Lucky you!

My bike sits on concrete when home here, so the tires & air inside can cool quite a bit. After a ride on a hot day, this can create a bit of slack, that in turn makes for a very sluggish ride... So, i'm pumping up 50% of the time due to temperature fluctuation after the bike sits for hours in a cool garage on cold concrete.
