Earlier version (June 2018):

As I just updated the wheels and managed to take proper pics of the bike I though I’d share this with you.

This is my weight weenish singlespeed bike for road riding (not racing). It's built around a 2003 Scott AFD frame using parts I have collected over a long period of time.

I remember lusting after this frame for a long time but in 2016 I finally found a complete bike from France. The bike was caringly built with full DA 7700 groupset (including carbon tubular wheels) but I have to admit I took it apart immediately after receiving it and sold all the parts as I only wanted the frame!

The frame is somewhat different from Team Issues that I've seen: seat angle is surprisigly slack at 72° (needs a 0mm setback seatpost) and the rear brake cable housing stops are on top of the top tube. Also there is a small welded tab under the top tube to fasten race number to. I believe this could be the actual frame Gilles Bouvard rode when in Jean Delatour.

The build has gone through different incarnations of which this one with flat pedals (!) is the most relaxed. The bike was almost 200 grams lighter with a Chinese full carbon saddle and my Look Kéo Blade 2 Carbon ti pedals but I have to admit my behind is somewhat used to those old school Flites. And the flat pedals make the bike very easy to just grab and ride. Works great for non-performace types of rides I mainly do.

Total weight is ~5.95kg.

That's it. Not very much money was spent on this (from memory 800–1000 euros all in, my laptop broke so I don't have the exact figures anymore) but I'm satisfied with the end result. The weight is good, it rides very nice and I don't think it looks that bad either.

So I like it, hope you like it too. Thanks for watching.

Very nice! How did you get correct chain tension? Just playing around with chainring and sprocket sizes?

Cannot remember anymore but I think I measured and then looked it up.

Found these pics of the time when I measured my Klein frame to get the magic gear right the first time.
Image

Allen key taped to the rear dropout. Sharp edge towards the bottom bracket. Measuring point (90mm from the frame centerline) is marked with a felt tip pen.
Image

7mm wood drill fit nicely inside the bottom bracket axle. Drill is also taped so that the tip is at 90mm distance from the frame centerline.
Image

I used a steel ruler, measured the distance from the edge of the allen key to the center of the tip of the drill. Then added 5mm.

Magic gear calculator can be found here: http://eehouse.org/fixin/formfmu.php
