Cottered cranks should give you no troubles. When you disassemble the crankset you effectively destroy the cotter-pins, so have new ones ready. Unfortunately it seems that newer ones are much softer and poorer quality than the old ones. A friend dug up some NOS ones that had whitworth standard nuts, and they feel much more substantial than the ones you get today.

You've got to knock them out with a hammer if you cannot get your hands on a cotter-pin press. Support the crank with a hardwood block or a length of old steel seat-post (I happened to have one laying around just the right length). When you put the new cotter pins in you have to make sure they are in the right way. Insert the cotter pin from above with the crank facing toward the rear of the bicycle. (clear as mud?) I put a set in the wrong way around the first time (Murphy's law) and they were chewed up within a matter of days.

I greased the spindle and the cotter-pins a little to help them slide in more easily, and hopefully they will come out more easily when the time comes to pull the lot apart again. Some people reckon this is a good idea - it prevents the whole lot from rusting solid. Other people say it's a bad idea. At the moment I don't think there is much harm in it.

Thread revival time again. Just picked up a Twenty and wondering about where I might be able to source some new rims to replace the original steel ones. I've have a few old BMX rims but the size difference (despite both being 20") is significant, add to this that they don't match the 28 holes of the existing hubs and I think I need to find something else.
My preference would be to get a new rim and rebuild the wheels on the existing hubs.

Velocity seem to list both 406 (small BMX) and 451 (what I have) Fusion rims but I can't find an online source in Australia who lists them. Does anyone have any pointers? Also, what's the ballpark cost of a new rim?

Cheers,

Steve

Check out crc. Only thing is that free shipping doesn't kick in until your order over about $400.

Here's a rim that may be suitable. (Just the first one I clicked - look at them all)

I would like to get light new rims for my twenty too but it's not a priority atm.

I would like to get light new rims for my twenty too, but I just cannot afford it! I do have some Araya alloy BMX rims hung up somewhere - picked them up off council pick-up, 36-hole (I got hubs too), but cannot afford to pay for 72 new spokes and nipples. Well, not yet anyway.

I went into the LBS today and asked how much a new Velocity rim would be and was quoted around $90 per rim...I don't think I can afford it either. I too have some old BMX wheels but the size is so much different I don't think they'd work well - the BB would be too low with the smaller wheels and you'd get pedal strike too easily.

Looking overseas, one option seems to be the Alex R390 rim which can be had for around US$28 at various places including Amazon and eBikeStop and even in Australia at BMX International (a wholesaler - no price on the website - I've fired off an email to ask).

SeanB, didn't see the 451 size at crc, just the smaller 405.

So, it looks like it might be an overseas order if I'm to do this. Any other suggestions?

The ones I linked to are 451 sized.

so are these http://www.chainreactioncycles.com/Mode ... elID=42485

Shipping on an order of two of these is about $40 bringing the total order up to just under $100 for two rims shipped.

Sorry, so they were, not sure where my brain went. But the US versions are a bit cheaper, a pair of the Alex rims from Amazon comes in at A$75 delivered as far as I can tell. Not sure if one is better than the other, they weigh the same so I'd imagine little difference.

My folding Twenty has the 406 wheels. Stick with the short 165mm cranks and pedal strike is only an issue when cornering. I dare say that the bottom-bracket is at the same or lower height as most touring bicycles. It works out well for me, anyway, as I intend to turn my folding twenty into a poor-man's bike friday.

As you may or may not be aware of, my website has a different cover photo every month (though it doesn't necessarily get there on the first day of the month!)

However, I seem to have misplaced one picture. Does anyone remember what I had up for February 2010?

Thanks to Trevor Shone (Stackyard59) for the picture. I just wish that I could have made him an offer for it before it went on ebay. My mother and sister would have loved a purple one.

I don't remember what photo you had for Feb, but that is my Twenty in Savannah, GA USA that you have for April.

I picked up another cool folder project the other day. It isn't a Twenty, but it is still kinda cool.
It is a 1960s Graziella Italian folding tandem with 16" wheels.

Give Greenspeed in Knoxfield, Victoria a call. They had a heap of 451 and 405 rims being cleared out of their factory (amongst other things) about six months ago, though I've heard that Abbotsford Cycles may have bought most of the remaining stock

I picked up some stuff from Greenspeed to build up my sons bike.....

Image

.... a 3-speed, Raleigh 'twenty' (of sorts)..... :roll:

Also, check this thread out.....

EDIT: Just been to Anaconda in Bayswater, and they had a number of narrow ISO/451 Tioga knobbies and 16" Schwalbe Marathons for $25 each
God save the ABC & SBS.....

It's okay - I have only ever seen one for sale in Sydney. It has gone to a young lady who is having it professionally re-done. Stripped down, re-sprayed and personalised. She got it for only $65 too!

I had a lovely mint black one. I gave it away to a friend down the coast for his wife.

Thanks kingfish! I now know the brand of my folding tandem that I found thrown out. It is identical to yours!

Post a photo of your Graziella (or Grizzly as I have found they call them). Do you have the same ape hanger handlebars as mine?

If you go to my link on bikeforums ( http://www.bikeforums.net/showthread.ph ... ot-project ) you will find some additional links to some Grizzly sites.

My website just celebrated 6 months on the web. 40 links, about 250 pictures, and 60 members. And to think that I decided to publish my research after all the work and frustration it took to find relevant info on an otherwise forgotten 70's bicycle! I never realised that it had become something of a cult item.

I mocked up a Raleigh Twenty with drop handlebars as a sort of club-bicycle tourer type thingy. Anyway, this image has served as more inspiration than anything else so far to have a try. It's actually an F-framed Moulton 5-speed, but you can see what I'm getting at:

I recently underwent full knee joint replacement surgery. As part of my rehabilitation programme I wanted to get back to cycling, so I restored (well cleaned and painted) this Raliegh folder. I deliberately chose this bicycle, as with its step through frame it is easy to mount despite a crook knee. Further with its low centre of gravity I have found it to be very stable.
Image

You will note that the bicycle is quite different from the Raleigh shopper. It has an integral rear rack and no stay on the bottom bracket. The bottom Bracket is threaded not in the Raleigh propitery thread but uses the Italian standard with two right hand threads. The folding mechanism is also different. Does anyone know anything about this model. eg when manufacured and how many were made.

It has the original short cranks in this picture and they were of benefit originally as it did not take as much knee movement to pedal. I have since fitted longercotterless Shimano 105 cranks, but intend to use only the one (inner) chain wheel.

Take a look on the rear hub for a date code. I'm willing to bet that it's somewhere around 1985 to 1989.

When Raleigh discontinued the H-frame Twenty, they replaced it with U-frame bicycles like that. It appears that most had 22" x 1.75" wheels.

this isnt correct, if you disassemble them incorrectly you will, as in smashing them with a hammer, if you use a cotter pin press (or similar there is a thread on it somewhere) as your supposed to you wont need to bother with the new rubbish pins

Yeah, and how many people have a cotter-pin press handy? If anyone sends me one as a gift, I'll love them forever.
