After Hours - Bahnrad

Pleasure, I'm thinking to work on it on the weekend. Seatstay cutting, final fit up, tacking and brazing on Saturday, filing on Sunday and squeeze in the finishing work next week

Wow, what a steep learning curve and progress. Congrats, looking forward to the bahnfresser!

How long a stem are you going for?

Yeah it’s been steep but satisfying and quite an adventure

In the range 120-140. It will initially be 130. I ride a reasonably aggressive position on the road and only do mass start races on the track, maybe a few crits on it too. I designed the geometry so that I could replicate my road position but still have a lot of room to move forward on the bike.

I’ll take the selection box to the track and experiment then, when I’m happy might make a steel bar stem combo

That sounds like an outstanding idea

Only got to the workshop for a few hours this evening but made some progress (had to tack up a customers frame first to clear the jig).

Seatstays done, angles refer to s/stay relative to dropout and s/stay ST

Looking like a bicycle frame!

Stoked on the TT, ST, SS junction, think it’s gonna look sweet filletted up.
All mitres freestyle hand cut (except for CSs- BB and dropout slots). Partly due to necessity - tubing profiles and tooling, partly because it’s a labor of love, a chance to do things differently and challenge myself.

A little detail just for me

That seatpost is going to be...

Yup, fat too! 31.6x410 Thomson in the post

Seat tube top cluster will be wicked.

I tried to do one here, but not as clean as yours will be. I was heavily inspired by Caad 10.

I have this result on my Reilly. At first I couldn't get past the aesthetic, now I love it.

Looking forward to seeing how this turns out.

Looks sweet!

Let’s see it....

yee! nice read!

Without mega stress and ridiculous after hours this was never gonna he ready for race day...yesterday...so I spent a bit more time on details rather than just hammering in together

Wasn’t happy with the seatstay/dropout junction form in fit m-up so added some more material to the dropout to be able to find a nice shape

Before:

After:

All clean and ready to tack

Update pls;)

It’s track bike shaped but not yet finished. I’ve just been doing bits here and there when I’m in the workshop early doors.

With the turn of the seasons motivation to be riding outdoors has diminished and motivation to work on projects has increased. Plus I gave my track bike away in summer so really needed to get this finished. I pulled it off the shelf and dusted it off and realized really how little work was remaining so found of few hours over the week to get it done.

First up brazing on then cleaning up the seat clamp and stainless dropout faces.

These before pics also show the sculpting work I did on the dropouts and stay junction.

And after cleanup and reaming the seattube, slotting

And the last small wee job was brazing in the integrated headset cups

Finished!

Aber light it is not

Build mock up:

And from here it goes to the painters...he's been given a long leash but the rough brief is loud, bright and no tone-on-tone graphics...excited to see what he delivers!

The bit we were all waiting for! The rest is not bad either ;-)

Thats one fine whip!

Damn that's a very long leash indeed, looking forward to see the results.

Looks super nice. Seat tube cluster is on point

This whole thread is great. Looking forward to the results!
