Hub - Freewheel Compatibiliy
I am sure this has been gone over before, but I can not find the answer.
I am building up a set of wheels for my old 1970s Peugeot.
Before I spend money on ebay I want to be sure my plan will work. The plan is to get old Campy record hubs (126 spacing) with BSC threading and install a new Shimano freewheel? I think this should work, am I correct?
Thank you
Phil

Yes it should work. The things to verify are hub spacing, which you've figured out, and also axle diameter. Some french bikes use 9.5 mm axles so the dropouts may need some filing to fit the Campy 10 mm axles. Do you plan a standard spaced 6 speed freewheel or will you opt for a narrow-spaced 7 speed? Either way, you'll need 36 mm of space between the freewheel seat (on the hub) and the drive-side locknut.
Also, check for drive side chainstay interference. Some bikes had slightly flattened chainstays for this reason.
Good luck

I never thought about axles. Just checked, axle om my rear is 10mm. The plan is to use a 6 speed freewheel.
Thank you!
Thank you!

Before you dish the rear wheel test for chain clearance at the drop-out on the smallest cog. When I built up the wheels for my '72 PX-10 (spread to 126, 7sp freewheel) it looked like there was enough clearance, but in practice I needed an additional spacer (1 or 2mm, IIRC) on the DS so the chain wouldn't jam up against the very bottom of the seat-stay when shifting from the smallest to the next-smallest cog. Though if you're only going to a 6s, you may be fine.

Thank you for your reply.
I do not know the year of my PX10, I think it is 1975 -1977. Purchased used 1977 from a bike shop..
Currently I am using a 6 gear freewheel on the original hub, 27 inch rims with clinchers (sewups were not tough enough for Chicago streets, converted around 1979). The plan was to reuse the freewheel.
The goal is get 700 mm rims (better tire selection) nice hubs and keep the weight down. The current read wheel weighs 1017 grams.
Thanks
