As set up for flat ground riding. Only using the middle and inside chairings. Current DS cog is an 18; flipped around so it lines up with the 42 middle, not the 46 outer. NDS is the 17-21 double. (This was for a ride with a 20 mile bike trail along a RR route. Bridge over a ravine was out so it was steep with switch backs on both sides.) 35 miles to and again from the path so it was a long day.
Triple - the three chainrings. (46, 42, 35) Fix-fix - a double sided track hug, fix gear with lockring on both sides. (The double cog is a regular 21 tooth cog flipped around and a 17 tooth with the center cut out so it slides over typical "bell" threaded part of the 21 tooth cog. Brazed on with a washer between, Used with a lockring as usual.
Edit: you can see the Pedros Trixie fix gear tool under the seatback, protruding forward. Good 15mm wrench plus an excellent lockring spanner that works far better than the usual plate steel shop wrenches on the bell shaped 12 tooth lockrings.

Nice bike, but my old body could not ride those bars.
That's a long drop, reach.
Good for you!
