Re: [RBW] Some comparative biking data
How did you determine the speed figures to compare? Average over same route over many laps? I find that my 17.75 lb Riv Custom Fixie Fastie is certainly faster up hills with its 75 gear than my circa 22 lb Riv Custom Fixie Commuter (largely identical in build except for fenders, Tubus Fly, SON + lights, heavier pedals) with its 69 gear, tho' truth to tell I am also usually carrying at least a small load on the Commuter. And the Commuter is faster than my 67 gear and much heavier (tho' frame is lighter) and much heavier wheeled '73 Motobecane Grand Record fixie grocery bike; again, taking hills into account. On the flats there is probably not that much difference as long as there is not a great deal of stopping and starting.

The Nashbar is probably the fastest if all the miles were on the same course. I practice hills on it because I really like its mustache bars for climbing. It was originally designed along the lines of a crit racer, iirc. It's not my favorite for anything over 30 miles, as the position is a bit aggressive. The Riv road is what I prefer on medium to long rides at speed, and the Saluki for loaded longer hauls, or very steep grades with the 26 low ring that its prior owner thoughtfully provided. So how come the fastest bike and the one with the most miles over the years is the Ram? Because it's just about as perfect a fit as I can imagine and handles really well. And its easy on the eyes as well. -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

Re: [RBW] Some comparative biking data
Patrick: I looked at the data for all rides this year. It's not scientific at all, as the average climb per mile varies a little between the bikes as does the average length of ride. Even all the tires are different. All have about 600 miles, and I guess my point is that it has more to do with the rider, than the ride. Tailwinds..

Re: [RBW] Some comparative biking data
Thanks; makes sense: not scientific but usefully anecdotal. Regarding Charlie's remark about position being a factor in speed: I find very clearly that when my bars are too high, or when I am riding on the flats, say, I generate less power. This may well be a purely individual idiosyncrasy, of course. Riding fixed as I do, I will routinely drop into the hooks when I round a bend into even a moderate headwind and, even, when I encounter a gradual incline: a lower position seems to give more power as well as doubtless being more aerodynamically efficient. Of course, on steep climbs I ride on the flats but shove myself way back on the saddle.
