I have a another non folding R20 frame, (to match the Wasp), just waiting to be built and most parts as well, here's my problem, (ok, one of my many problems :rolleyes:)
1: I have a set of Velocity 406mm wheels already laced, the rear has a SA 8spd hub and I'm looking at welding on Vbrake bosses to upgrade the brakes. This would be a lovely bike, but everyone is doing this size rebuild.
2: I also have a set of 24" Velocity rims, a new Shimano XT front hub, I could use the SA 8 spd for the rear, I have a 24" threaded fork which is slighty shorter in the steerer than the Raleigh but I can shave a bit of the head tube to make it fit. The rear of the frame only needs the brake bridge moved up and as I will be using narrow tyres clearance shouldn't be too much of a problem. I would be using Shimano road calipers for brakes.
I'm thinking, black frame, seat post, head stem, bar tape, saddle, fenders, pannier racks and spokes to set off the shiny metal bits.
Any opinions welcome.

I'm in the market for a 650c rim to see if that will squeeze in the rear of my non-folding twenty that's hiding in the shed. It looks like it will... :)

I got a 559 mountainbike 26" wheel in the back of my other 20.
No brake bridges on it at all.
But didt build the bike up completely.

That'd be cool but don't go out and do it specially on account of me. I love the idea of a garden where you can just chance upon bikes you'd forgotten about!
I took a tip out of Jur's book today and bought a butane blow-lamp to get the battleship-thickness paint off my non-folding Twenty - What fun - point; wait till it bubbles, then swoosh with a wire brush and it's all gone!

My newly found Raleigh 20 doesnt have a stand mount.
Is there any reason for that.
Whats the dating from the frame number.
Its got curly lettering on the 20 sticker.
Think my modded 20 is in the silver shed. was battling with all the wheels in there.
Found a Raleigh Mixte...well it fell on me.
So I went to play with that.

"If you go down to the woods today, you're sure of a good surprise,
If you go down to the woods today, you'll find one of alecw35's bikes"
Serioulsly though, if I have to cut the head tube to fit the 24" fork, should I cut from the top or bottom, or equal amounts from both and why?

Id measure the height of the bearing race on the fork crown.
So you can get the same height with the new front end.
Is likely that youll need to cut the bottom of the headstock.
Also Ive managed to fit a 26" MTB wheel into 24" forks

I think from the bottom so you don't end up lifting the front up too much and increasing the rake.
The rear of the bike will be elevated only by as much as the wheel is bigger - as the axle is still placed in the same spot whatever the size of rim, but a bigger wheel on the front in a longer fork will be raising up the front of the bike; Technically - if you are using 520 rims instead of 406 then it's rising up 57mm. (114mm divided by half the wheel height)
That would be the optimal amount to remove from the bottom to retain a similar geometry, though there isn't enough tube protruding below the downtube to allow this much trim; A quick look with a ruler on mine says you'd be good to remove maybe about 28 mm from the bottom; any more and you are intefering with the junction of the head-tube and down-tube.

Theres only 5 or so frames in there and a whole lot of wheels.
Nothing thats Raleigh though
Heres some of the wheels outside it.

But thats no reason it wont be there.

There was still a dozen or so alloy wheels still in there. Along with a few mag wheels.
Also on my shelving was a bunch of computer stuff...Zx Spectrums mostly..proper computers.
Have to move all my other wheels into there too.

One day I went in my back yard and there was a R 20.
Didnt know where it came from.
It was a newish one.
Had flat tyres and a broken rivet in the alloy brake lever.
I pumped the tyres and pushed the rivet in a bit.
Was riding it a few times. Did a couple of 25 mile rides on it.
Turns out it was my neighbours old bike.
He gave me other bikes. A pair of RSWs and a Raleigh Burner Mark 1 with fancy bits on it.
Its now in my old green house.
theres 4 complete bikes in there and loads of frames.
Then out in the yard theres at least 20 complete bikes. And loads of frames.
Got about 20 bikes in the main garage too.

I tried a 24" mtb front wheel in the front forks.
but there just a little bit short.
same for a 24 X 1 3/8 wheel.
tried them in both ends. Would have to change the forks and move the bridges on the rear stays

as it has no brake bridges.

For WeePix: I'm impressed that you are now tooled up for this sort of metal work. Good luck with your modifications. Re: the headtube and for the record: I took about 3/4" off the bottom of the head tube. Without getting out a measurement device, I took just enough off to remove the fork steer limiting tab. I may have taken twice that much off the top. Driven by appearance, I was trying to get good proportion above and below the existing headbadge.
I boxed up a 24" lightweight fork from a Terry bike sometime ago and never shipped it. Do you still want it? best regards, -- Retro Guy

Ive got a 26" stainless steel roadster rim on a AB 3 speeb drum brake hub.
That would probably fit.

I'm thinking the 24 inch wheels are the way to go, it has to be a folder, and think I have a solution to the rear brake issue too... now I just need a folding Twenty frame that is unworthy of restoration.

Looking at Alec's pic of his shed and ALL those wheels etc, reminded me of an old guy I met on a local bike path about a year ago. I was on my R20 which he reckoned was nice and I stopped for a friendly chat. Turns out he used to collect all types of bikes, fix them and hand them on to whoever needed a bike. He wanted someone to take over from him and continue the good work, but nobody was interested, so he took them to the tip with trailer loads of parts as well.
After meeting me and seeing my interest in R20s and older bikes he said he wished he had met me at that time because he would have given them to me.......all 350 of them!!
Can't decide between a SA 8 spd hub or a 6 or 7 spd cassette with 2 front chain rings, (53/39), for the R24, opinions welcome.

05-01-08, 10:14 AM
Yeah used to have a load more stuff.
The loft was full of old roadster frames.
There was nothing rare or my size. So I cut them up and filled my wheel barrow up with them and pushed to the skip/ dump.
They were all damaged or fairly rusty.
I was doing some work on the 20 frame today.
It might get scrapped too. As its very rough.
I had modded it already. I cut the top of the head stock, so could fit modern forks.
And have narrowed the BB so it takes standard axles.
Heres a pic from its last build up. About 2 years ago.

Yes, I've noticed that Jur has had trouble with his hub, but mine is a different model to his, it's a xrf8, highly recommended by Sheldon Brown, who said it was one of the better of the new generation hubs.
Maybe there's no difference and Jur was unlucky??
There's a NOS Sachs 3x7 hub going on eBay right now, does anybody know what they're like?

Mine's a XRF8.
I'll be taking it apart again this weekend to have another crack at it.

OK Jur, I was wrong there....sorry.
So far my problems with these hubs are minimal, mainly tuning, maybe you got a bad one???
And I don't ride mine in the wet anymore, that's what the MTB or the steel roadie is for.

I'm thinking SS...
I do have a 9 spd hub converted to a 13t single spd that I used on a R20 clone, I used a 58t front chainring and got plenty of speed from that set up.
...so there I was contemplating the R24 build, when "my dearest" informs me..."NO you can't use my R20 for that rebuild, I want it back to original....with the 8 spd hub!!"
Wanting to keep the peace I now face a few choices:
1: Do I give her the 451 rims with the SA 8 spd from the Wasp and pull the new SA 8 spd from my 406 rim to laced into the 24" rim and make the Wasp a R24?
2: Do I hunt around for another R20, (which are not easy to find here), and use that for the R24 project and give "my dearest" the 406 rims, make some changes to the brakes and keep the Wasp as it is?
3: Find another R20 and give that to her?

I tried a 24 X 175 tyre on a wide steel wheel in my 20 frame. It rubs on the stays.
So it looks like a 24 X 1.5. Have to find the wheel.
But I'll try my other 26 X 1.5 tyre in there. I tried my MTB tread tyre in that size. But it is damaged.
So try the slick tyre.

I have been trying to get the frame in decent order to build the bike up.
Hate prepping frames.
I tried a pair of 24" Raleigh MTB forks on it. Older ones that arent as long as suspension forks.
They made the bike really high.
So I looked out the forks I had on my silver Raleigh Phaser.
There off a 24" wheeled racer...not a expensive Time trial bike.
There a little bit shorter than the MTB forks.
I fitted them to the frame. Put a 100mm Sakae stem in there and some bars from an exercise bike.
With a Weinman 610 centre pull brake operated by a BMX lever.
http://i29.photobucket.com/albums/c296/Alecw35/twenty4.jpg
The bottom bracket is very high at 13". Most bikes are around 11".
I had a Raleigh Dirt Cross that had long forks. Its BB was high. Was difficult to get on to it.
http://i29.photobucket.com/albums/c296/Alecw35/Dirtcross3.jpg
Theres it beside my Grifter.
I suppose downhill MTBs are really high as they have long travel suspension.
LittlePixel
05-20-08, 02:07 PM
Yours is looking at pretty much the same stage as mine!
Yes - the BB is pretty high at that height - this is a hack after all. Mine is getting some 24" road forks from a 'Terry' petite women's bike (being provided by the wonderfully generous Guy Retreau) but for now the test fitting is with a 500a fork from a Pashley trike. It's nearly...almost big enough - just a teeny bit of grinding and it'd fit. (pics in my own 'build' thread here (http://www.bikeforums.net/showpost.php?p=6729825&postcount=11))

I got a brake adaptor plate from ebay
I first seen one of these in a bmx mag.
Its a thick steel u shaped plate that has brake studs on it
has a hole to put in the brake bolt hole.
then a place for jubilee cilps at the end.
so will try this on my 20.
got other screw in brake studs. They are from alloy mtb frames.
so might copy the brake adaptor plate for my other bikes
