Although this isn't truly vintage, it's likely as vintage as I'm going to get. It's my 4th bike build, and I do have a lot of fun rebuilding frames into something rideable. I'm building it as a single speed, and one of the pics shows my Rennen Rollenlager chain tensioner that came this morning temporarily mounted. Some parts I had in my parts bin; a few more I was able to find NOS at a decent price; and a couple more I bought used. As you folks know, the cost of building a bike can get away from you quickly, and I'm trying to do this without throwing a bunch of $$$ into a hole. My NOS wheelset is supposed to arrive today. They are a discontinued 700C set from all the way across the country, and had to take a few extra days' detour due to this nasty weather we've been fighting. Another part due to arrive tomorrow is a 1 1/8" quill stem that accepts a 31.8mm bar. I hope to have the bike ready to go in another week or so.

Wheelset arrived today, nice and trued by the seller. This bike is certainly different from my Trek hybrid, on which I currently run 700x50, and could fit even wider tires. On the Specialized frame, the 700x50 fits fine up front, but won't even come close in the back. I took the new rear wheel and mounted a used Bontrager 700x45 I had hanging in the garage. It fits fine with plenty of room around the seatstays, but the clearance around the chainstays is very close. The wheel turns without rubbing, even when I put all my weight on the seat, but it's close! I'm still going to try it with the 700x45 tires. Worst comes to worse, I'll drop to a 700x40 in the rear.

Went to the LBS today to pick up tubes and tires, Bontrager LT2 Comp 700x38. Narrowest tires I've had on a bike since I had a single speed, coaster brake, drop bar 26" bike in my late teens. I considered going wider on the front since the fork has so much room, but decided to stick with the same front and back. Getting close, but still waiting on a couple of other parts to arrive.

The adapter I needed to mount a bar with a 31.8mm center to a 1 1/8" threaded fork arrived today. With the bars I chose, I think the bike's lines have a 70s sort of vibe. I'm using new-old-stock BMX levers to actuate the brakes. I'm still amazed what great shape the frame and paint are in for a 22 year old bike. Makes me wonder if it was kept inside, and why they stripped the frame in the first place. Just need to adjust the brakes and set up the drive train, and I'll be ready to go.

COVID bike #3 is complete. In this photo, the chain was way too slack, even with the chain tensioner, but removing a link made the chain too short. What to do? Wait until the next day and drive to the LBS to pick up some half-links to adjust the chain length, or . . . change the rear cog. I figured changing from an 18T to 20T cog would take up some chain slack, but would it be too much? Only one way to find out.

A couple of hours later, I'm riding the thing in the dark in front of my house. The complete silence of a well tuned SS is beautiful. I really liked the feel of the 700x38 tires. We'll see how I'm thinking after I've put some miles out on the trail. Final gear ratio is 36:20, and just over 49 gear inches. It felt good on the slight inclines we have directly in front of my house. I don't plan on doing any hill climbing, just rail trail riding.
