I’m tired. I could feel it last night, bad. That is, until I got back from my easy Thursday evening ride.
I just wasn’t feeling the love as I headed out. Five miles in and I stopped to help a couple stranded because they managed to drop their timing chain. I was unfamiliar with their type of eccentric bottom bracket that didn’t gave Allen wrench locking keys, it used a rather large nut (22-23 mm?) instead…. I simply didn’t have anything to get slack in the chain to set it back on the cog. Fortunately they had a ride coming to pick them up. How they dropped it is beyond me.
I got rolling again and I smiled at how good my feet felt. The new shoes are awesome. The toe box is a little bigger so my dogs have enough space…. The real test will come this weekend when I put some decent miles on them. The timing will be impeccable, but more on that later.
Getting back to my tired legs. I wish I could describe this more aptly, but I just don’t feel very powerful lately. I’m missing some liveliness that should be there. I know the answer, thankfully. I think a day off on Monday is in order. That, and another slow day today before we hammer out some good miles over the weekend.
I stopped at the shop to say hi to my friends before they rolled out for their ride, then headed home.
I pulled into my driveway expecting maybe a high fifteen, low sixteen mph average, based on how I felt and because my aim had been to ride slow anyway…. 17.8.
Maybe I’m not as tired as I thought. Sadly, I think I liked it better when everything made sense. Chuckle.
Fit Recovery 
I’ve been attending yoga regularly and it’s really helping with my hamstrings. They are super tight! I only ride 2-3 times a week though 15-20 miles a ride.
Older bottom brackets used to use a 24mm (or maybe 15/16″ aka 23.8mm but I’ve never been sure) nut and a C spanner for adjustment. Not seen an with that but it could exist.
…an eccentric…
Yes, an eccentric bottom bracket….
technical
(of a thing) not placed centrally or not having its axis or other part placed centrally.
In tandems, they use an eccentric bottom bracket for the timing chain. This way chain slack can be easily taken up, and so the chain can be removed.
It was a new tandem with old tech. Either way, whatever was going on, it was beyond my capability to do anything to help.
Yeah, I should have put “old-style” because I still see new bikes with 24mm nuts on the BB cup. I’ve just not seen an eccentric BB with it. Like you, I’d expect some sort of bolts.
