bet with my son I couldn’t rebuild an ancient peugeot tourney I bought a wheel taking a freewheel type hub choosing 13/34 as Im old, please advise on derailleur chainwheel chain and shifters and if I can buy them altogether with you
Difficult to advise without discussing more but the following would PROBABLY work;

BB - SJS Cycles part number : 31L110 - (110mm)
Front mech - SJS Cycles part number : 46426
Rear Mech - - either depending on fitting.
Shifters - SJS Cycles part number : 35521 -for STI OR SJS Cycles part number : 21015 - or Downtube
Chain - SJS Cycles part number : 18592

What is the width from the smallest cog to the biggest?
23 Mar 2019
I do need to know the width to check the frame's clearance as it's for an upgrade from 6 speed to 7.
Thank you very much
Thank you for your enquiry, the width of this freewheel is 34.65mm.

Is Gear Selection As Good As Shimano? Is This Suitable For An Indexed System?
24 Mar 2017

As these are a direct Shimano copy the shifting should be very close to Shimano. These are suitable for an indexed system.
