Windsor upgrade

Hey folks. Have Windsor Super Cararra 10 speed I bought new in 79. Bike is in perfect condition - an old friend... Looking to upgrade the drivetrain. Would like to install in indexed shifters and convert it to a 20 speed. I checked with my LBS. They said that the dimensions of the bike prevent an easy retrofit. They might have to bend the frame to accomodate the new hub and cluster, something they don't want to do. Me niether. Any ideas/suggestions from you experts? Should I forget it and buy a new bike? Thanks!!!

Yeah, they'll have to cold set the rear triangle. On the other hand, it's steel. Go for it.

Hell, you can do it yourself if you're not chicken.

Chief: If the frame is spaced at 120mm that is getting a little too much to space. If the frame is at 126mm spacing then that's fairly easy. What city to you live in? I'll see if there are any frame makers in your area. Usually a frame maker has all the jigs to measure alignment and can do it for you in a matter of minutes and do it correct.

If you don't do the modifications what are you going to do with the bike? If your alternatives are either reset the rear triangle or store it away forever to gather dust, what do you have to lose?

If the bike is 120mm with a freewheel pull off the derailleurs and freewheel. Then get a BMX single speed freewheel and make a single speed. Older bikes make great single speed bikes.

Competent bike shops routinely spread steel framed rear chainstay/seatstay triangle. I've had it done, as has many others folks. It's not a big deal. It sounds to me as though the bike shop you spoke to were either incompetent/ignorant, or setting you up for a new bike sales pitch.

The only reason to upgrade to 10 speed is if you need it to keep up with training partners. Otherwise, I'd keep the original gears as long as they work well, or convert it to single speed or fixed gear.
Upgrading is just too expensive. You'll need an entire drive train, including cranks, bottom bracket, front derailer, chain and rear hub. Even with that, it will be heavier than a modern bike, maybe even heavier than it is now.

Or as a compromise, if you just want a less dramatic frame-spacing change, and to have the benefit of indexed shifting, you could go to a 6 or 7 speed freewheel and find some used or NOS downtube index shfiters.

Unless you already have the parts converting this bike to a 20 speed will probably cost you more then the bike is worth. BUT two things; if that bike has collectable value (I don't know anything about your Windsor), then the collectable value is maintaining it's originality; if it does not have any value in that area then the bike may only be worth $20, so is putting over $300 in parts and labor to convert it to a 20 speed really worth it? Also don't forget a 20 speed does not gain you any lower or higher of a gear, just more in-between choices.

A narrow 6 speed freewheel, that doesn't require a new axel or respacing, is a reasonable upgrade. Adding downtube friction levers will be pretty costly (levers, freewheel, derailer, chain) if you can find them, and they're not really any improvement over friction.

That's exactly right, except it will cost a lot more than $300 to convert to 20 speeds. You'll need a crank, bottom bracket, chain, cassette, rear hub, levers, and front and rear derailers. If the bike has a Nuovo Record group, and it's still in good condition, you could keep it the way it is. Otherwise, upgrade to fixed gear.
