Yesterday after work (Of course I stayed 'til 5:00 even though all my coworkers were gone by 2:45. Honest I did. Why do you ask?) I made another trip to Greensboro for another chain. This time I went to REI, which is similar to EMS, but not quite as good. I used to love going to the EMS store in Peterbourough, NH. I could spend hours and way too much money in that store.
But, back to the chain. They only had one ten speed chain. A Shimano 105 for $42. I bought it, brought it home and installed it. Today, I went for a ride. Well, a 100k (63.22 miles and averaged 17.1 mph) ride for the second Saturday in a row. Perfect shifts throughout. No problems whatsoever. So it really was the Wipperman chain causing all the problems. If you get a chance to buy one, DON'T.
Last September I rode one time for 29.7 miles. That was mostly because of problems with my asthma. There is something out there in September that really affects my allergies and my breathing. I had some of the same problems today, but, I have ridden four times for 124.49 miles already this month, and don't plan on stopping unless my breathing gets much worse.
