It's meant for a 53/39 chainset not the smaller rings you have. You would ha e to do so.e filling on the braze on mount to rectify or get a standard double.
I like that phrase a standard double. Of course it's no longer the standard.
So tempting but I'm poor.
25mm to 40mm is sensible.
Internal width x 1.3 to 2 is a good guide to tyre real widths for road tyres.
With stiffer sidewalls you can go wider still.
So 32mm is the bare min width for 25mm internal width tyre but I suspect it will look stretched. 25mm in a 19mm internal width rim seems less stretched but that also depends on the tyre.
Bead to bead distance and the thread thickness across the tyre are important factors. Hense guidance at the extremes is always vague.
Yet trek are fitting 32mm contis to such rims for a madone. A tyre stretched like that will wear like its under inflated due to it shape.
I have had a similar problem with a 25mm conti gp5000tl tyre on a velocity aileron rim. Thats 20mm inernal width and it proved to wide with tyre wearing like its under inflated. Less of an issue on kinlin rims. Tyres are made with certain range internal widths in mind.
I have a 58cm boeris track bike.
With IRC tyres because they are generally smaller for ther size than others apply enough tape so the tyre for is tight. Then with soapy water they inflate easily.
Bigger tyres tend to I flare without needing to be as tight a fit. IRC tokens can inflate while being an easy hand fit.
I'll take it. Where are you
Extension rebellion sounds too.mich like an apocalyptic cult is you read some.of what the groups writes.
I saw on the groups logos.on a VW 70s camper van
Very petrol powered and inefficient. It's that kind of irony that makes folk think the group is not shall we say in the real world. I woder how many of the groups supporter drop e to work this morning or where driven. I ride daily. That does not make me a saint but encouraging that instead of apocalyptic doom and gloom will have more success in the long run.
The groups leader needs to u understand making the group sound like your preppers marginalised it. Yes preppers
They prepare for impending global doom. I see no difference between he physiology of preppers and and exction rebellion activists. There always an apocalypse to prepare for. It practically religious. Christianity has the apocalypse to prepare for by doing gods work so your soul is saved or that's one interpretation of the more fundamentalist strand of the religion. Same thinking. It turns most folk off.
Spokecalc is the most versatile spoke calculator as it alow fractional crossing. The dt swiss calculator is great for straight pull hubs.
I need to create a sheet for spoke calc so it can handle straight pull spokes.
I have worked it out. Use spoke calc and enter 2.5 or 3.5 cross and add the spoke hole offset from centreline. That not easily measured and varies between hubs
The welsh 12hr has a road bike category. Might have to do that and 24hr. The breckland 100 mile course uses much of the 12hr tt a11 route but not all of the off a11 bits.
I'd just like to reach 240 miles in a 12hr on a road bike and 400 for a 24hr. Got to stop going to sleep though.
