Riding with broken spoke

yes, could have carried on

the more you ride with a broken spoke, the more stress on the rest of them and the chance they too might break

i've raced 25miles with 2 broken spokes in the past (wheel trued ok after).
i've also ridden 20 miles on a flat tub (rim needed filing down a bit after but wheel ok)

I would urge real caution, particularly if the spoke was in the front wheel as any sudden decelerations due to front wheel lock due to the spoke coming loose and fouling in the brake bridge can be either very comical or very painful!

If I was close to home I would cable tie a broken spoke up and return home whilst taking it easy...if I was out on a longer ride then I would stop, remove the tyre/tube and see if the spoke could be completely removed from the wheel before proceeding.

Low spoke count wheels will start to go out of true fairly quickly after a spoke break. I was riding in a group where someone broke a spoke a few weeks ago and the wheel was so bad that the wheel had rotation issues even with the brakes completely backed off. The wheel was clearly rubbing on the carbon forks which were beginning to show signs of wear, not good!
