Hi,
First post, been searching for a while. After 37yrs I'm back into biking with my old custom Sonnet bike. I can't find it on Google to find out if it is French or not. I had it built while in the Philippines for $310 in 68 or 69. I rode it around Clark AFB about 20 miles every day, very flat. It's a nice light (24lbs) road racer with 52/45 crank set and 14/24 5 gear freewheel. Very hilly here in Pa. and I need to lower the gearing some. I'm looking for the easy cheapest way to try it before I invest in a better bike. The freewheeler is an Atom and the crankset is 3arrows???? Which is the best way to change gearing? I'd like to ID the frame so I could change the BB but I don't know what I have.
By the way, thanks for all the good info. Did a lot of reading here and learned a lot. Did a search on changing gears and have myself confused right now on which way to go.

Thanks Staledale
