Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Single speed conversions on sloped dropouts?

My special lady friend has a peugout that looks a lot like this:

I want to introduce her to the world of single speed and lighten up her bike in the process.
doable?

Better picture? The drop outs look pretty vertical from here, but it's hard to tell.

Doable either way - the question is, cost effective?

That would appear to be a UO8 that has horizontal dropouts... a single speed conversion would be pretty easy and if you use the existing wheels and run the chain from the low ring position you probably won't even have to re-space or re-dish that 5 speed wheel.

Peugeots can be lovely but they do have their quirks as the French used a different standard for their parts... stems, seatposts, and the bb are all proprietary sizes and threadings.

When it's all done the bike can be lightened up considerably... mine lost 8 pounds with the addition of alloy wheels, a new crank, and a new stem and bars.

You won't be able to use a cartridge bb but can convert the bb by replacing the cottered spindle with a square taper... you need a Sugino 5 for that.

I need to narrow down the exact type, but I know it's sloped and a peugeot.

I did a conversion here on an old panasonic tour bike and it only cost me around 80 bucks.
I think it'd be cheaper than finding her a new frame and building from scratch.

She already has decent bars, wheels and a seat though I might want to change her wheels/rims and crank.

We call them horizontal dropouts... your girl friend's bike has them.

The bike is a worthy candidate for an ss conversion.

why would you call something that's sloped horizontal? Horizontal is horizontal.

When dealing with bikes, if it's not vertical then what is it? Horizontal. Mainly just refering to the back and forth movement of the wheel to adjust for proper chain tension.

This bike would be a perfect candidate.

Maybe a bit confusing, but if I have to clip in on my clipless pedals, then diagonal may just as well be horizontal.

If the bike is french, you might as well forget it unless you really *love* the frame.

capolover... They are called horizontal dropouts...your bike has them... and this makes an ss conversion pretty simple.

They are not as difficult to do as operator suggests and UO8's are great riding bikes.

Or not. If the bottom bracket cups are there and in good working order you are in good shape. Just a new spindle if yours is pitted or made for cottered cranks. If it's already got a square taper spindle just repack the bearings, measure spindle length and find a nice crank that will work. A little backwards from normal but its less parts wrangling.

Worked for my peugeot.

I convert a great number of old unloved Pugs at our shop... it's isn;t rocket science but is easier when you have a parts room with a big shelf marked "FRENCH PARTS".
