We're currently using SRAM PC 971's in rotation on the business side of the Longstaff (where the gears are), and a KMC Narrow on the timing side.
In the interest of redundancy (need to carry only one type of spare chain segment & magic links), is there any reason why I shouldn't just swap out the KMC for a couple of 971s joined together so we have the same chain-type throughout?
FWIW - we stretched the buggery out of the KMC timing chain over the course of the winter - the EBB started out fully forward, and ended up fully back - which I took as a sign that the bike needed a service
.
Just wondering if a 9-speed chain might not last on the timing side - being thinner?
