Road in today using only two gears 'cause the rear derallieur stuffed and I didn't want to risk snapping the cable.
What a beaut ride! OK the weather helped, nice and brisk, but it's the fastest I've ever done that commute. My rear's stuck in the 3rd from highest gear and I spent most of the time in the bottom ring. Unfortunately I start to bounce at a cadence of 125 which is the only reason I stepped up to the big ring, bit like an overdrive. It was a very different riding experience as my cadence was as low as 75 at times. Im used to keeping it between 95-100.
I doubt I'd last long doing that sort of effort every day but maybe I should stop being such a lazy bum and get my heart rate over 130 every now and again :-)
