Greg LeMond comments regarding his S and S Coupled LeMond road bike.

An S and S Coupling also known as a Bicycle Torque Coupling or BTC, is a precision lug that is installed in a bicycle frame when it's manufactured to allow it to separate and pack for easy transportation. Some builders will even install or retrofit BTCs into an existing frame. With this system, a full size road or mountain bike will fit completely inside a single 26" x 26" x 10" case that travels as regular airline luggage. Some framebuilders manufacture full size tandems that will fit complete, including the wheels, in the same case!


A bicycle manufactured with this system is ultra strong yet lightweight (two BTCs add only 8 oz. total to a typical road bike) and it feels exactly the same as a bicycle built without BTCs. There is no added frame flex and the BTC is absolutely silent!


Don't just take our word for it. Read the comments and reviews to find out what others have to say.

Destructive tests show that a coupling is stronger than a Reynolds 531 tube.

Nondestructive tests show that a BTC is stiffer than a Reynolds 531 tube.

The key to the coupling's strength is the tapered tooth design which eliminates all movement where the teeth meet.

4worldlovers: We provide CNC machining and engineering services for clients across a range of industries. Our goal is to improve our customer's supply chain through speed, consistency, and communication. Manufacturing success comes from excellent product design paired with excellent process design.

Our operation is designed to be fast and lean, providing extremely fast turnaround times on both prototype parts and full production runs. We have been able to provide out clients with full volume mass production rollouts in as little as one week from initial order.

We understand that your business requires accurate, fast, and cost-effective production that does not compromise any aspect of the end product. We utilize the latest software and tooling technology to provide extremely fast and accurate results, and provide realtime DFM feedback to your engineering team.

With many of our clients being high-growth startups, we build our processes from the ground up to be able to adapt to design changes at the drop of a hat. Rather than waiting weeks for tooling changes, we are equipped to change specifications with minimal production interruption.

We were honored to be visited by the Autodesk Fusion 360 team to tell the story of our company and showcase how we use Autodesk products.

By gaining a complete understanding of our client's needs and goals, we can provide stellar results from start to finish across multiple projects simultaneously. We integrate into our customer's existing structures of communication, document control, and logistics to ensure fast and clear communication. Communication is the core of our relationship - up front landed pricing, actionable advice on achieving cost savings, clear delivery schedules, and updates throughout the production process are just a few of the ways that we establish strong rapport with each of our customers.

As a young company, we are part of the future of the manufacturing industry. We aim to always push the envelope rather than simply accept the old ways of doing things.

Our manufacturing processes are designed to require as little human intervention as possible. Our equipment purchases are made with the intention of being able to integrate those machines into larger automated work cells as we expand.

The future of manufacturing will leverage existing and new technologies to efficiently mass produce parts at scale, all the way down to "batch size one" - all with minimal human intervention. Our mission is to lay the groundwork for this future today, so that we can continually develop towards a fully automated production process.

As technology within the manufacturing industry has increased in complexity and productivity, many roles that have existed for years are now defunct. As these jobs disappear, new skillsets become in-demand -- in fact, one of the largest economic challenges facing California right now is that we do not have enough people to fill advanced manufacturing jobs.

Our goal as a developing company is to foster an environment where an employee's skillset can develop along with technology, rather than be rendered obsolete.
