Today I received the improved version of the broken clamps!
Thanks to Mark Waters I was able to assemble them today and adjust my bottom bracket again. So tomorrow I will cycle again and from the day after tomorrow plenty of commuters!
Mark has made my worldview a little more positive. They still exist … people who help people without self-interest. My problem was insignificant compared to disasters that humankind is currently struggling with, but as a velomobile pilot he sensed how annoying it is not being able to ride my Quest 552 for a few weeks. My Zephyr is not comparable during commuting.
Mark, thanks again!
I don’t like Strava (too many unnecessary social intentions) and that’s why I use RidewithGPS (all attention for the bike ride).
So, you can follow me here …
