I have been pedalling on the small chainring. I idea is to pedal faster with less effort, with an average cadence between 90-100 rpm.
This past week, maybe longer, I have noticed an annoying chatter when I’m pedalling in some gears. So annoying that I would change into a larger or smaller one just to quiet it down. It kept getting worse despite my attempts to adjust the cable tensions, or the position of the front changer.
Today I had had enough. I rode on the large chainring. There is no chatter there.
I was once told that pedalling on the large ring develops strength. I was climbing up one of the local mountains, when I came along side a young rider turning a big gear. He said he did this climb once every week or two pedalling in the largest gear he could. It developed power he said.
Well today was supposed to be a slow day. A recovery day. A Zone 1 day. I did 48 km on the large chainring averaging 25 kph but with a slower cadence. Eighty-one. So, I was turning a larger gear but spinning about 10 rpm slower on average. Did I feel more tired? No. It was all in Zone 1, at a lower heart rate. Did I travel faster faster? No. The same as I do in a lower gear but at a faster cadence. Did I develop more power by doing this? I don’t know. But it certainly felt comfortable, and easy. Maybe I am getting stronger.
I’ll stay on the large chainring until I can figure out the cause of the chatter. At first, I thought it was the BB but I have now isolated the problem to the small chainring. Maybe it is loose.
