    softening the ride of a cannondale 2.8

    Hi --

    I "inherited" a 1994 cannondale r2000 frame. After searching old BF threads, a lot of people have noted how stiff and bone rattling this ride can be.

    I am really digging the lightness of the frame. So, out of curiosity, if I change out its fork and opt for using a carbon fork...how much will this do towards softening its ride?

    If there's more that I can do...please advice.

    Thanks in advance for your help.

    Just get 28mm tires and use moderate pressure.

    If you're building a frame from scratch, it would seem a carbon bar had more flexure than the fork would, although I have never tried a carbon bar.

    Yeah, I think fatter tires will have an order of magnitude more effect on the ride than anything else (including carbon bits).

    Most people can't tell the difference between a steel or carbon fork.

    I'll agree with the 28mm tires. I've got an 1986 C'Dale SR400 and the ride is, well a bit harsh. On the bright side, it's stiffer than an I beam and light and climbs great. Mounted these up on both this bike and my wife's CAAD 5. you may also look into some non-aero rimmed wheels. These can be a teeny bit softer that the deeper profile wind cheaters.

    I have a hybrid and I took a more drastic approach that was almost excessive. I mean I put on 700x45 Kenda Keen Commuter tires (which I found out was way, way too much, could have settled for something from 37 to 42), a Velo Plush saddle with springs underneath and I already had a suspension seatpost. Now I can't feel a darn thing.

    Now, I almost can't wait to complete my touring bike because I'd like to know what it's like to feel SOMETHING rather than nothing.

    For 28mm tires to have any effect, you have to explore how low it is wise to go on the pressure. If you hit a sharp edged bump and the psi is too low you will get a flat by pinching the tube between the road and the rim through the tire sidewall. However, if you run 28s at the same psi as 23s, they will actually ride more harshly.

    +1 I have both types on my bikes and have concluded the fork has little to no effect on ride harshness. Softer Ride = Bigger, lower pressure tires.

    That's cool to know.

    Anything you do with the wheels and tyres will have more effect on the rear, since it takes 60% of the weight.

    A low profile rim on the rear makes sense, but since it makes less difference on the front and that's where an aero rim works best, I'd stick with an aero front if I had one. Likewise, if I was going as big as 28, I'd have a 25 on the front.

    Also, Canyon has a new carbon spring seatpost with 20mm of travel. It's pretty slick.

    To the OP:
    Set your tire pressure according to this: http://www.dorkypantsr.us/bike-tire-...alculator.html

    Don't Cannondales have an aluminum fork?

    I don't believe that people can feel the difference between a stiff wheel and a flexible wheel. When they claim they can, it's the placebo effect combined with expectations. A ton of folklore goes through the cycling world.

    The advice to get wider tires is sensible and effective and economical.

    I'm pretty sure a deep 700g rim would feel harder than a 380g box section rim, but you may well have a point there... it prolly doesn't add up to much.

    In 1994 all but the Track and Touring frames had aluminum forks.

    Earlier years they had CrMo forks on all models.

    smithms2, I've rode Cannondales for a couple of decades, tire pressure and or larger tires help quite a bit in taming a stiff racing frame (of any material). The frames were hand made so it is possible yours will fit a 28C, but I think it's unlikely. I weigh close to 190 lbs. and I generally run 100 PSI in my 23C tires and have run 85 PSI in the 25C tires.

    Between the steel, aluminum and carbon forks there was very little difference.

    I had a long reply then hit back in my browser.

    T400 - Schwalbe marathon 32's @ ~80psi - cro-mo fork
    - this bike feels so much more stable with a load on it. I am guessing my tire pressures will be good once I go on tour, but for commuting to work and back its fairly harsh, the extra weight will help calm that puppy down.
    R500 - Panracer Pasella's 28 @~100psi - aluminum fork
    - fast, light, and suprisingly plusher than the marathons

    Overall, if you want comfort, tires are THE deciding factor. all these super stiff parts of the bike aren't going to give you any type of suspension.

    wht kind of wheels do you have? if your wheels are those deep V section type ditch them for some 36h 3 cross box section wheels. they are a bit heavier but will ride better esp with x28 tires.

    you could always go steel too

    krailzec, I run 60 PSI in the 35 mm tires on my T700 when unladen. Up to 80 PSI when loaded.

    First, folks above dispute the rim is much of a factor, and second, box-section rims are often significantly lighter than deep rims. Box-section rims can easily be found as light as 380g, whereas a Velocity Deep V weighs 518g. This is typical.
