after many years of cycling i did my first charity ride this past weekend- i couldn't believe how many
people showed up with bikes that had near flat tires. the on-site bike mechanic spent quite a bit of time
inflating and telling people how the bike they were riding was either too small or too large or the seat was at least
8 inches too high or too low.
i overheard the mechanic tell one guy that the stem on his mountain bike was up so high it was in danger of breaking off
during his ride since there was only a couple of inches left in the head tube. the mechanic said it was a huge safety issue
the rider told the mechanic "i've ridden 10 miles so far this year and nothing has happened, just leave it be, besides if you lower it my back will hurt"
