This is a followup on my other post, "did a computrainer century yesterday".
That's a week old but I did a real century this week as described at the end of that post.
The purpose of this post is to talk gearing. I just installed a 10 speed Ultegra cassette and lever (removed a 9 speed Ultegra set up). The caviat is that, although I left the triple chainring on, the new front chainring lever is for a front double (which, since it matches the new 10 spd lever, I put it on and adjusted it for just the two largest front rings, ignoring the little 30t third sprocket).
SO, for yesterday's century I rode with the following gears.....front=52t, 42t and rear=12t thru 27t (10 spd). I DON'T CARE WHAT THE RACERS I TRAIN WITH SAY, I MISSED MY THIRD FRONT CHAINRING! I just don't understand why some say, "you don't need that granny gear". I ride with people that have $5000 bikes with double front rings. Are they so much more powerful than me that it's just not necessary?
There were times yesterday when, confronted with a 20 mph headwind, I was lumbering along at 7-10 mph in 1st gear (of my available 20) wishing I could spin just a little faster.
Needless to say, from now on, I'll reinstall my triple front lever and get back to a 30 speed, especially since I'll be pulling a Bob trailer for 800 miles!
OK, one more thing....re: the 10 spd rear cassette, when running along at 22-28 mph on those perfect surfaces (no wind, no steeps) I really noticed the ability to "fine tune" my cadence at a more surgical level than my old 9 speed (attributed to ONE tooth changes in the mid range instead of TWO tooth changes) resulting in a little faster for a little longer with a little less pain!
OK, that's my analysis, love to hear agreement or disagreement! Doyle
