Cupcakes fabrication

Time for another of these threads.

I've had a few. First was the crosscheck. Then the Rychtarski road. Then the Armour sparklehorse gravel bike.

I feel like I've learned a bit about geometry and my preferences for riding, components and so on. But as an engineer there has always been a desire to build something myself. Currently studying for a PhD, I loosely planned to look into the Bicycle Academy once I finish my thesis, but now the research is in a Covid-related extension period and the Academy is on hiatus.

Then a local builder said he wanted to start framebuilding classes and needed some test students to get started with. I volunteered right away.

The plan

All steel road/audax-esque bike.
700x38 with guards.
Geometry fitted to me, of course (based on the current position on my Armour gravel bike, which is currently set up for road use - this has been confirmed through bikefit).
1*11 mechanical Sram Rival with flatmount TRP Spyres (because I have this kit already, and more importantly because I find the hoods to be very comfortable).
Provision for internal dynamo wiring.
Columbus Life/Zona mix, with skinny seatstays and top tube.
EC34 headset, straight steel steerer, steel straight-leg forks in a lugged crown.
Through-axles front and rear.

To be continued.

Exciting

Here's a BikeCAD outline.

I've already reviewed this with the instructor and the tubes, dropouts and sundries have been ordered. So if you spot anything untoward, do please be constructive when you point it out :)

Nearly subscribed until SRAM

Colour is shown based on @BassoBry 's excellent Bridgestone. I could also be temped to go for the BlueGrey as seen on my old Rychtarski.

Sweet, subbed!

Looks spot on to me

High praise indeed, thank you.

I forgot to mention, this will have king iris bottle cages thanks to @swedeee

But so wrong for lfgss self designed fixie skidder bike fit which is when we end up with bikes with T-Rex geo or stupidly long top tube or some other aberration from self diagnosed bike fit problem or a weird head tube angle or chain stay length to give a pointless handling characteristic.

It looks perilously normal, which is a good thing.

Heh, I think I've worked my way through/around most of those perils in the previous projects...

Dibs;)

Exciting!

Very excited for you!

1 1/8 head tube?

did they arrive? :--)

They sure did!

Yes!

This is going to be lovely.

I agree those rival shifters feel so good and look so much less ugly than hydro brifters of all varieties

Exciting!

Hoping to see some nice workshop photos.

This is really lovely, so many great features.

But also followed and looking forward to seeing this develop

What’s the timeline so that I can stop compulsive checking the thread?

Building will commence on 9th February. Unless I get injured (crosscheck build) or something gets damaged by couriers (rychtarski build) or some of my intended details are borderline impossible to actually make (armour build) :)

There should be a steady influx of parts to whet the appetite over the next few weeks...

Thanks all for the kind words. By the way @cheekysnaker yes it'll have a 1,1/8" steerer tube.

Today I purchased:

Cane Creek 40 EC 34 silver
Deda RS01 seatpost silver
Praxis Works M24 bottom bracket

steel straight-leg forks in a lugged crown

Just re-read and noticed this. Awesome. Why not carbon?

edit: to add, I dont think it should be carbon, I'm just interested

Looks nice. My kinda build. But 38c is gonna give you hella toe-overlap with those dimensions. If you really want to run tyres that big.. extend the top tube, slacken the head angle and increase fork rake to 52mm … and maybe a shorter stem
