Peugeot was a major user of Simplex DOs. I am most familiar with the version that has the cylindrical plastic insert to hold the axle position adjusting screws from the 80's and early 90's (I dunno, but there seems to be something about "Delrin" plastic that Simplex was really into it). Otherwise, Many other French makers used Simplex DOs but Peugeot might be the biggest of them. Good thing is, I never really heard of any problems with Simplex DOs, as you might with other brands cracking (I think some Suntour made DOs did that??). Simplex DOs might look plain and simple, but they do stand up to hard use very well.

Do you ever look on eBay for them? That's where I bought a set.

Hello! Quick question.

Curious if your PA10 with the forged Simplex drop outs is high tensile or Reynolds? Thank you very very much!

The PA 10 always used Peugeot hi-tensile tubing in the frame and fork. A Reynolds PG 531 main frame came on the PR 10 and full 531 on the PX 10.

Here is an example of the latest version that has been worked on quite a bit. Peugeot Pro 10.

Thanks for the info.
