Worked on the rear wheel last night. I wanted to replace the alloy MTB wheel with a steel wheel like what the bike would have originally come with. I got a suitable wheel in a trade with
@idiotboy at the beginning of the build-off. It came without a spoke protector. My primary objective was to find a period-correct metal spoke protector and get it mounted behind a standard-ish 14-28 freewheel cluster. I know a dork disc isn't necessary if you adjust the derailleur correctly, but for me they add to the chromed-out musclecar look that these bikes evoked when they were new.
My first thought was to use a Schwinn setup like this, as I have a couple of them around:
But I have this weird self-imposed policy: I try to use only Schwinn parts on Schwinn bikes, and the converse is that I try to put non-Schwinn bikes together WITHOUT using Schwinn parts.
I have this old Ross wheelset around off a 26" Europa 10-speed. For some reason, I was hesitant to rob the freewheel and spoke protector off it... you ever have some part you're hanging on to like you may use it someday, even though you know you never really will? I used these wheels for a little while on a Speedster masquerading as a Collegiate, and they served me well, but I have since picked up a few real Collegiates and blown the Speedster apart to be reincarnated as a BMX cruiser. Going forward, I can't think of any bike I'd want to build that I'd need this size wheel for. So the freewheel and spoke protector were yanked for this build. I was actually pretty stoked to see the little 333 on the spoke protector to match the one on the derailleur.
This is where I confused myself. First of all, I had completely forgotten that the wheel I'm using had a freewheel on it when I got it. Then in trying to find the best freewheel in my stash to use, I settled on putting a Schwinn freewheel on with the Shimano 333 spoke protector. The result was that in low gear, the chain and the derailleur cage both interfered with the protector.
I was hesitant to use the Shimano freewheel from the Ross wheelset for two reasons: first, it felt a little crunchy when spinning it compared to the Schwinn, and second, it takes a VERY small oddball freewheel tool which I only happened to have because I bought a cigar box with some odd bike tools at a yard sale.
I tried drizzling some Marvel Mystery Oil into it while spinning it, and it smoothed out considerably. So I spun it on, and it better work for a while at least, because the only way it's coming off now is if I take the axle out to get the freewheel tool into it.
(It was only this morning after all that excitement that I noticed the Falcon freewheel that I got with this wheel sitting at the bottom of the box of parts for this build. It takes the larger, more common Shimano tool that fits over the cone/locknut. I could've used that and not had to worry about repairs/disassembly. Oh well, I guess we will jump off that bridge if we get to it.
)
The good news is that now everything is spaced and aligned as it should be.
Then I went to adjust the derailleur and had to address this little issue:
The Shimano Eagle derailleur off the aforementioned Ross Europa donated a limit screw.
Mounted up that old 24 x 2.125 and tightened and adjusted everything, and it all seems to work correctly. And the big fat tire on the back really changes the look as compared to the 1.75 MTB tire that was on there.
Upcoming steps: chain guard, maybe rejuvenate this chain instead of replacing it, address the lower headset cup that seems to need a shim...
