Upgrade 10 speed to 12-14 speeds(17 posts)

Upgrade 10 speed to 12-14 speedsjagiger
Feb 12, 2002 2:57 AM
I have an old Peugeot('75) that I thinking about using as a backup until I get something better. I'm riding a '02 C'dale R2000si, which I park on the bad days. Is it possible to upgrade my '75 cheaply so it's more useable? Also the downtube shifter have always been a bit "noodly" & I was wondering if they can be replaced? What do you think? Thanks!!

Get down your LBS and get the rear width measured - and see if they have a 6/7 block that will fit in there on the wheel you have got, or failingn that, a cheap/used wheel and block that will. Shifting not a problem as you have friction shifters.

You can replace the shifters with the sameish design in about 10 mins - look in LBS/on the web - they are cheap as chips.

Your Peugeot is steel, so you shouldn't have any trouble fitting a six-speed freewheel. Your LBS will probably charge you an arm and a leg for one (they're getting rare) but Nashbar has a Sachs for about $40. You'll want a new chain too.

Rivendell has some neat shifters for $50 at

but you can no doubt find a set cheaper. Putting them on is an easy job, but in most cases so is fixing the old ones (they're not complicated mechanisms). Have you checked into that?

It's always good to see an old bike still on the road.

Since you're not concerned with "indexing" down tube shifters are pretty universal. If you know someone who has a junk box they should be all-but-free.

A six speed freewheel should spin right onto your Peugeot with only a derailleur adjustment. Good luck getting the old one off. I'll bet that a guy who has down tube shifters in his junk box would probably have a real cheap six speed freewheel too.

A seven speed freewheel will probably require respacing your axle set a bit to the right and redishing your wheel. The issue is that the wider seven speed freewheel will be too close to the right chainstay without these other changes. Probably not worth the effort. Seven speed freewheels are a bit less common because cassettes came into fashion at about that time. You can still get new ones, but they're real expensive.

This project kind of reminds me of my college campus days. Back then we used to say "All bikes weigh the same. You can ride a 20 pound bike and carry a 20 pound lock or you can ride a 40 pound bike with no lock."

Spring is nigh, which means yard sales will soon sprout like daffodils. Every year, three hundred billion barely used old bikes are sold at yardsales, complete with barely used freewheels and chains, downtube shifters, and other parts great for 70s and 80s bikes that you want to put back in order. SOmetimes the $10 yardsale bikes are better than the beater you're refurbishing. Either way, it's simple and elegant to recycle 'cycles that way.

Scottfree's right: In a few weeks, depending on where you live, there will be about a billion bikes leaning against card tables all over America. I bought an old Trek a couple of years ago for $20--INCLUDING a Brooks Pro saddle (about $70 by itself at the time) and some barcon shifters ($50 or so). It takes a little shopping, but sometimes you get lucky.
Thanks, I check yard sales too! [nm]jagiger

Freewheel removaljagiger
Feb 12, 2002 11:02 AM
Luckily, I've been able to remove the freewheel with no problem. I had spokes starting to break, probably rusting.
I've been getting a lesson in truing.

I'll have to check around on the parts....sounds like I could get away pretty well by just doing some leg work.

Also...I think i own one of those 20lb locks. Actually, I bought it for my C'dale, but don't use it cause it's so heavy. I'll have to loose a few more lbs & take it along.
Thanks for the help.
7 Speeds & morejagiger

As pointed out, I may find cheap parts/bikes or a 7-speed wheel at tag sale. I image that I could swap wheels. Any things to look out for or avoid? Would 8 or 9-speed work without major surgery? (the more gears the better) Thanks

What you have, if all the parts are there, is the workings of a restored classic. There is sort of a growing under current of vintage bikes out there and the possibilities are very real. Several companies out there that do complete restore of a frames finish with decals, parts are for sale and if you have the originals that just need service, like the hubs, you could have the rims relaced with new hoops and a new freewheel, new chain, etc. and it looks like it did in 75. I am currently trying to recover a bike I gave away to do this exact thing, full restore to better than new. The parts are out there on the net, you just have to look a little, type in Vintage Bicycles and the door to restore has opened. I sort of see it as something different to ride in a nostalgic sense; newer is not always better.

I'll rush to add it's an acquired taste and not to everyone's liking. There are hassles and headaches in dealing with an older bike. You have to see the restoration/maintenance as enjoyable in themselves, a 'hobby' (hate the word) that has its own rewards. Just like vintage cars (something I also dabble in).

I personally think it's fun to scour the Web and the world for obscure parts to keep a good machine going; I doubt the average cyclist out there (and on this board) would derive the same satisfaction. What you or I might see as a restorable treasure is more usually dismissed as a "$50 POS," and the odd thing each assessment is correct depending on how you look at it.

Bikes are like quantum physics that way.

Is a bike I bought in 1978 when I started college. Last summer I gave!! gave the bike away to a local youth ministry to rebuild and use. It was a mans 57cm frame and these are kids so chances are the frame/bike is still sitting around somewhere too large for there use. The other thing about the bike is it was recalled by the US Consumer product safety people; seems that brand of bike was sold with a fork (DEATH FORK) that breaks in 2 without warning. So I want to get it out of the public harms way before someone kills themselve. Then I will decide what is best for it, new fork or part it out. Also looking around for a late 70's Raleigh, lugged 531 frame.

If I recover the Viscount Sebring, I will restore to better than new, I already have visions of riding it again. Hopefully get some good before and after pics.
Good luck with your search!! [nm]jagiger

Sheldon Brown's site and Classic rendevouz? are great sites about the restore biz. Lots of links to parts etc.
