I don't carry a chain whip. I sometimes carry spokes. I have lost drive side spokes but did a mix of limping to next bike shop or bending/threading.

I usually carry a Kevlar spoke: https://www.amazon.com/FiberFix-Emer...dp/B001GSMQZC/ I've used it exactly once as shown in photo below. This was in western parts of Argentina between Salta and Mendoza where there is some small towns but also occasional two-day gaps and not a lot in way of bicycle shops. This was with a fellow German cyclist who was on a parallel journey (we first met in Baja, then leapfrogged/cycled some days in Argentina including the night we replace his spoke). As I understood things, this emergency repair may have lasted ~900km until he got a more reasonable replacement in Mendoza.
