Gidday folks!
I live in the Lower Mainland of British Columbia, Canada. My favourite training ride is a 20 kilometer loop from my house through the Derby Reach area next to the Fraser River towards Fort Langley and then back again. Not mountainous, but a helluva lot of (minor) uphills and downhills.... To me, a piece of level road is one where I did not shift for at least 2 minutes.
So out of sheer boredom and not to mention perversity I tried to count the number of shifts on my last ride (both front or rear counts as a gear change). I lost count after about 30 minutes riding at around 35 shifts. That's more than one shift per minute, and by implication an hour ride each day for 6 days a week equals 450 - 500 gear changes per month!
My bike is equipped with Shimano 105's and it has been performing flawlessly for the past 400 kilometers. No wonder a set of deraileurs / shift levers are rather costly items $$$ -wise (and I wonder how much better Ultegra or Dura-Ace, or the higher-priced Campy etc will perform). From my point of view, I reckon I am well getting my money's worth....
Some useless (personal) statistics as I said, but has anybody else ever thought about derailleurs in this way?
