Re the calipers question last week...

I still need a 2-3 inch and a 25-50 mm and all metric above that.

A dedicated drawer for calipers 🤯

I've only got three.... so far.

I am proud to have an Amazon box with "various brake tools".

mad lad.

Using an IR camera on shiny metal to measure temperature 😶 that disk was probably way hotter

But a eddy current brake like on trucks would be cool for mountain descents

yep - a set-brake like a tandem can have.

AKA a drag brake

Indeed. Descending on a tandem just with rim brakes is... something 😅

He started with high chain tension and had to make it even more extreme because the magnets were still grabbing it.

I was glad when I saw her had real brakes on that (former) fixie

The 1040 is just out, and so we know that the 540 & 840 will be out in the next year or so. Adorama now lists the 540 (adorama.com/gp0100269500.html), but Garmin hasn't even announced it.
