlimited rider weight restrictions and a 5 year warranty!

    R-SYMMETRIC DESIGN

    A balanced wheel is a stiff wheel, and therefore a faster wheel. Alto set out to determine the answer to a specific engineering optimization question: what is the perfect hub geometry and spoke lacing pattern that will create the most balanced, most durable, and stiffest wheel possible? It took many months of programming, but the results were well worth it.

    CARBON RIMS

    Alto carbon rims are created using a unidirectional filament winding process that results in the stiffest and most durable laminate structure in the world. It is their laminate design, along with their new high temperature resin, that make Alto rims the most technologically advanced on the market.

    BRAKE TRACK TESTING

    ONE-PIECE ADJUSTABLE AXLES

    Premature bearing wear is way too common, and Alto designed a one-piece axle that will put a stop to the madness. The one-piece design, along with the use of aluminum 7075, means that the axle will not bend and flex under load. So the bearings won't torque and become damaged every time you stand and put the power down. The plug and collar system removes all thrust loading from Alto's NSK and CeramicSpeed bearings, allowing them to spin free for thousands of miles. It's a simple and efficient design that results in durability and speed.

    LABYRINTH SEALED HUBS AND NSK ABEC7 BEARINGS

    Have you ever spun a wheel in your hands and had it feel, well, not so good? We all hate that. Alto created a system that would allow for free spinning bearings and ultra fast wheels. A labyrinth seal is machined directly into Alto's hubs, with extremely tight tolerances and material overlaps that make it impossible for water and debris to reach those precious bearings. There are no plastic dust shields to create drag, and no energy lost to unnecessary friction.

    TESTING

    Alto leaves nothing to chance. Their engineers are using state of the art solid modeling and finite element analysis to optimize every design. They test each part in every load condition to be sure it is as light as possible while also staying well above the required factor of safety. Optimization at its finest.
