Wartung englischer Drei-Gang-Fahrräder: Unterschied zwischen den Versionen

Read that page! Most old three-speed bikes have the gear range set unreasonably high -- and that page will tell you, among other things, how to correct that problem.

oldeng24ost English 3-speeds use brake calipers that are adjusted differently than conventional sidepulls. They usually have a slot for a flat-head screwdriver on the end of the center-bolt. This is used differently depending on the brand.

Old-style brakeoldeng24lder Raleigh brakes are identified by the special cables they require. These cables do not use anchor bolts. Instead, they have soldered lugs at both ends. Replacement cables came with the adjusting barrels. To replace them, you would remove the nut that held the old adjusting barrel fitting to the caliper, and switch over the whole assembly. When available, the cables came in three varieties: "front", "gent's rear" and "lady's rear". The "lady's rear" was longer and had the adjusting barrel facing the other way. Good luck finding replacements today.

The center bolts on "Raleigh-type" brakes are not adjustable. The spring block has a shoulder that is made to be just the right length so that the caliper arms can move freely. The spring block has a plain, un-threaded hole, so tightening it with the screwdriver end is the same as tightening the nut that holds the caliper to the bike.

oldeng24hillips-type" brakes use a conventional cable anchor bolt and a regular single-ended cable. Unlike the "Raleigh-type" calipers, the center bolt is adjustable. Much like Shimano side-pulls, turning the center bolt (with a screwdriver) adjusts the free play of the caliper arms. Unlike Shimano side-pulls, there is no separate locknut, so the same nut that holds the caliper to the bike acts as a locknut.

Both "Raleigh-type" and "Phillips-type" brakes usually have a fiber washer between the two caliper arms on the center bolt. This should get a drop of oil from time to time.

==Tires ("Tyres")==

oldeng24t is also important to remember that although 3-speeds usually take "26 inch" tires and tubes, they are not interchangeable with mountain-bike size 26 inch rubber. The vast majority use the English 26 X 1 3/8 size. This has a different bead-seat diameter (I.S.O.590 mm), and will only take tires marked 26 X 1 3/8. This size is also sometimes designated "E.A.3". Occasionally, you may run into a "high performance" English 3-speed that takes 26 X 1 1/4 (E.A.1-597 mm bead seat)tires.
