Shuffling bikes around
Wound up doing some impromptu bicycle mechaniking last night. My son had an accident on his Bridgestone MB3 (a classic bike) 
and the upper headset bearing race broke. He’ll also need a new left Shimano Deore shifter and brake handle.
The accident was caused by some broken pavement – thank you Town Of Normal – though my son is pretty much OK. But it will take a while to scrounge up the ^^ quality parts (eBay will have them) and he needs another bike to ride in the meantime.
In the garage was an old GT hybrid bike in pretty fair condition but unused for several years. After a quick trip for parts, I fixed a flat tire, installed some pedals, a kickstand, a new seat, some reflectors, and made adjustments. It has an exceptionally large frame so *presto!* a usable bike for my 6-foot 2-inch son.
Now for the slower, more exacting search for parts for the Bridgestone.
After seeing what you did to my bike I have full confidence in the fact you will have your son’s bike working in no time!
Good luck with the parts search!
