    how to make my aluminum bike less bumpy

    I have a Bianchi built with Easton Elite aluminum tubing. It has a rigid fork, I like that, kind of old school.
    Other components are also aluminum, like stem, bar, seatpost, nothing exotic. running street tires, and
    some older matrix/mavic rims.
    However it is very bumpy, vibrations just transmit straight up to my spline. I have ridden stiff
    road bike like old school Klein Quantum, but this Bianchi is more bouncy than the Klein.
    I am just talking about flat road with less than ideal surface, not dirt road or trail.

    I have a carbon bar coming, but I try to stay away from carbon seatpost...

    Any remedies??

    IMO, there is either something with your wheels or you are just a wimp (not trying to offend you or anything, but...). I used to have a full rigid that I did real mtbing with. I just used the biggest tires I could find and ran them as low as I could.

    Edit: You might want to try a new fork. You might just have a really stiff fork.

    Bigger tires, lower psi, tubeless if you can (allows really low psi).

    You could run your spoke tension on the low end and or get a cushy seatpost. I have a Kent Eriksen titanium layback post that is very comfy.

    I really want to continue to use my 1.25 street tires. My bike takes a 26.8mm seatpost, hard to find a size from carbon or Ti. What size is more popular with carbon or Ti, I could get a shim.

    Carbon or ti will get you negligible results in the bump transmission department, IMO.

    Take 5 psi out of your tires, and if that doesn't work, take 5 more out. If you have disc mounts on your frame/fork, consider switching to BB7 brakes on road wheels. You can run proper road tires, and the wheels will have a wee bit more give to them.

    Don't ride a rigid.
