Well, downtube shifters are perfectly functional... Mechanically, they're the same as bar-end shifters - the difference being where they mount. Bar-end shifters are in a more convenient location. With larger bike frames that have longer head tubes, downtube shifters can be quite far away from the handlebars and thus a pain to reach - but on your frame, they wouldn't make as much of a difference as they would on a larger frame. Still, they'd be more convenient. Expect to pay $60 for them, maybe a bit less for used models off ebay. Depending on the kind of downtube shifters you have, you might be able to get just the bar-end pods for $30 from Rivbike.com - you'd also need shifter housing, new shifter cables, and downtube cable stops which can cost up to $15, or as little as $5 if you're lucky and your LBS has a ton of unused ones in stock.

Downtube shifters have been around a long time, and you can certainly get used to them.

There's another option, which might be cheaper... Shimano SL-A050 road bike shifters, which cost around $15, and mount on the flat part of your handlebars. The right one is indexed for 7 rear cogs, and you need a rear derailleur that's index-compatible - $15-20 if you don't have that already. You'd also need the downtube cable stops, new cables and new cable housing. If you don't already have a 7-speed freewheel, you'd need that as well. Conversion is very easy if you already have a 6-speed freewheel, possibly more difficult if you have a 5-speed.

You don't need a lot of tools to do the conversion yourself. Basic multitool, a cable/housing cutter ($15-20), and if you need to change the freewheel, another $10 or so for the freewheel removal tool - which requires a 10-12" adjustable wrench or a bench vise to use. If you have the conversion done with the LBS, it'll probably cost about as much as you'd spend on the tools to do it yourself.

It's your call. If you like the bike, it fits you well, and you can't get used to the downtube shifters - then it's interesting. But you could just learn to love the downtube shifters and that'd be a lot cheaper!

One more consideration with bar ends is that depending on the bike, you may need a tandem length shifter cable for the rear derailer and if so, should always keep a spare on hand as these are not always easy to find.

Convert it to brifters, its easy if you have a DIY bone in your body. I converted my early 80s Motobecane to 9 speed Ultegra. and dropped it to 22 lbs lol... need to update teh sig.

Yeah, converting to brifters isn't as hard as it is expensive. Actually, it's not that easy either!

Well, if you find some 7-speed brifters you're off to a good start - since you can use them to shift a 7-speed freewheel, you'd likely not need a new rear wheel or to respace your frame if it's already 126mm. With my Peugeot, I got a bit lucky and found 7-speed Sora brifters for $50 and did the conversion - works great, love it!



If you want 8 or 9 speed brifters, then it gets more complicated and expensive. You need a new rear wheel, you need to respace your dropouts, and your old derailleur may well lack the necessary range of travel to reach the large cog of your cassette. So, you can easily end up spending $100+ on brifters, $60+ on a rear wheel, $25+ on a cassette, $15+ on a chain, $10 on downtube cable stops, $10+ on housing, $20+ on a new rear derailleur if necessary... And if you respace the frame to 130mm yourself (which is a bit of work), you'll need to spend $20+ at the LBS to have the dropouts and possibly the derailleur hanger realigned... My Desmarais is now 9-speed with Tiagra brifters and works quite well... Cost me a bit but I already had the brifters, and when the Desmarais was given to me 3 weeks ago it already had been respaced to 130mm and came with a modern freehub wheel. Wouldn't have done the conversion if I had to pay for all the parts...

On the cheap, go barends, you will only need a tandem cable if you run your cables aero. You can get the appropriate length tandem cables at lickbike.com (licktons). Nice thing about barends, is that you can do the whole project for about 75 bucks (for Dura Ace) but get the 9 speed ones, the newer 10's aren't friction compatible. From there you can change things around as you like . . . cassettes, RD, FD, etc.

Brifters are going to be much costlier . . . but if you do the barends first, then upgrade the rest of the drivetrain to match, eventually picking up the brifters, you won't be in for a huge cost upfront

I just did barends on my bike, and I'm upgrading the rest of my drivetrain. The only thing left is the FD and crankset. In the off season, I will probably try to score some brifters on the cheap (Ultegras).

I calculated it would cost about a thousand dollars at once to do the brifters (basically buying a whole group, and wheelset). My way of upgrading, will eventually cost about that much, however, it's spread out, and I've lucked out with a couple of deals on ebay (like a brand new DA 9 speed cassette for 58 dollars shipped!), craigslist, etc.

Besides, the barends are really conveinient, and I shift a lot (through the traffic of chicago). Easier to reach than my DT's. When everything is said and done, the lowest component level will be Ultegra.



Good luck, have fun!

It's hard to tell what type of downtube shifters are on that bike, but some Peugeot models used Simplex "Retrofriction" levers, which (IMHO) are by far the best friction shifters ever made. The all-metal Simplex derailleurs also have a very good reputation. Both turn up on eBay regularly and usually fetch impressively high prices. IOW, you may want to hang onto them; they could be diamonds in the rough, as it were.
