Another way of looking at is that you can go faster with the same amount of effort. Either less effort to maintain a given speed or more speed for the same effort can be a real advantage to acommuting bicyclist who has a long commute. I think that there are a lot of people who commute on racing-style bicycles because they enjoy the ease of getting up to their cruising speed and the ease of maintaining that speed compared to a heavy bike. Also, a lot of people use their commute rides for training or improving the person's fitness level. When I lived in Toronto I used to do a lot of interval training on my commutes. Sprinting from one stop light to the next was great fun as was seeing just how short a time I could get my commute down to. Different bikes and or wheels for different folks. Sounds spot on and very familiar to me. And here too. -- JS |

Not saying that light wheels necessarily lack reliability, but there is that issue. I sagged our club's century about a week ago. One of the guys I helped was on a nice CF bike I'd never heard of - some small manufacturer in Massachusetts, I think he said. Anyway, he didn't carry a pump, and he was out of CO2 cartridges because of a puncture, followed soon after by a blowout. I found the chip of glass he missed, so he decided to patch his tube. I pumped his tire, we put it in the frame, and I noticed the brake scraping at one point. Turns out the rim's sidewall was bulging out. At that point, I didn't know if he might have hit a pothole that he didn't mention or what, but the bulge in the rim was almost certainly responsible for the blowout, and it wouldn't make sense to try riding it that way. I asked him if he wanted me to try to squeeze the rim inward so he could ride back to his car (not far away at that point). He said yes, so I got my Channel Locks plus some stuff to protect his rim, and I was astonished at how easy it was to squeeze the rim back in. It certainly looked like the brake shoes had ground away enough rim to put it right on the edge of failure. Sorry, I didn't note the brand of rim. I could describe it if anyone's curious and non-snarky. I've ground down rims -- even pretty stout rims like Mod 51 and MA2s, although not to the point of failure. My usual bit of stupidity is wearing tires to the cord without noticing -- until I start flatting in the middle of nowhere. My Mavic OpenPro Ceramic front wheel is still going. I was trying to determine just how old it is. I think about 12 years. I use it pretty much exclusively. Judging by that, it's seen about 120,000km of action, and the brake surface doesn't look more than a day old. It's not *stupid* light, but... -- JS. |

Upgraded Wheels Benefits
I've not ridden one...only one aluminum, breifly...I was impressed.
Point there...get the potential buyer zaaaaaap once and sell. Before he ralizes itsnot really THAT FASTER... or izzit ? we read 1 pound less equals 5 extra collonade/acre/ergs over 10 miles and everyone goes ahhhhhhhoutsite Ima gonnna runout and buy one. but never tried it over the 75 mile course run here in the flatwoods. but if you don't ....like coke or sex with heidi klum then you don;t know tree falls in the woods so what ? taking an opposing position... |

I think a lot of the upgrade benefit depends on what you're upgrading from, and what you're upgrading to. And, since this discussion group is labeled "tech," I'll mention that a lot of the benefits are reasonably quantifiable. IOW, we can work out reasonably accurately how much extra acceleration you'd really get, how much more speed for the same effort you'd get, how much faster your commute would be, etc. The physics of the bike have been worked out for at least 100 years; it's not rocket science. Websites like Damon Rinard's (who is a respected professional in the bike industry) make many of those calculations pretty easy and automatic. And although it can be fun to ride a bike that feels... And there it is. You've said it. Absolutely right. ... snappier, it's hard to pretend that the performance gains really amount to anything practical, at least for a typical commute. Does it occur to you that a rider having fun may perform better? Of course. I've talked before about the psychological effects of changes to the bike. And what's a "typical commute"? (I asked nicely.) It's 7.2 miles. Almost exactly the same as what mine was, it turns out. Mine was 6.9 miles by one favorite route, about 7.5 by another, and I always kept it under 30 minutes riding home. (Home was uphill.) From A SURVEY OF NORTH AMERICAN BICYCLE COMMUTERS By William E. Moritz, Ph.D. available at http://www.bicyclinglife.com/Library/Moritz1.htm "COMMUTE DISTANCE / TIME Usual Bike Usual Bike Distance Distance Time Time Average 7.3 mi 7.2 mi 20.4 min 30.3 min Median 6 6 20 25" I actually like your whole post here quite a bit, but I notice that you seem very focused on measured data, which can really get in the way of fun. Well, it is a "tech" discussion group. -- - Frank Krygowski |

My SL bike is my version of a sports car and my Sport-Touring bike is my version of a heavy duty pickup truck. I have to point out what a laughable standard that is for "heavy-duty pickup". Sounds more like a sports car that has a small trunk versus one that doesn't even offer that much. I have a flat bed sidecar bike that has toted six adults in the past, and now sports two sturdy chairs on the load bed. I have a 2.5' x 6' cycle trailer that my wife used to carry home our washing machine, and which I use regularly to carry up to about 400 lbs of groceries, laundry and what have you. When my wife goes to gigs within a few miles, she loads up one or the other of these machines with her 50" wide keyboard in its case, a keyboard stand, an accordion, a ukulele, PA speakers, a couple of mic stands, an overnight bag full of cords and stuff, and a hat box full of merchandise. Try that with your so- called "heavy duty pickup", why don't you? These are not one-off stunts; they are just examples of what you can do with a bicycle if you don't have a ridiculously myopic notion of what constitutes "heavy duty". Actually doing useful things with your bike is way more gratifying and can be more fun than just adding 2mph to the speed you'd be riding on a versatile, practical, durable bike. Chalo |
