One of the guys on my flickr foldr group was musing on the idea of transplanting the rear triangle off a light old roadbike onto a twenty as some sort of compromise. An idea with legs if one can braze weld non?

It should be noted the oval-framed 'New' Raleigh Twenty has an aluminium frame, but if the quoted weight is anything to go by - it's cast solid in a die.

I have been following along with the un72 bb swap out and I have read the external links talking about doing the swap but does anyone have step by step photos of what exactly the procedure is? My brain just gets confused every time I delve into this topic.

What for? There wouldn't be much of a weight saving, and such an effort is hardly worth it just for the dropouts...

When looking at weight, you really have to look at everything. Wheels especially. Even the heavy R20 frame has been made into relatively lightweight bikes.

That image of the orange/black r20 - that orange looks exactly like the color I am going to paint my frame. I am planning a metallic orange, slightly paler than vivid, with all the other parts matt black.

Is that a real R20 or your musings with photoshop?

With all these R20 musings...about clones and whatnot, I have a 24" frame very similar to a R20 but with horizontal dropouts, ideal for a hub geat set up. Also in my shed I have just waiting to be used a lovely new set of 24" Velocity deep V rims....now I'm thinkin' to myself....why not make up a great little tourer from this?

It has 24tpi bb shell, a threaded steerer and more cockpit room, what do you guys think?

I'm still considering what to do with mine. I'm riding it regularly in largely stock condition, but one of the cranks has developed some play that I can't get rid of by pressing the cotter further in. I'd really like to go cotterless, but I don't think I want to drop £100 on a Phil Wood BB for my £20 bike. I wonder what retapping would cost......

Definitely also tempted to build a wheelset with velocity rims and a Shimano Nexus 8, but we shall see my children, we shall see. Of all my bikes, it's the one that's least likely to ever be "finished".

Sammyboy- Cotter pins are cheap and the job of replacing one does not take a whole lot of time. Replacing the cotter is just a lot less expensive than replacing the bottom bracket. May be best to do the quick fix until you know what is in the future for the Twenty. Oh- even though they are heavy the old chainring stamping is pretty, the three herons that is.

Better steel I guess!?!?!?

Hands up - it's more photoshoppery. I think a two-tone frame would rock though. How about different fronts and rears for the mix-and-match approach! 1-2-3-Accessorize!

Actually, a two-tone frame is what I plan on doing with my R20... Not too sure about which 2 colors to use yet though. I saw a two-tone R20 and yep, it does rock.

To get back on topic... I'm still searching for a UN72, and might have found 2 actually. One is 68mm and the other is 72mm. What is the better one for an R20 application?

Thanks,

TB

stevegor

The 73mm is the one to use if you are leaving the R20 bb shell at 76 mm, the Phil rings will be recessed about 1.5mm each side, give or take for chainline etc.

Say Time Bandit, perhaps you might want to give the Kinex BB solution on my page another look. After all if it fails you are only out 20 euros or so, or are the BB's you are looking at cheap?

Just a thought.

+1 Buy the Phil Wood cups for your UN 73, buy one or two Phill Wood tools to instal it or have LBS do it.
Ralkeigh 20 BB shell is long. you need a longger bb spindle to go with, Heard that some dudes shave the sides down of the bb shell, p.i.t.a i. m. o.
