Subject: my new summer wheel
|
I have a friction-powered headlight. Rather than ride another summer grinding energy for a headlight I don't use from about March to October, I bought myself another wheel. Nothing fancy, a Shimano 105 hub, some sort of ordinary Mavic rim. Wow. It's like another bike. I probably picked up at least 10% on my speed, I swear. And climbing hills is like a dream. A friend asked me, "does this mean you aren't going back to your friction hub headlight?" I replied that, since nearly all my October to March miles are in the dark, commuting, that I'd switch back without hesitation. I really do like the convenience of an always-available, never-have-to-recharge, can-never-overcharge light. But dang, I can't believe I rode for two summers with it. Yeah, on Thursday night I came back late, and I used just the cateye see-me light. But I'm usually never riding all that far under those circumstances (in these, less than 5 miles, in a street-lit urban environment), and it's well worth it not to have the drag. -- Warm Regards, Claire Petersky http://www.bicyclemeditations.org/ See the books I've set free at: http://bookcrossing.com/referral/Cpetersky

I don't think Claire has a Van der Graaf generator on her bike. Just an erstwhile hub generator that impinged a drag and weight penalty during daylight hours. Now she's got a lighter, free-er rolling front wheel and she detects a noteworthy difference. Same as switching to a pair of lighter tires. A Van der Graaf generator would be fun, though -- make yer hair stick up through yer helmet holes. cheers, Tom -- Nothing is safe from me. Above address is just a spam midden.

If you ever want that drag back for nostalgia, just do as I did -- buy a new set of wheels and then neglect to adjust your brakes before you take your first spin. Amazing how a gently-rubbing brake pad can make any day seem windy and any hill seem like the Koppenberg. (What can I say -- I wrench my own bike, so I've got a fool for a mechanic...) -JR

And with the money saved from not replacing them every year[1], I've already payed for my dynamo wheel + light. > But dang, I can't believe I rode for two summers with it.

I really should dig out my other front wheel. It's not so much the drag, but I could do with a little less weight. My bike is somewhat heavy admittedly... [1] Commuting year round in Seattle is not kind to anything except a *very* well sealed device. -- Dane Buson - sigdane@unixbigots.org For reasons beyond the comprehension of most people, many fixed-gear riders insist on riding with no brakes. They just fight the pedals and hope that their rear tire alone will stop them or that they can dodge. When informed of this bizarre cult, a friend of mine remarked that riding with deliberately ineffective braking offers all the exhilaration, sense of superiority, and irresponsibility of driving drunk without the hangover. I haven't thought of a good rebuttal yet. -- Carl Fogel in r.b.tech

If so, what kind of hub generator? I've got a Shimano 3N-71 hub generator powering my headlight, and it certainly doesn't cut my speed by any 10%. If your hub generator is a cheaper model, treat yourself to a higher quality generator hub like the 3N-71 or a SON (Schmidt Original Nabendynamo). Or have you just been riding around with your bottle generator engaged during daylight hours? :-D mark

At least, not for a stronger rider. I've never really noticed any extra effort. My average speed declines a little, but not enough for me too care much about. Especially in winter when I'm already riding slower because of poor light and extra wind drag from extra clothing. -- Dane Buson - sigdane@unixbigots.org A Dublin lawyer died in poverty and many barristers of the city subscribed to a fund for his funeral. The Lord Chief Justice of Orbury was asked to donate a shilling. "Only a shilling?" exclaimed the man. "Only a shilling to bury an attorney? Here's a guinea; go and bury twenty of them."
