Front Hub Question Raleigh Twenty

HI, returning to the forum after a bit of time away. I recently picked up a 1974 Raleigh Twenty on craigslist. A bit worn but I have always wanted one - compliments my 1973 Raleigh Competition (I have had since new!).

I need help with determining spoke length for a front wheel build. I have never attempted a wheel build and thought this would be a good chance as any to give it a go. My problem is I can't find the regular sturmey archer front hub (non drum brake model) in any of the on line spoke calculators. I bought a nice set of Sun Rhyno Lite 406 chrome rims to keep the look going (wider than the CR18 too). My local bike shop always seems too busy to help me out on this (even though I bought my parts from them).

Does anyone have the dimensions for these hubs? Am I missing something obvious? Seems odd that the spoke calculators have the three speed hubs but nothing for the front wheel.

Greatly appreciate any advice or help you all can share. In the meantime I guess I will start with the rear wheel!

David

Are the new rims all that different from the originals? If not, measure one of the old spokes and use the same length.

Not sure how much difference there are between the original steel rims and these Suns. May just have to break down and start trying to measure!

I'd do a shout out to @Velocivixen, who could answer your spoke length question in seconds, but the mention function is broken right now.

@gugie - Unfortunately I do not know, precisely in practice how to measure. When I took my 3-day class at Sugar Wheel Works, the goal was to teach us how to build 2 wheels. So we spent time on some theory, lacing, truing, tensioning, etc.

The spoke length calculations were more of something she mentioned at the end. I take my hub and rim to their shop and they measure, cut and thread my spokes. One side vs the other usually has variance of a mm or a few. Sorry I can’t help.

I do think Rhyno Lites are great rims for a substitute on these bikes. Even on a standard sized Raleigh.
