If they do you are using the O-ring for 31.8mm bar diameter with a 22.2mm or 24mm handlebar. And why a flashlight? Flashlights are for hands. I get that flashlight makers won't mind if you buy a lock-block and use a flashlight on your handlebars and if you already have a flashlight you like and want to get a lock-block, who am I. But, if you don't have a flashlight and your need is for a bike light?? I just don't get it, why are flashlights recommended 2:1 vs bike specific lights whenever this topic comes up? While I am stirring the pot... dare I ask... what is the cheapest Hub/Light combination that is available? Would someone considering <$20 lights be a good candidate for even the cheapest of dynamo lighting? FWIW Performance Bike aka Bike Nashbar sell a front/rear light set marketed to commuters by Ascent ~$14. The front light is prolly 1/2 watt, big lens though, lots of light. Some people use them as to see lights, God Bless Them. The rear flasher is especially nice because it slides into its clip sideways. Most hits you take on a bike have a vertical component. Conventional flashers pop right out and you never see them again. The Ascent rear flashers stay put through anything that will not also trash your rear wheel. I have two sets of these. No longer use them. I only ever ran the headlights in flash mode as a be seen always on back-up to my main light which ran only in the darker sections. I could give either set away for the postage.
