OK, so most of the bike went together yesterday, a few minor things taken care of this AM, and it is done!

Before:



As received from Dynocoaster who started the previous thread with a query about anyone wanting to build up a S2C R20. Crank was rusty and bent, bb dry and notchy, headset was typical plastic bushing. Seat tube was a bit beat up by the clamp area. Not a mint frame by any means. Perfect for a conversion rather than a restoration.

To make this work, I scoured various R20 projects here and on the R20 forum -- none of what I did is at all revolutionary, most if not all mods have been done by others.

After:











Some detail shots:

Race Face BB -- dusty backroom bikeshop score:


Build went surprisingly easy, just needed a solid day's work to get it all together. BB re-threaded so standard English threads and bb shaved down to 73mm. Now any standard BB will work, but we happened to have that lovely Race Face unit languishing at the shop -- no lip on the right side cup, so there is driveline adjustability there.

Cut the headtube down by 23mm, which turns out to be a bit aggressive, but nothing that can't be solved with some headset spacers. This facilitated install of Ritchey Logic threadless headset upper; kept the stock lower because races were fine and of course the new crown race is too small for the Raleigh standard fork. Added a clamp south of the original quick release for good measure. Steerer extension is a BMX seatpost, upper part is 27.2, with a shim at the stem to fit the 1-1/8 stem.

Seatpost is Kalloy, unremarkable; saddle, stem, and handlebars are all Bontager items... yes, I work in a Trek shop. Brake lever is an old flat lever off a city bike, beat, aluminum, but works on this bike. Crank is Bontrager SS, like you'd find on a Trek Soho S.

Drivetrain is 44 x 17 -- with the S2C hub out back, this gives me gear inches of around 43 and 65, a decent cruising gear and a low gear for hills. Wheels I detailed in a previous post; tires are Schwalbe Marathons.

Had this set up with traditional brake cable routing, but with the headset setup, it's a straight, unobstructed run right from top to bottom, so why not route the front brake cable through the stem/headset/steerer? Yes, I can haz barspinz!

As is, this is more a separable bike than a true folder. But so much fun. I've only tooled around on it for a bit, so a longer ride is soon in order.

Wicked fun build -- thanks, Dynocoaster, for the frame and impetus!
