Fabulous commute today...bit of a rush going in as I had a meeting and only did my minimum 7 miles. I did 20 miles going home though and it felt like an early spring day. I actually didn't have to put on 4 layers. Managed to average 18mph for the 20 miles on my pannier equipped commuter (bike + racks + fenders + lights + water bottle and pump + panniers and contents = 51lbs.). Not a light bike by any means but I like it just the same...
