new frames. BRBR www.torelli.com www.gunnarbikes.com www.waterfordbikes.com www.nobilettecysles.com www.calfeedesign.com All have offerings in your price 'range'...

On my 23 mm tires I usually run between 100 - 130 psi depending on the road. 110 psi is pretty much standard issue on the roads around where I live. Do you notice a difference between 110-130 on the same bike/tires? --TP |

In article , says... OK, here is the story. I am fairly new to road biking but have fallen in love with the sport after making the transition from mtb. I currently own an dura ace/ultrega mix Cannondale 2.8 and am looking to upgrade the frame to somethng a bit more compliant. A frame upgrade is not going to make the ride more compliant. Try fatter tires are a lower pressure. ------------- Correct. A downgrade, however, will. Borrow someone's old bridgestone R-B and find out. -dkl |

Try fatter tires are a lower pressure. I absolutely disagree on that. I did a test ride on a Trek 2300 ( Alu ) and a Trek 5200 ( Carbon). Both have the identical geometry according to Trek and they were the same size frames. The difference in feel, comfort and handling was significant. Question, were the tires, and more importantly, tire pressures the same? I have three steel roadbikes, and they have three different feels. I have run relatively few (3 or 4) different tires, always 23 or 25, always at 115 or 120 except for the occaisional day at 110. I think that the difference in the way that the bikes themselves feel is more significant than the differences in feel due to the tires, as long as they are 23 or 25 and 115-120psi. I think there's a lot of oversimplification going on here. In the world of dirtbike suspensions, they talk of low- and high-speed damping. Low speed hits are jump landings. High speed hits are logs, ledges, rocks, etc. I suspect that tire and PSI choice might affect the ride after high-speed hits like cracks in pavement much more than than they affect the ride after low speed forces like cornering. I have read the argument here that all frames are very stiff vertically, and there is essentially no vertical flex to be gained by choice of frame material, and I accept it. The difference, I suspect, is largely in the fork. I also suspect that whatever people mean by "compliant" is more affected by what a material does after it takes a hit, rather than any difference in vertical stiffness. dkl |

From: "Per Elmsäter"
(I asked): Do you notice a difference between 110-130 on the same bike/tires? (PE responded): Do you? I've never used 130lbs. pressure on the road, except on a wheel borrowed in a race. The ride seems to get harsher around 120lbs, so if the 23's weren't enough tire to prevent "pinch" flats, I'd go to a bigger tire, as I did when riding dirt roads regularly in the past. --TP |
