Peugeot Fork

Hi Bobs, I recently bought a 70's Peugeot Road bike (Reynolds 531 tubing). I bought it used, and
found that the stem was undersized for the fork tube. The reason for this, I found, is that the
upper part of the fork (inside the head tube) is bent enough so a proper sized stem will not fit.
While trying to straighten the fork tube, it cracked vertically (partial crack, could be used, but
inadvisable I would think). This is a quality 18 speed bike, weighing about 22 lb., so I do not
want to trash it, or sell it for components. Tire size is 700c or 27x 1 1/4. What are my options
for replacing/repairing the fork? Will a standard US/ISO one fit? Must it be a Peugeot fork? Are
the forks on other French bikes the same size etc? Where would you expect one could be found? If a
US fork would fit, what else would have to be changed? Any help will be appreciated.

Ideally, you want a french threaded (m 25x1) fork of the same material, rake and clearance along
with a french (22.0mm) stem. Those will be difficult (expensive) to find. Converting the front if
the bike to a BSC (1"x24tpi) fork with a new ISO headset and a regular ISO 22.2mm stem is a common
solution if "restoration" is off the table.

Yes, the wheels might be 27" or they might be 700C. What year/model is it? You could also look on
the tire sidewall. 27 nch tires are 630mm and 700C tires are 622mm.

Andy,

What I meant by the tire size is that the bike can take either size, depending on the brake
adjustment. I put this in just in case it had anything to do with the available fork sizes.

I will consider restoration with French parts, but most likely will convert it to US..

Thanks for your help
