Studded Tires and Power Output

Well I rode with Kevin Young this morning w/ the studded snows.  I took the inside the whole time and had no problem with the ice.  Very reassuring.  The only problem was that my average power was 200 watts and Kevin's was 150, despite his being being 8% heavier than me. Good thing I was looking to do some work and he was on a recovery day.  I do recommend them for solo rides early with frozen snow run-off.  For non-solo rides, you're going to do a lot more work.  All in all somewhere between a novelty item and a nice extra for a spare set of wheels. You'll need a 'cross bike for them.
