My walking route to work is roughly a mile. Ordinarily, walking to work gives me two miles, round trip. But I got an unexpected call from the bike shop. When I got the new chain, they noticed the cap on the end of the left crank missing. I can't believe I never noticed that myself.
They had ordered a new one, and it had come in. I wasn't quite sure it was OK to ride, and besides I'm trying to get that irritation in my right groin to heal. So I walked the bike to the shop, about a mile from home. Lo and behold, the new cap was the wrong kind!
The guys say I should be OK for a bit without that cap, and the new part might even get in before the big ride on Saturday. I hope so! I don't want to have disaster strike in the middle of the century. Actually, the purpose of that cap is to be sure the crank arm fits snugly to the bottom bracket. I guess if it doesn't, the crank might get bent over time, or wiggle around under the stress of pedaling and cause biomechanical problems.
Being at the bike shop of course meant walking the bike back home. I didn't have my helmet with me, and I'm not about to climb aboard without it! Oh, well. I burned off an extra calorie or two, anyway.
