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! What is a BTC in German How will the bicycle ride? 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. Crash tests (riders came out fine): Test 1, bicycle hit by a Harley Davidson Test 2, bicycle hit by an ice cream truck Test 3, Colnago tangles with a Saturn The key to the coupling's strength is the tapered tooth design which eliminates all movement where the teeth meet. When the nut is tightened with a spanner wrench, the teeth wedge together and lock to produce a rigid, zero clearance joint that remains tight. All components are precision CNC machined for a perfect fit.

WizWheelz tandem recumbent in 2 sections Custom Carved BTCs S&S Coupled Bike Postage Stamp Why buy a bike with BTCs™? Benefits Features Can I buy a complete bike manufactured with BTCs™? Yes. Almost all the listed framebuilders offer complete bikes in either standard or custom configurations. Some framebuilders stock complete travel bike systems including the case and accessories. What type bikes are available? Road, mountain, hybrid, touring, cyclocross, tandem, track and recumbent (triangulated frames only, not monotube) bicycles and tricycles are all available. BTCs™ are as much at home in a USCF Nationals road race as they are down hill mountain bike racing or touring around the world. Standard model This is the fastest and most economical way to purchase a new frame or complete bicycle. The design, available sizes and features are usually standardized. Some framebuilders keep these models in stock for faster delivery. Custom design This category offers a wide range of design flexibility. It includes anything from minor changes in a standard model to a specialized design that fits you perfectly. It's now possible to get a travel bike in almost any style you want and with almost any feature you can imagine. Retrofit an existing bike Many of the builders that manufacture new bikes offer retrofitting services. If you aren't in the market for a new bike it may be possible to install BTCs&trade; in your steel or titanium frame. Contact a framebuilder that does retrofits to see if it makes sense for you. Most framebuilders will do retrofits but some my try to discourage it with high prices. Shopping for a builder that specializes in retrofitting can make a huge difference in the price! Not for use on monotube frames. Triangulated frames, such as conventional single and tandem bicycles and recumbent single and tandem bicycles, are ideally suited for S and S Couplings. Monotube frames are not compatible with S and S Couplings. That restriction is based on our concern for safety. A monotube frame coupling sees primarily bending compared to a triangulated frame coupling that sees primarily tension and compression. Since our product wasn't designed or tested for that type of loading, we don't sell it for that purpose. We do allow it's use on monotube frames that have a structural seat frame that connects the two frame halves in addition to the couplings . With that said, we have had companies test our couplings on a limited basis on monotube frames and they have held up fine. It is possible, that with additional testing, we may someday approve of their use on some specific monotube frames. It is unlikely that we will ever approve the use of couplings for retrofitting monotube frames. Should I buy a new frame or retrofit my existing frame? BTCs™ can be installed on new frames or retrofit into existing steel, titanium or carbon fiber frames. (aluminum frames can't be retrofit). For framebuilders, it's simpler to build a new frame because they install the coupling in a tube in advance, then they miter the tube assembly to fit the frame. The assembled tube is then treated like a solid tube so the actual frame building procedure is unchanged. Painting isn't a factor on a new frame since paint is part of the manufacturing process with or without couplings. With retrofits, the builder cuts the top and down tubes and removes a short section of tube then replaces the removed section with a coupling. Before a builder can install couplings, they first determine what type tubes were used when the frame was built. In some cases, due to the shortness of tube butting etc., a tube or two may not be suitable to accept a coupling and will need to be replaced. Tube replacement can be expensive, therefore, retrofitting may sometimes be impractical. In addition to installing the couplings, repainting or touch-up will be necessary since about an inch or two of paint will be burned when brazing in the couplings. The ideal time to retrofit is when frame repair or paint is needed anyway. In most cases, couplings can only be retrofit to round tubes. Some builders can change the profile of an odd shaped tube to make it accommodate a round coupling so check with your framebuilder before ruling out the possibility of fitting odd shaped tubes with S and S Couplings. To determine if you bike is suitable for retrofitting, check with the builders listed on the framebuilder list. To pick a builder to do a retrofit for you, first review the framebuilder list under retrofitting for a builder that does the type of bike that you have. Looking through our photo gallery of retrofitted single and tandem bicycles and the owner testimony pages my also help you pick a builder. S and S Machine does not evaluate bikes to determine their suitability for retrofitting, Check with some framebuilders to determine if you bike is a good candidate or not. Not all framebuilders will do retrofitting. S and S Machine does not do retrofits, only framebuilders do retrofitting. How are they installed? Steel frames: Stainless steel BTCs™ are used on steel or alloy steel frame tubes such as chrome-moly. Columbus, Dedacciai, Reynolds, Tange and True Temper are only a few of the manufacturers that make steel tubes that can be fit with stainless steel BTCs™. The lug halves of the coupling slip over the outside of the frame tube and are silver brazed in place. These couplings are ideal for both new bikes and retrofitting since they fit the outside diameter of the tube which remains constant regardless of the wall thickness. Or Chrome-moly BTCs™. These couplings use plated chrome-moly lugs and our standard 17-4 stainless steel nut. The lugs press fit into the inside of the frame tube and are TIG welded in place. Rubber sleeves cover the weld and paint line eliminating costly masking which makes installation faster and less expensive. The rubber sleeves also provide a dust seal at both ends of the nut. These couplings were designed for production use only and are not intended to be retrofit into existing steel frames. Retrofitting limitations are primarily due to the difficulty involved in press fitting the coupling into an existing frame tube. Chrome-moly couplings are also produced to fit only a limited number of specific wall thickness tubes (tube outside diameter stays the same and the inside diameter changes as wall thickness varies). It is unlikely that we will manufacture all the sizes required to fit the various inside diameters encountered when retrofitting. Stainless steel frames: The same as steel frames done using stainless steel BTCs™ Titanium frames: Titanium BTCs™ are used on titanium frames (uses our standard 17-4 stainless steel nut). The titanium lugs press fit into the inside of the frame tube and are TIG welded in place. Titanium beauty rings cover the weld. The "machine to fit" couplings are designed to be machined by the framebuilder to fit tube wall thicknesses that are a size other than the sizes we stock and are commonly used for retrofitting. Aluminum frames Aluminum frames can't be retrofit. Carbon fiber frames: Modified titanium couplings and special aluminum couplings designed for CF are being used on carbon fiber frames manufactured or retrofit by Calfee Design. Where can I buy them? Consumers should purchase complete bikes, frames manufactured with BTCs™ and accessory items from a local retailer. If your retailer doesn't carry bicycles with BTCs™ and is unable to work with a listed framebuilder, we suggest you contact a framebuilder to locate a retailer in your area. In areas where a framebuilder isn't represented, they may sell to you direct, but there is usually no price advantage. Some framebuilders don't sell through retailers, they only sell direct to consumers. For information regarding whether a framebuilder sells direct or through retailers, see the builder profile for each framebuilder which can be found by clicking on the framebuilder's name on the framebuilder lists.. Retrofitting BTCs™ to your existing frame can be arranged through a retailer but it is more commonly done by going direct to a framebuilder. BTCs™ are sold only to professional bicycle framebuilders.

BTCs™ are precision CNC machined from solid bar on a Mazak 625 Multiplex. This machine tool has twin turning spindles plus milling for improved accuracy over conventional CNCs. Precision machining parts isn't new to us. We have been making precision machined parts since 1976 so holding close tolerances is routine for us. Coupling specifications including size, weight, material and photo Stainless steel "classic" BTCs (used on most new steel frames and retrofits) Stainless steel "BTC2" Couplings (internal lugs for a minimalist look) Titanium BTCs (used only on new titanium or carbon fiber frames and retrofits, won't work on steel frames) Titanium with hidden welds "original style" Titanium with visible welds Chrome-moly TIG weldable BTCs. (limited use on new steel frames, rarely on retrofits) Why was the first BTC™ built? It all began when I wanted to take my bike on a Mediterranean cruise.
