It's called 'obsolete' If you're restoring a period bike, it is ,as you said, 'stainless gear casing'. We have it, as will LBS which commonly service classic bicycles. If you have a modern bike it would be called 'the problem' because its slop would be deleterious to a crisp shift response. Modern gear casing is different, a high-helix casing of tempered wire with a PTFE liner. Any LBS has that. Regarding length, as with all casing, shoot for a clean economical curve. Avoid short runs which kink at the ends and long cuts resulting in recurves. Take care to trim evenly and use the appropriate ferrules which both keep the casing from self-disassembling and prevent lost motion. Even small amounts of 'slop' in a gear control is noticeable. Oil wires in modern casing and grease wires in older unlined stuff. -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971 |
