Hello guys,
I just noticed one rear wheel spoke broke! I have 17" wheels from a Moulton F-Frame
i commute to work on my bike, is it safe to continue with one broken spoke? ive seen many wheels with less than 28 spokes working...
the rear wheel is 17" with Sturmey archer 4 speed, i measured the spoke and its exactly 6" long from the hub to the middle of the rim nipple.
tried using a calculator but got stuck on the rim size

i wanna order replacements ASAP
also im lurking ebay for a sturmey archer dynohub, but wonder what size spokes i need since dynohubs use 2 different spoke lengths
