Stainless vs galvanised derailleur cable: the real lifespan

The debate

Cable prices range 1x to 4x: galvanised Shimano (2-3€), stainless (4-6€), Optislick PTFE (8-12€), SRAM Slickwire polymer (15-20€). Worth the premium? We tested.

The test

4 identical Specialized Allez, same 105 R7000 groupset, same use (30km/day commute, 6 days/week, rain included). Different cable on each. 24 months monitoring.

Verdict

For daily commute in rain: Optislick or Slickwire pays back in 12 months. For weekend leisure: galvanised is fine, change every 18 months.
