I bought my K with a 70t chainring. 70 is a big number, so big, that I even at 65kph, my cadence would be only just over 90rpm. Indeed, that makes no sense. With 61t, starting is easier, and the whole range would be more 'close ratio'. Velomobiel.nl had a 61 in stock and I rode there to get it.
I left at a quarter past 10, and grabbed a banana after 45km, that I ate whilst riding. A short pause after 58km for the pond across a water. 42 km later I was at my destination.
There was quite a crowd at vm.nl. Velonauts for parts, advice, technical problems, new vm's or just out as a group. Nina had brought something tasty to share. Marjolein's Strada had a small technical issue with an own will. I quickly received my 61. When asked how I'd install the new part, I simply replied: 'just crawl in'. And once I was in, swapping the parts was easy. Most important, I didn't get stuck on my way out. Than there was more time for eating and some velo talk. Clement found out he fit's in my K. Others studied it, up close.
Back in my Ksynonica J. for the ride home, I felt at home again. The 9t less on the chain ring make it a lot better to ride, much easier and smoother to accelerate. The evening before, I'd swapped the hard chain tube for a softer one, with flared ends. That lowered the sound level a lot. Velomobiles and hard chain tubes are not a good combination.
I rode the final 55km in the dark. A clear sky, a long smooth cycle path ahead and 36kph on the cyclometer. The Philips head light (tweaked to work on the onboard battery) gives a nice beam, wide and far. And when 20Lux isn't enough because of dirt on the road, the high mode of 80Lux certainly will give enough light. Day's total was 180km.
