AJ has demonstrated over 20 years of leadership through successful military and business management.  Prior to co-founding Sphere Brakes, LLC, Aaron served 12 years in the US Army as a decorated military officer while leading several business operations at GE Transportation in Erie, PA.  He is named inventor on 13 sphere brake issued and pending patents.  AJ holds a Master’s Degree from Penn State University.

Jason Pintea, Lean Leader

Jason was hired at thee start of 2019 to take on the challenge of setting up SBD’s new supply chain and establish the Lean Enterprise System.  He has worked in large and small companies from quality, production, operations, and lean management.  Jason is responsible for maturing the production readiness levels of wheel-end technology across the product lines.  He is named co-inventor on the new patent pending Frictionless Regenerative Eddy Sphere Brake.

Joe Fiore, Director of R&D

Joe was hired in 2019 after working on a joint project with Sphere Brakes for the two cycle industry.  He holds over 75 patents in multiple industries from auto to juvenile product lines.  Joe is responsible for rolling out the innovation strategy, engineering, and test coordination across all product lines.  He is named co-inventor of on the Frictionless Regenerative Eddy Sphere Brake and the Hydraulic Sphere Brake.

Build – Measure – Learn

We are unlike our competitors because we leverage the power of the Build – Measure – Learn feedback loop to deliver new dual-use wheel-end technology at a fraction of the cost while operating with flexibility as a lean start up across multiple industries. The strengths of the company are its people, practices, and unwavering customer service.

We are with our customers every step of the way.  Whether we visit local maintenance shops, regional fleet owners, or conduct MVP review days showcasing and assessing products in development – our hands-on approach ensures that an engagement will not end until our customers and partners are completely satisfied with the deliverables.

Sphere Brakes perform. I'm very excited about Sphere brakes for a few reasons. It performs as-good and better than a disc brake with less up-front and maintenance costs. It's much safer for our technicians to replace the brake pad because you do not have to remove the wheel. For these reasons, we're excited to integrate Sphere Brakes into our fleet.- Harold H. Bender - President, Team Hardinger


Disc and drum brakes were invented at the turn of the 20th century, back when electricity was in it’s infancy; approximately 120 years ago. In 2010, AJ invented the first sphere brake while serving in Kuwait, heading into Iraq. The sphere brake unlocks new value to any industry leveraging more surface area in a smaller diameter. These systems directly compete in size, weight and performance. We are focused on optimizing this sphere brake technology by aligning with strategic partners in multiple industries.
A/H Sphere Brakes

Sphere brakes are the only brakes in the world you can change brake pads without any tools, just your bare hands!  In service brake applications, the patented sphere brake technology compresses hemispherical pads on an outer spherical surface.  This inherent design allows multi-directional brake force application around the brake surface generating more torque with a smaller brake effective diameter.  In driveline applications, the sphere brake mounts in-line with the drive shaft between the transmission and drive axels; It’s actuated by an electrical, mechanical, pneumatic, or hydraulic system controlled by the driver.  Like the service brake, hemispherical pads compress around the sphere brake surface typically in an enclosed housing.

Hydraulic sphere brakes for e-mobility

In partnership with Cleveland CycleWerks, we launched the worlds’ first Hydraulic Sphere Brake (HSB).  Advantages of developments in HSB application include the fact that it’s the first brake system which does not require tools to change brake pads.  Due to inherent design, the brake itself produces more torque in a much smaller package.  The HSB is lighter than the required disk brake for the same platform.  It is positioned more towards the center line fo the motorcycle, increasing stability and performance; and the brake is affordable in high growth industries like e-mobility.  The HSB has been installed on a Cleveland CycleWerks ACE motorcycle for road testing and certification.  The new HSB will be offered on a Falcon 2021 production models.
