What brake calipers to fit a Peugeot 501 frame?

[Ugo51]

Hello everyone,

I recently started building up my Peugeot Ventoux frame, for which I have a few RX100 components, including the brake calipers.
It was only when I went to fit them that I realized that the holes in the fork and frame don't take these calipers as the bolts on them are too short and thick. I had a pair of Weinmann 500 and they obviously fit fine, but they are in a bad shape and not really fitting with the rest of the components.
Do you know what calipers I could fit?
I tried googling "bike brake calipers with thin bolts" but, surprisingly, didn't come up with much

Thanks

sounds like you need calipers with external nuts, not the hidden allen key type

That's right.
I now see they might also be referred to as "traditional nut style" calipers.

Usually the back of the fork crown can be drilled 8.5mm iirc - get advice if you're not sure, but there's normally plenty of metal on the crown.

You can usually fit a front brake on the rear - I wouldn't drill that because the tube often isn't strong enough.

That way you can have decent modern brakes without paying £70 for the nutted twin pivot tektros.

I've got some Weinmann side pulls you can have for postage. Let me know the brake drop if you're interested.
