Liked:
-2006 Allez Expert (bought used this year), aka "The Mistress". My commutified CX bike looks, feels, and weighs like a tank in comparison (but still gets the bulk of commuting duties, as i *hate* riding with a backpack).
-Marathon Winter tires (great on ice, so-so on snow, but the routes I take get plowed pretty frequently).
-Axiom shoe covers. Keep the feet dry in the wet, and they're warm enough that I'm considering putting clipless pedals on the winter bike.
-Shimano internal-cam QR skewers to replace the stock external-cam units on the CX bike. Nice to have a front QR that actually *stays* closed and doesn't work loose (and yes, I do know how to use a QR properly).
2011 gear acquisition list:
-New bib shorts, before the old ones get me arrested.
-Upgrade CX bike disk brakes from BB5 to BB7 (or at least try a different disk design hopefully less prone to generating massive squealing when wet)
-New battery pack and charger for MagicShine headlight (but no rush, since the ones I have work perfectly, as they've done for over a year now

)
-Larger, waterproof panniers--as much as I've loved my Axiom Appalachians, after four years of hard use, they're starting to look like I've loved them to death.
