|Where would you go to get a 6 speed friction derailler?||9WorCP|

|My friend laid down his vintage (late 80s) bike last weekend and hosed the Giepemme(sp?) derailleur that was hanging on it. A real shame since it looked so classy and shiny. So where to get a suitable replacement? What are his options, if say, he wants to upgrade? The wheel is trashed as well. Should he get a 7 speed hub? I know nothing much about these bikes thought I'd turn to the much respected cycling brain trust we have here.

|Any derailer will work in friction mode.The main consideration being that it have enough capacity to shift to the largest cog in the rear. Most derailers will handle 28 to 30 teeth ok,but if the large cog is greater than that, a MTB derailer is often the better choice.7 speed is a viable option since he has to have a new rear wheel anyway.Keep it friction, and there are almost no issues and the cost is much less.|

|You obviously aren't very knowlegeable about bikes, so make sure that the bike doesn't have a bent dropout before you go buying a new derailleur.|

|I'm somewhat insulted by your post. I know a bit more than you assume. As far I have seen the hanger and dropouts seem fine. I'm sure he will have the alignment verified before proceeding. We were just discussing earlier what his options were. It's not like we're running out, buying the parts and assembling it tonight. Really buddy, you have to stop assuming anyone who asks a question is a nimrod. If I were proferring bad advice that would be another matter.|

|look on ebay for a used campy nouvo record derailler, you should be able to get one for 25-40 bucks and then get the wheel rebuilt on the same hub for 40-50 bucks. It depends though, on how vintage he wants to keep his bike.
Otherwise he can fit a 7 speed drivetrain in it with no modifications and if he wants to stretch the rear dropouts a couple of mm he could even put a 10 speed setup. one thing, you are not supposed to expand anything but a steel frame.

|1. I'm not familiar with that derailleur. How did it mount onto the frame? You need to find a derailleur that mounts the same way. This sounds to me like a European bike so you may encounter thread pitch issues. Don't worry about 7,8 or 9-speed, they'll all work just fine.
2. Rear derailleurs are rated for largest cog and slack take up. Largest cog on the back is self explanatory. To calculate slack take up, subtract the number of teeth on the smallest front sprocket from the biggest front sprocket. Do the same with the back and add those two numbers together. Your local bike shop will be able to advise you on suitable derailleurs.
3. To get a replacement rear wheel, you need to know your wheel diameter and rear drop out spacing. There will be a lot of choices to make assuming you want to get a replacement of similar quality to the original wheel.
4. Being honest with yourself, how's the rest of the bike? Just a new wheel, freewheel and derailleur are going to cost at least $100.00. My bet is there will be some additional issues that will wind up costing you some more money. I have a customer who, against my advice, bought an old Gitane tandem. He has since invested enough money in it to have bought himself a brand new Burley tandem. All he got for his money is an old bike with scary brakes, that doesn't fit either him or his wife, and that is just barely rideable. Now that he has spent all his money, he can't afford to buy the bike he really wants. What a shame! Think it through before you start spending money on an old bike.
Brand new bike store quality bikes start at about $350.00. For your extra money you get to pick a style of bike that matches your riding life style. You'll get much crisper shifting and brakes. Every single part is brand new, designed to work with every other part, and sized to fit you. You'll also get a new bike warranty and probably a maintenance agreement of some kind.

|Your last point (4) is valid if someone is just looking to buy an old bike to 'upgrade' and get by on the cheap. Wrong-o way to go. But 100 bucks isn't anything to spend on fixing a vintage bike you already own,love and ride. My impression from the original post that this bike was the latter.|
|WALMART...seriously you should try to find a ...||spookyload|

|Sachs Huret Jubilee. It is the lightest rear deraileur ever made. It had this crazy pulley on the bottom that had no teeth, just round. It was light as hell and looked totally minimal. Funny thing was it was durable. I used it for cyclocross for three years and it never broke. You can probably find one on eBay or at www.loosescrews.com. A used campy super record would look good too.|

|I agree with the poster who suggested your friend just get another bike. My wife had a vintage, made by Sante Pogliaghi himself mid-eighties Pogliaghi bicycle with Super Record that she loved to death and rode constantly. Then, in the late 1990's, things started to happen - like her seatpost fixing bolt shearing off. Finally, one day, one leg of her fork just twisted off because of fatigue. There was no rust. It just gave out. In other words, no matter how much your friend loves his vintage bike, there's a good chance that it's no longer as strong as it might have once been. What's more, the bike my wife replaced the Poghi with, a Colnago Dream with Campy Record 10 speed, is so much better than the old Poghi, she hasn't shed a single tear over the change. Not that the Poghi wasn't a delicious entity in its day. It's just that Time Marches On, and that old age eventually strikes even the mightiest of steeds.|| |
