    SJS has Alpina spokes

    Only in gross boxes, AFAIK. Cyclebasket is the usual source for ACI/Alpina spokes.

    Based on what my 25C GP4000s measure on similar width rims (nearly 27mm), I'd guess that the 23C comes in somewhere between 24 and 25mm

    I'm surprised that bicycle builders allow themselves to be led astray like that, maybe they have no knowledge of motorcycle history. What we have there is basically a Hossack front end

    Many have tried (Bimota, Hossack, BMW, Elf and doubtless dozens who didn't even get that far) to solve the "problem" of telescopic forks, which is that braking compresses the suspension and changes the steering geometry. What pretty much everybody has eventually discovered is that the cure is worse than the disease, mostly because the disease turns out to be a feature, not a bug; a bit of brake dive which stiffens up the front suspension and quickens the steering is almost exactly what you want given that the front tyre is loaded up.

    23mm though

    23C tyres on 23mm wide rims are better than 25C tyres on 20mm wide rims, and GP4000s come up a bit bigger than nominal even on skinny rims, on 23mm rims they'll probably be nearly 25mm across anyway.

    She kept running 'out' instead of 'along'

    Maybe she wanted a cuddle

    Can't really think of a reason to spend more money on fewer?

    The double crank has a smaller Q?

    what is the best way to get a clean vertically straight cut for the slot in the top?

    Router. And, as ever, fixturing is 99% of the job. Once you have the workpiece and the tooling securely in the correct alignment, everything becomes simple.

    At 63kg I am not much of a "natural descender" so not sure how much the gift hill will help

    About 60kJ, that's as much free energy as having 46W more power for 22 minutes

    Bowie is yellow, apparently

    So is Jaune Baez

    Is the reason for using the M525 step-down axle + SPNK M10 seats, a strength-related one

    No, it was just a suggestion based on its usually being easier to find M10x12mm bearing seats.

    I've tapped several 9mm axles and never had any issues, and I press down on the bike more than most people.
