I say put some studded tires on that Hardrock and keep on ridding.
I've got an old Rockhopper setup as my winter bike that I'll ride for the next four months.
I switched to it this morning and plan on going as long as possible. The last few years I don't think I missed more than a dozen days because of the weather[IMG]
