Invest in a R20 folder...wtf!!!
 
Because when your done and spent you've got a finished bike that rides like a nippy road bike, thats unique to you and that connects you through deep technical intersections to an incredible UK cycling legacy...and is basically a bike friday with a shorter head tube and less steel bracing...

When the geek overtakes the freak you know you are riding a bike that makes sense!!!!

That's my Silca frame pump, off of my regular road bike. Haven't trimmed it down, just wedge it in where it fits. r, Guy

They are ISO 520 wheels. That's why I call it a Five-Twenty. I'm running a 60T chainring with 16T or 17T rear depending on the wind. The larger wheels give me a touch more bottom bracket clearance which the Twenties generally could use. This has become a retreau variant of the Twenty similar to the current day Airnimal Joey. r, G.R.

What kind of breaks are you using and were they easy to install?

I'm using a 24" time trial front fork with short clearance sidepull brake, recess mount bolt.
In the rear, I cut and ground off the original brake bridge because I didn't like the way it looked.
Brazed in a new brake bridge from 4130 tubing I purchased online. was able to set the rear clearance
just where I wanted it for the short clearance side pull. Reversed the anchor bolt and housing stop to get a better orientation for the brake cable.

The other peculiar thing is I rebuilt the chainstays from an old juvenile Peugeot fork blades. The fork blades were heavier cross-section and provided a transition from round tube to wide oval. At midlength the chain stay tubing is butted with a full internal sleeve and then brazed. At the BB, the forkblades were shaped to fit the BB shell and then fillet brazed all around. I debated about using a chainstay bridge and decided to go without it. So far, no worries.
