Is it just me or is trying to adjust your brakes on a moving bike a silly thing to do
I've done it often. Stopping to deal with bike problems is annoying if it can be bodged on the move. That said, I wouldn't do it when wearing fingerless mitts but would with full gloves, I'd keep well away from the spokes and even then it's a good idea to be very wary because the smallest bump will mean your glove is scuffing the tyre.
It's harder to fiddle with the brakes on a road bike than most bikes because the brakes are smaller and so are the adjusters, but a small-wheel folder or front-loading cargo bike would be worse! In a neutralised zone, I'd stop. Too much pain risk for too little gain.
