Not just the occasional rain ride, but ongoing bona fide rainy, mucky weather. Where do you draw the line?

I get 18 months max out of wheels that I use regularly before I lose too much rim material for them to be safe.

Riding crappy wheels and tires is just less fun, and there's a lot to be said for riding what you love if you spend much time out there. With that in mind, I replaced the Forte Titans with some Rolf Aspins. Replacing those is going to sting later, but I'm thinking it might be worth it.
