Old Raleigh frame... build up question / cottered ??(4 posts)

Old Raleigh frame... build up question / cottered ??suedehead
Jun 10, 2003 12:22 PM
hello -
today i aquired a 1962 raleigh gran sport frame and fork in nice condition for $40.

it comes with a bottom bracket (w/out bearings).. and it is cottered.

i'm most likely going to build this up as a single speed since that will be the least expensive way, plus i love single speeds.

my question is... cottered cranks. will this be a pain in the ass to find?
can i just take out the bottom bracket it comes with and replace it with a cotterless crankset, or will there be compatability issues?

thanks!

You should be able to find a nice Stronglight or Nervar cottered crankset set on Ebay. The problem is that there are French, Italian and British standards, and it's pretty hard to know if it will work until you actually try to build it up. You could use a a standard Japanese square taper axle in the cups you have, or get a Shimano bottom bracket, and use either one with a Sugino crank. That's what I did with my fixed gear, just because I was tired of scrounging parts. Shimano BB's come in lots of widths, so it's easy to get a good chainline. Also, lots of older Ralieghs have non-standard bottom brackets. ISO standard is 68 mm wide, Ralieghs are 73mm wide and have different threads. If you have one of those, you'll need to keep the cups and find an axle that works.

Harris Cyclery, which you can reach through www.sheldonbrown.com, is a good source of stuff like that. www.loosescrews.com, in Oregon, seems to be dropping its inventory of old/weird parts, but it's worth a try, too.

Many old Raleighs used WHITWORTH threading, which is totally incopatible with any other type of thread. Better check this out, before you plunk good money down on a new BB.
