(Not terribly helpful) Raleigh 20 fork option.
My Twenty has been sitting in pieces while I focussed on keeping my other two bikes running. But last month my Tote/Cycle came down with a terminal case of cracked bottom bracket shell, so I started looking at how to get the 20 running as my spare bike. Front fork wasn't working for me and it came to me with the original headset missing, but with a threadless headset the previous owner never got around to installing. I'd like to, and probably will eventually, go the route of the generic Pyramid fork with an extender, but I really wanted to get it running sooner, and it occurred to me that if most forks were too short, that was probably not the case with my Tote/Cycle.
Threadless headset + my Tote/Cycle fork + a 1" seat tube clamp + my Tote/Cycle's quill stem, and I'm in business. But it looks a little goofy. The yellowish section is all steerer tube extending above the headset. I guess I could raise those handlebars about up to the moon.;)
Plus, I think Tote/Cycles are a little harder to come by then Twentys, so tracking down that fork might not be a realistic option, but you never know.
