After a bit of spring maintenance (replaced a busted spoke and a tube with 5 patches on it), the old CCM was put back in service last week.
It caught my nephew's eye, and he asked if he could use it to commute to his summer job this year (~10 km round trip / 6 mi.).
Yes! I will happily enable family to leave a car parked when possible.
I told him a used $45 mountain bike would be far more practical & useful, but apparently retro fashion trumps utility.
Hopefully he enjoys the bike, and it returns in 4 months without too much damage!
