Got my bike back yesterday after having foam (airless) tubes fitted - had a puncture last week, so this morning was the inaugural foam ride...

hello roll-resistance. It's like all my gears got bumped down one. Ah well, the legs were getting too used to the ride anyway.
Good ride, although I'm thinking of waking 5 minutes earlier so I can still see the sun rise on my way in. Gotta keep ahead of old Sol!
