Hey folks. Just wanted to show off my completed SS project - an older Jeunet. The Atom hub on this thing wouldn't go fixie, and I really don't think my knees would like it anyway.

I have to say, everyone was right about going SS. You focus so much more on the "ride" and if a hill is coming up, you just suck it up and pedal! I remember now getting your speed up on the preceeding downhill to help on the following uphill, just like when I was a kid. I'm loving it.

Anyway, there is a thread on the Classic & Vintage forum if anyone want the whole story, from when the guy gave me this bike to now. And there are some before and after photos.

Take care!

Nice Bike! I love perusing the Classic & Vintage forum. Those people know EVERYTHING about funky old bikes.

Nice bike.

Watch out for the bunny.

Let's play guess the gearing! I guess 52/20. Next?

Found it at FG Gallery:
44 (44 x 16 drive train)

I can't believe that it's a 44 chainring, it looks huge. Unless those are 125 cranks, of course.

Guys, it's 52 X 20. I decided to count it today. How does this rate with what others are running? I'm wondering if I committed a SS sin by ditching the smaller front chainring and keeping the large. On this bike, it wasn't really possible to run just the smaller since the little chainring was riveted to the large, and only the large bolts to the crank. Therefore, I removed the smaller. I've also got the 14 and 17 cogs that I could put on the rear to go lower. On this French hub, you just thread them on/off.

To me, it looks kind of cool with the big sprocket up front. The chain has a neat profile.

Did I do wrong???

Your knees will tell you if your gearing is too high. Your heart rate is tell you if its too low. Its all a personal choice. Ideally the larger the cogs the less wear on your drivetrain. If you are happy with the current setup.....by all means keep it.

BTW great bike ;)

When I started riding fixed, I started out with a 52. I went as small as 15, and as large as 20 for the rear. My knees didn't care, but I did. It was like getting a train started with that ratio. This season I've listened to the forum and have tried a 48 with the 16 and the 17. I rode that all winter, well, 18 and 20 all winter. I'm running 48x16 to commute daily to work, and am loving it. The spinning is great, and I don't feel like a train off the line.

52x20 = 70 gear inches on my chart. That is just about considered ideal for all around urban usage with some hills. If it was used in a totally flat area you could go to a 19 rear cog which would give you a 72 gear inch ratio, producing a higher possible speed on the same flat terrain. Either way if you like the feel of the bike, who cares if you are running what everybody else thinks as correct gearing. It's your bike. and there are no rules , except you own, when it comes to your bike.
