After Hours - Bahnrad

Wow. Update was worth the wait!

I always found tt style saddles worked well on the track so I’d assume the more modern short saddles would work equally well.
I always found a slightly grippy top was important too otherwise the g force and sweat starts to slide you off the seat

sick!

Nice, thanks for the feedback!

It was a little cobbled together before but took the time over the Christmas period, as the track was closed, to build it up properly, chop the steerer etc

I've just been riding the last few years but getting back on the track on this has totally lit a fire under me for training and going quick and I've been absolutely loving it! Just what I needed to get me through the Berlin winter!

Amazing bike!

Went for a Fabric short nose saddle and it's good! There's no sliding room but I can roll my hips forward more and numbness issues are gone

I've been meaning to try one of those. Is it squishy? I wish my specialized power was softer

Yeah there’s not crazy padding on it but it’s squishy and I still didn’t feel it bottoming out…would recommend

Awesome build and paintjob (eventually!)

Ive read this whole thread ages ago - what was again the rationale behind the geo (sloping TT)

Have you, by any chance, purchased the chainring off of ebay from Munich end of 2021? =]

Wow that’s crazy good.

Thanks! The rationale behind compact geo in general is that the frame is both stiffer (while exposing more seatpost which can flex to give a smoother ride*) and lighter due to less tubing being used. For me there's a beauty in form that follows function and so build all my personal bikes like this.

Re.the chainring: my boss has been storing it for over 10 years waiting for the right candidate to come along...

*although moot here as a. the track is pretty smooth and b. its a 31.6mm Ø Thomson inline

Many thanks for those aspects, very helpful

I just sent that exact chainring to Berlin to a „Jan“ so thought that might have been a nice coincidence (but apparently its not ;-))

As its a 2x chainring, is it safe to be ridden on track with the teeth being optimised for shifting to the smaller chainring?

Gorgeous bike, the paint looks incredible close up and love the (probably wrong term) head badge

Ah man, i wasn't sure if i liked it on the previous page but it looks so good now you've finished setting it up. It's a little unconventional looking but i think that's a good thing. I have a similar frame with a sloping tt that i've been thinking of making a track bike and this is great inspiration.

Lovely to see a braze on clamp on a 31.6 post looks so good. Mine has an odd sized Columbus seat tube so i have to shim between tubing and collar and i think what you've done would make a much nicer setup.

This was well worth the wait! Love the detailed pictures:) the subtle Fern logo's are great and the one on the headtube is perfection

Oh and are the cranks painted, powder coated or anodised?

Thank you

Oh man that is a beaut. Dream geo for me (long torso/arms x stumpy legs)

Haha yeah would have been funny! The Dura Ace ring won't see much use - it's a 54 and I generally ride use 53 or 56 - sits handsomely in the rotation though ;)

re: the cranks - they're used/vintage that have been polished up and anodized

I looks forward to seeing it! Shame about that funky size Columbus seattube, I never understood why they make them, nor have I felt compelled to use one

I'm all legs!

The beauty of compact geo, just add seatpost!

Thanks re cranks (my rhyme for today)

Thinking about doing this to my 7710s

Can you recommend someone who can do it?

I‘m in Berlin and use an industrial anodizing firm, I’m sure there’s something similar in London but don’t know off the top of my head
