I’m looking to change my son’s black shifter and brake cables from black to red or blue. I see Jagwire makes those colors (for both brakes and STI) but they say in only 5mm diameter. I was under impression that shifter housing was 4mm and brake housing was 5mm?? I am wrong? Who sells this stuff since none of my LBS seem to know? Thanks.
Compressionless shifter housing comes in 4mm or 5mm OD, and brake housing comes in 5mm. Jagwire is good stuff and I’m sure you can google goggols of dealers
