Here's my latest creation. It's a custom carbon frame for disc brakes with flat mount calipers and thru-axles.
The frame weighs 1kg and the bike weighs 6.9kg without pedals.
The paint is based on an artwork by Jackson Pollock.

Very nice !!

But why the spacers and short stem for a custom made frame ?

It's gotta be for a smaller rider in the 150-160cm range. If the reach were any shorter you wouldn't get toe overlap, you'd get foot overlap.

Gosh-darn that's a good looking paint job though.

The owner is probably well under 5' (150 cm) tall. thus the resulting slope of a shorter top tube and taller head tube would probably exceed the limits on effective bonds with tube-to-tube construction techniques, not to mention that if the top tube were any shorter, the toe-overlap of the front fork would end up being pretty precarious at slow speeds and technical turns.

The short stem let's me preserve a good front centre figure to avoid toe overlap without resorting to a lower HTA and increased fork offset. The result is good steering on a small bike. I've learned these things from my own experience of riding small frames.

This particular rider is building up his form after some time away from cycling so the 15mm of spacers allows him scope for lowering the handlebar in future, either through a change in flexibility, a desire to be more aero, or a change of saddle or pedal stack. I prefer to keep at least a 5mm spacer under a stem for these reasons.
The seatpost is not set at its final height in these photos.

Nice to hear that you like the paint.

Cool bike- What fork did you use?
Is there a nice road fork out there that allows for a tire in the 33-35mm range?

My regular painter took care of this as usual. He has to tape up plastic sheeting to catch the paint that misses the frame to keep his work space clean.

The new ENVE road disc fork has clearance for a 32, then their GRD version can take 38mm.
This fork is a special weight weenie unit that I source from the manufacturer - 350g. But it can only take a 28mm tyre, maybe a 30.

The super-duty sprinter edition tube set. The joints have been wrapped with prepreg carbon which will be cured in the oven.
