Lately I've been focused on building a new commuter bike (1983 Schwinn World) but this bike is on deck. I traded a set of wheels for this frame last fall. I've always wanted a prewar Schwinn to build a klunker out of, now I can! I've been collecting parts lately. I'm aware that these bikes came with a variety of headbadges, and since my bike didn't have one it really leaves only one choice for a klunker, Excelsior. The obiqutous Morrow hub has also landed, and a ridiculously long exerciser seat post. The crank/bb came from the same bike as the badge, supposedly a '37. I absolutely love old Schwinn's, but I can not stand the four leaf clover chain ring. I also want this bike to be more versatile (single track, etc.) than just ripping downhill, so I needed better/shorter gearing. I was on the lookout for a child's 18t chain ring, and this is what I recently found. Not sure what it is from, but it's reasonably good looking and will get the gearing (1.8:1) where I need it to be. As you can see the plan is very traditional mid 70's, but making it a better all around mountain bike will warrant a few changes, I'd love to hear your suggestions. The chainring is of course one. A Brooks B72 was the saddle of choice back in the day, but there's no way I could pedal for very long with that Lay-Z-Boy under me. So I'll need a slightly narrower Brooks, hopefully still sprung? The huge cruiser bars will also be a no-go, but I'm not really sure what will work. I want something much narrower, and period correct. Pedals with more grip as well. Vintage BMX?? I imagine I suppose I'll try to find an original stem and front hub, or should I go high flange? The hardest part to track down will be an original prewar fork with truss rods. I've been looking for months with zero luck.... The biggest, and probably the most subtle change will be wheels. I will convert it to 650b/27.5. It should make for a very fun rig. I'm hoping to have it ready for SSUSA in Bellingham this July, but that might be a little too ambitious. I'm considering building it up as it is, then tearing it down and restoring the frame at a later date. Comments and suggestions arewelcome. Especially on how do I get that .... old seat post out???
