24$??? That's the price of a cartridge bb.
I meant are you replacing\ upgrading the components.
I like old frames but new hardware. Alloys are better, brake designs too.
Some skinny slick\ semi slick tires will help the street ride. And keeping the weight off the frame ( I have no doo-dads) makes the bike responsive.
Hope you got an 8-spd cluster. My bike came with a 7 on a very nice Mavik rim so I've been staying @ 7 until I can't repair the wheel anymore.
It was difficult to find any quality 7spd index shifters...all plastic shell..yech.
If the frame is more to horizontal toptube design, the bikes run more to xc\road position \seat up -bars down areodynamic.
Riser bars are also a way of adapting position\ fit.
V-brakes (If it doesn't have) are a nice design, way easier to get a good clamp on the rim.
My 'way' to do up a ride is find a stinky old chromoly bike\ frame and buy a newer alu scrap bike and swap out the components -everthing that is an upgrade.
I'll seach out a used $50 bike for a wheel to rebuild, and get a set of v-brakes and long pull levers for free. (v's use a different lever than cantilever brakes.)
I just like old steel frames..but ya, check bearings, pack grease.
hubs\ bb (if original loose ball) \ headset. Look @ the races for pitting.
I didn't look, then I did....and I had to go cartridge bb.
Bikes for $24..I love it. Glad to hear your back riding...and restoring a bike.
Recycle bicycles I say.
