The answer to this question generally depends on rarity, age and condition. Nottingham Raleighs were built in huge numbers, and they were so well-made that quite a lot of them kids dh bikes survived, so most of them raleigh 3 speed parts really qualify as "rare.
Very few English bikes were imported to the U. That said, I'd generally consider anything from the s onward to be fair game, with 50s bikes on the borderline. I have a separate page about dating your Raleigh bike.

Hot-rodding or otherwise modifying them was a popular avocation, and perfectly reasonable at the time Larts information on servicing the stock cottered setups, see my articles on:.
By far the cheapest option is to keep the original 26 TPI Raleigh cups, and install a new spindle raleigh 3 speed parts the tapered square ends needed to fit cotterless cranks. Bicycle shops do not usually stock these sizes, hybrid womens bike Internet vendors carry them.
You must check the bmx bkes of bottom-bracket spindle, bearing balls and cups before installing the bottom bracket. If the bearing tracks run too low on the spindle, the bearings will wear quickly. Place some grease in the bearing cup, then assemble the parts, as shown in the photo below.
Rotate the spindle, then take it out and examine it. The next image shows the bearing track too low, as is usual with a JIS spindle and Raleigh cups.
The bearing balls actually ride on the little raleigh 3 speed parts on the low side of the bearing area of the spindle. Ralleigh also pushes the bearing cup outwards and can deceptively look like a good fit in a wide Raleigh Twenty bottom bracket.

You may check whether the assembly is wide enough by holding it up next to the bottom definition bicycle. The combination that seems to work best is a 7 series spindle with 6 mm bearing balls, in a 71 mm bottom bracket.
Raleigh 3 speed parts could also install a crank loosely to run a quick check on the chainline. Just getting a spindle to fit into the frame is a start, but you may still have problems due to the overall length of the spindle. Older cranks used longer psrts than newer, "low profile" cranks. JIS axles are mostly available in longer overall lengths, which are likely to give poor chainline with newer cranks, though they will work.
If you are spreading the rear dropouts of a frame to use a wider hub, you may want to increase the chainline anyway. See my article on Bottom Bracket Sizes for information on spindle lengths for different cranks.
Modern cartridge bottom brackets are much easier to arleigh than the old-style cup-and-cone design. There are three possibilities for running a cartridge bottom bracket in a Raleigh 26 TPI shell:.
