At 68, I'm guessing most here are younger than me, but more knowledgeable about bikes.
I've had a Motobecane 10 speed since mid 70s. 5 years ago I got a 21 speed hybrid for commuting and exercise.
I didn't think I needed a road bike and wanted ability to get in the dirt, if need be.
When I can I like to take 10-35 mile rides, (to keep my doctor happy)
We have some very good bike techs in our local shops, but I still like to think I can work on some things.
In addition to the I'net (thank you BikeForums), my text references are my 1973 edition of "anybody's bike book" and the 4th Edition of "Zinn & the Art of Mountain Bike Maintenance". Sometimes they disagree. Being an old fart, I need clear and simple instructions.
So be patient, eventually I get it.
BTW: n7eoj is my Amateur Radio callsign.
