Took delivery of a 105 chainset (now my drivetrain will match, hooray!) and a Garmin Edge 500. I'm justifying the spending to myself on the basis that the total's roughly the same as the credit balance I've just had back from the gas/electricity suppliers at my old house...
Also ordered a Topeak Tribag thingy to hold snacks on my bike in a place I can get to them easily. I like snacks.
