According to Sheldon's gear calculator for yesterday and today at my top speeds of 25km/h on 40/23 my cadence would have been about 110 and 27km/h on 40/21 my cadence would have been around the same. I find over 100rpm is a bit too high for me, but as I said my knee has been fine yesterday and today.
OK I am sticking with the cadence theory. 110 is highish but not OTT by any means. I aim for about 102 or a bit higher on the flat, plenty of other experienced cyclists also aim for that kind of rate, some aim higher and plenty also aim a bit lower (there is a element of personal choice rather than a perfect cadence that we all should aim for). The fundamental issue though is the spin, and it sounds like you are reaping the benefit of spinning a bit more than you ususlly do. Experiment a bit but try to keep it highish you'll get used to it and the ongoing benefits (to your knees, your speed and your endurance) may surprise you
PS...you don't need a computer with cadence: just use the stop watch/timer function and count your reloutions for 10 seconds then multiply by 6...(ie 17 revs = 102, 18 revs = 108 etc)
Ok, so I am learning how to ride a bike. I went for a 30km ride after work today and found that pedalling too fast just puffed me out and pedalling too hard made my knee hurt... somewhere in between though is a spot where I was just lightly pushing down on the pedals, but still maintaining my speed (the sweet spot?). For me, pedalling too fast is just inefficent with my bike bouncing up and down... a waste of energy. Riding in the sweet spot is much more energy efficent for me. I just finished a 30km ride and felt the same as when I get home from work after a 9km ride. I could have kept going but I got hungry. BTW I don't think that my knee is sore from poor riding, it most likely sore because I have gone from being a complete couch potato to riding over 600km since the 23/2/2009. I am glad my knee is sore anyway because it reminds me when I am not riding in the sweet spot. Riding in a single gear all the way to work and back is making the ride more interesting too.
