I took up riding this summer and have been making good progress. Last week I started to get sore knees. I ride 25 mile loops two to three times a week. So my research lead to too slow cadence. So I ordered a pair of A530 and RT51 for this weekend. Went out for my two loops and no sore knees. I found that that I could increase the cadence dramatically since I could keep the feet attached to the pedals.
Final benefit, I increased my average MPH from 12.4 to 13.9 today. Goal is 15.0 before the summer is out.
PS: I ride a Menona Hybrid for now. Maybe a road bike is in the winds for next spring. And yes I will admit to one fall. Got too cocky the first time out. Now I unclip at each cross street.
