Guys: this chain was well before indexing systems or Uniglide, both which spec serious outer link retention needs, and as such the pins have no peening or end riveting. As long as the usual care is taken when using a chain tool to not ovalize the side plate's pin hole and one centers the pin WRT the side plates all should be good (assuming no stiff link).

Now having said all that people have a way of finding the weakness of a system. In this case and with current assumptions this means that today's riders will likely shift under power and find out why current chains do have end of pin treatments that help reduce side plate pry off. Chains of the pre indexed era worked fine till riders asked too much of them and didn't soft pedal when shifting.

So if the cogs have no shift gates, lift pins, pick up teeth or even twist teeth (Shimano late 1970s) the Reynolds chain should be fine. Just learn to soft pedal and shift before you need to. Andy
