The 3-speed fixed gear sounds like fun.
The new one is not available separately yet, is it? And I bet it's expensive. |
I also like the decision that Sun Race made when they decided to give the S3X a wider range as it makes it pretty versatile... have been trying to find out what range of cogs they are offering as these are not interchangeable with anything.
I would not be happy using a 12 or 13 tooth cog unless it was on my folder... ;) |

This only speaks to the drive's efficiency... a wider gearing range can make a rider more efficient even if the drive is not. bikcamper, great link!, I really enjoyed the tech article by Jim Gill.:thumb: |
Beautiful bikes. One thing I miss on BF because I don't look at the vintage section much is just old fashioned, solid, reliable bikes. Nobody made this work in the 20th century quite like the British did. Perhaps the Italians perfected the racing bike, but the British perfected the everyday bike.

But my initial reaction is that the gears are too far apart. That is, I really miss the close ratios of my Sturmey Archer 8 speed hubs. I'm sure I'll get used to it, though. Photos to follow! |

The new S3x uses a 9 spline pattern (like Shimano cassettes) but have been told it is not compatible with Shimano cassette cogs... thinking that it might use 9 identical splines like the old Uniglide.
I will have to look up those cog specs although one would not want to run a ramped cog with shorter teeth on a fixed drive anyways. I'm fairly certain that Shimano BMX cogs are also compatible. These appear to be the same quality as the Sturmeys but may be more readily available in your area. |

The new Sturmey Archer 5 speed wide range hub has the same ratios as the AW plus a super low and a super high. The gearing is:

Tell me, please, Bicycle Repairman, what you know of the Raleigh Tourist.
I bought one here in UK, blue with white head tube, scruffy vinyl Brooks ( ? the low point of Brooks' history), 26" wheels with Westrick rims (very rusty), Sturmey 3 speed (which aint working properly and needs dismantling and cleaning), front dynohub, and all transfers present and "patinated". So it is pretty original. And man, is it heavy. I was planning on doing it up but haven't yet. In 4 months I return to NZ and I am trying to decide whether to ship it home or sell it on But I am in the early throes of the Disease, and I can still recognise my problem. So I am trying to stop it getting to marriage-threatening proportions, so I may sell it here in UK All this talk has got me out in the carport to check my hub. The Trent Tourist has a SW hub, dated 58 6 , so that makes sense. I bought in off ebay for 40 quid and was told it was in 'good working order', but the gears slip! I have done nothing to it over winter, but was planning on pulling hub apart and cleaning it. But now I have read the negative press about the SW, I am wondering what is the best plan for the old bike This bike |
Where exactly does one find a Benelux conversion? I've been looking online, and just about the only place I can find it is that there is one on Ebay for $200...I'm not spending that much for 3 extra gears.

Doing the math I would have 9 unique gearings with 10% jumps and a gearing range from 42 to 91 gear inches as I cannot change the cyclo triple cogset from it's 19/21/23 and they also made a double conversion. A lower cost solution... 2 Shimano 3 speed cogs can replace one SA cog and one could use any decent deraileur for switching duties and in this way you have more choice in cogs. With a 2 tooth jump the spacing between the 6 speeds is 10%, with a 1 tooth jump it is 6%, and there is no gear duplication... shifting one of these takes a little practice if you want to sequence the gears but I treat them as a high low range. |
How does one do this? Put the sprockets on opposite (so that the dish separates them)?

I think one of my problems with three-speeds is that they're too reliable. They don't require enough tinkering from me.

I really regret selling off the one 3 speed I had. Regret not pulling the trigger on the Dunelt I found later.
One of these days I'll find another English 3 Speed and have another project. Beautiful, practical bikes. |
politicalgeek, you will find a good English 3-speed. Just be patient. Some are going for well over $150, which I won't pay. I got mine a couple of months ago on Craigslist, for only $60. It was hardly ridden, has chrome fenders, and everything on it is original. Lie down like an alligator, watch, and wait.
|
It'll come, I know. My luck with CL is that I usually find stuff when I am ready.
Working on a bent and within 3 weeks I found 2 excellent donor bikes for $50 a piece. Been giving some thought to making my Schwinn Le Tour a single speed. Sure enough a 27" single speed wheel set shows up on CL, and 2 days later a crankset and new tires. I'll probably troll ebay for a frame. I have a NOS SA hub and it would be fun to build it up from scratch. |
AL NZ- You may want to look into pulling the SW mechanicals from the hub shell and slipping in an AW gearset in it's place. Should be a fairly straighforward swap. I think Sheldon Brown or Tony Hadland had info on doing this. I put a FW into an AW shell until I got new wheels built and the FW worked just fine. Hopefully you will have the same results. PG.

This is such a great thread! So much useful info, I had to print and save some of it.
Thanks for the kind words on my bikes a few pages back as well. |

58 6 would be late in the production run so Al may be OK if he strips his hub and thoroughly cleans it. SWs could not tolerate anything sticky on the pawls. See; http://my.ohio.voyager.net/~bdhayes/sa/sw.htm for good info. |

What an awesome thread and some wonderful bikes! Somehow I missed this one.
Here are the Three Speeds that I have. 1948 Rudge Whitworth Sport with dynohub I haven't done anything with this one yet. http://i914.photobucket.com/albums/a...01948/RWa1.jpg 70s Raleigh Super DeLuxe Haven't touched this one. http://i914.photobucket.com/albums/a...IMAGE_0191.jpg 1973 Raleigh Twenty with my wife "Englished" Dahon The old Englishman that sold me the 20 has found the chainguard. I am going to pick it up tomorrow. http://i914.photobucket.com/albums/a...n/IMG_6278.jpg |
Sixty-fiver, there are days when I hate you...You make me want to add a 3-speed to my collection, and I'm trying to save money for other things!
The worst part is, a "60s vintage CCM" is up on used-vic for $140.... http://www.usedvictoria.com/photos/01/68/12871268.jpg I wants it...but I don't think I can swing it right now. |

A younger fellow on a 70's Peugeot was pretty intrigued with the bike and the three speed and didn't know what that shiny steel ring in my hand was until I clipped it on my pant leg... cause if you ride a vintage bike you need a vintage pant clip. :lol: The cog change worked out wonderfully and got to test the low on a short 12% grade and did not even have to get out of the saddle (legs were working good) and in high gear the bike is remarkably fast... I will put that down to a fairly aero position and tyres that roll fast and suck up bumps like they aren't even there. Like it's sister the Lenton, it climbs very well too. And the only noise besides the ticking of the hub is the occasional "sproing" from the sprung kickstand when I have hit some really rough stretches. |
Oscuro - I know a fellow here who got a nearly mint Raleigh Superbe at a yard sale... he paid $20.00 for it and the best part of the deal was that there was a ladies version selling for the same amount which he snapped up for his fiance.
A bike like that in this market will often sell for $275.00 plus if it has been tuned and serviced properly. More pics... so you can hate me more. http://www.ravingbikefiend.com/bikep...orts6sepia.JPG |
