Re. dress code for work, it's business casual in my office. Executive level staff have to dress nicer. Our CEO wears suit & tie every day, no matter what. He demands the same for those who meet with him.
So for me, it's usually dress or khaki slacks and a golf shirt.
This summer, I realized short sleeved button up shirts are better on a bike; they allow all kinds of ventilation options. If it's cooler, tuck in and button all the way up. If it's hotter, undo the top two buttons, untuck and undo every other button for a lot of flow-through.
We're allowed to wear jeans the last Friday of every month. Sometimes, I push it and wear jeans-style pants, that are not denim and not blue, and that seems to go over OK.

Tom, hauling a bike up 4 floors' worth of stairs every day is sure a workout! The school really doesn't have anywhere semi-secure for staff to lock up their bikes at ground level?!

1st ride back on the Aventon Level.2 commuter eBike this morning after a few weeks of it being down. I did my first chain change on it. On the first try, I bought a too-short chain; didn't notice the spec. Used my quick link pliers for the first time. Sprockets were OK. Shifting is still iffy during the upshift from 6→7. (of 8) I crashed the bike twice though, and at least one of those times, the derailleur took a good hit. I wonder if the derailleur hanger is bent. Need to look again. I think Aventon included a spare. I have been commuting on the 15 lb. lighter Tern Vektron S10 while the Level.2 was awaiting its chain. The Level.2 is a lot more work to get going from a stop, unpowered, but it sure rolls nicely and is nice & powerful when I want it. (500 W motor, peaks at 750) I'm going to take this more often on the no-drop group rides where I get someone riding off the front pretending they didn't notice they dropped a bunch of people. ;-) I used some Boeshield T-9 the first time to lube the chain, cables and derailleur pivot points. I put some in some of the fasteners that have started to rust from a couple winters' worth of commuting in the salt. It is a really thin oil, allegedly designed for aerospace, that has some really hard wax when it dries. We'll see how she does!

(Aventon Level.2s are now on finally blow-out for $700 less than I paid for mine. Great bike. No affiliation.)
I wore a windbreaker this morning for the first time. It felt good. Work gloves will come out tomorrow. I slowly acclimate to the weather and it's rare that I feel cold. I think there's the issues of age, circulation, normal body temperature AND fat insulation that all play their parts. I have a low normal body temperature around 97 °F and probably 20 lbs. of excess fat around my torso. (5'9, 166#) But good circulation too, so I just have to take care of my fingers and toes and I'm good. I remember being a kid and wearing a hoody and jean jacket all winter, and winters were COLD back then. I was only ever cold while stationary waiting for the bus.
