I have a Cannondale 3.0 that has been ridden. I put at least 10,000 miles on it. It has dura-ace components. I can't face the thought of getting back on this bike after riding less rigid bikes for a while, so it hangs in my basement with spiders living in the wheels. I don't really want to go to the trouble of selling it, so I am thinking of donating it. Are there any charities that are capable of dealing with a bike like this?

I donated a couple of desirable vintage bikes to a local bike charity, thinking they could make money selling them on line. They didn't want to be bothered, apparently. They were gathering dust, just in a different place. It's pretty easy to sell bikes locally on CL if you just want them to go to a new home. Set a price low enough to be attractive but not so low as to bring in the flippers. It feels good to know you've given someone more than their money's worth. Lagniappe.

In my area, bikes sell better on Facebook marketplace , CL is pretty much dead around here.

Bike co-op or bike collective. Whatever they are called near you. Nonprofits that do various good things with older bikes, depending on location.

Pittsburgh has a few for sure.

I donated a number of semi-desirable bikes to a local charity who serves the refugee community. They appreciated that the bikes were a step up in quality from the department store offerings. Like you, I didn't want to bare the hassle of haggling price over a bike for which I had a sentimental attachment.
