Many of the 8mm diameter pinch bolts (item P3c above) sold on the internet will slip if the bolt is not tightened with a pliers holding onto the round 8mm barrel. This is because the 5mm bolt does not have a dome shaped end. Myrons cuts a rounded dome in the 5mm pinch bolt. This makes it gently fold the wire into a curve when the bolt is tightened.
You pay more for a Myrons pinch bolt, but you will get a much greater benefit. Safety (it won’t pop off when you slam on the brakes), and ease of installation (don’t normally need a pliers to hold the round barrel). You can feel the cable bending as the bolt is tightened. That gentle bending is what makes it not slip. See pictures at left.
The 5.5mm diameter pinch bolts (item P1 above) for throttles already have domes on their 3mm bolts. (cones actually). So they are designed to hold good, yet be small. Nonetheless, they often need to be soldered, in addition to the pinch bolt tightened as much as possible, in order to not slip.

These bicycle cable ends are listed here to show how much different they are from motorcycle cable ends. A bicycle gear cable 4mm end could be ground down to become a motorcycle throttle cable 3mm end. A bicycle brake cable road type interchanges with a motorcycle pear or mushroom type. A bicycle brake MTB type 7mm end fits loosely into a 8 or 9mm motorcycle brake lever, but functions OK.

The above step ferrules all fit loosely over the cable conduit. The end cap type ferrules below fit tight on the conduit, or are crimped on by special pliers. The end caps are supposed to fit tight, for several reasons: For strength and cable performance, to help keep out dirt and water (thus increasing lifetime), and for easier servicing. Unlike the step ferrules, which are necessary, the end cap ferrules are not necessary. Sometimes conduits need to be cut and the end cap ferrule needs to be left off. The conduit will still function good without end caps, as long as the adjuster or other stop piece hole, usually 2.5mm, is not too big. Without a 6mm OD end cap ferrule, a 5mm conduit will eventually slip through an improper stop piece hole, like 4mm instead of 2.5mm. But as long as the holes in the end pieces are the proper size, the cable does not need end cap ferrules.

5. B: Bulk wire, conduit, and sleeve
Sometimes very long cables are needed, for long bikes, or very tall handlebars, or for other things that use mechanical control cables. For 1.2mm and 1.6mm thick inner wires, up to 8 feet, it is better to use bicycle wires. beacuse they already have end(s) and cost less. The same quality 5mm conduit (housing) for bicycles costs much less than for motorcycles, and comes in colors. For thicker or longer cables, the bulk motorcycle wire and black conduit is the only choice.Cable inner wire from Motorcycle Parts Suppliers (Flanders): B1 610-03080 cable wire by the foot 1.2mm 1 x 9 strand $0.80/ft stiff braid (throttle) cable wire 8.5 feet 1.2mm 1 x 9 strand stainless use W10 B2 610-03090 cable wire by the foot 1.2mm 7 x 7 strand N/A soft braid (throttle) B3 610-03100 cable wire by the foot 1.6mm 1 x 9 strand N/A stiff braid (brake) B4 610-03110 cable wire by the foot 1.6mm 7 x 7 strand $1.00/ft soft braid (brake) cable wire 9.0 feet 1.5mm 1 x 9 strand stainless use W11 B6 610-03120 cable wire by the foot 2.1mm 1 x 9 strand $1.30/ft stiff braid (brake) Conduit (housing) from Motorcycle Parts Suppliers (Flanders): B7 610-03300 cable conduit per foot 5.0 x 2.3 black for 1.2 or 1.6 wire N/A use B13 B8 610-03305 cable conduit per foot 4.8 x 2.1 black, nylon-lined, for 1.2 wire N/A use B13 B9 610-03310 cable conduit per foot 5.5 x 2.9 black for 2.0 wire N/A B10 610-03315 cable conduit per foot 5.5 x 2.5 black, nylon-lined, for 1.6 wire N/A

6. Cloth Cable Restoration
Since World War II, most cable conduit is coated with soft nylon or vinyl type plastic, to be flexible and waterproof. But before the 1950’s, most cable was coated in woven cotton cloth. The same is true with electrical wires. Early 1900’s electrical wires had cloth insulation, while late 1900’s wires had soft plastic.
Modern plastic coated cables will replace the older woven types, but they do not have the old fashioned appearance. None of the normal cable suppliers, bicycle or motorcycle, sell cloth coated cables.
One historic old bicycle with cloth covered cables was the 1939-1945 BSA Airborne Bicycle. In WWII British commandos would jump out of planes with these bicycles and then quietly ride miles undetected to the destination.
In 2014 a bike mechanic in Canada was restoring a BSA Airborne Bicycle. He ordered cable parts from Myrons Mopeds. That inspired Shaun to find a way to make cloth cables. A few days later, walking down the sidewalk, Shaun saw a purple Lakers shoelace laying on the sidewalk. It was big enough to see that it was actually a hollow tube. At that moment Shaun realized that most shoelaces are hollow tubes, in different sizes, colors, and lengths. A hollow cloth tube made from a shoelace could cover a modern cable to make it look “vintage”.
In 2015 an medical engineer in Alabama was restoring a different BSA Airborne Bicycle. He ordered cable parts from Myrons Mopeds. Shaun mentioned the idea of using shoelaces to reproduce vintage cloth cables. A few months later that person made this detailed report on how he successfully made accurate replica cloth cables out of modern plastic ones.
