quick non-bike question:
when I spent time in Hanoi and HCMC, I noticed that a lot of concrete had text and what appeared to be a number written under it (usually at the ground level of concrete buildings). and i see that your first photo has that in the left of the photo? any idea about what it means?
also, i like the set-up! very practical.
how's the riding/legs? any 150km rides lately?
