Semi OT, Natural Rubber Tires?

[Charles M]

I have an Old school meets new school build to do and am Wondering who might still make a gum rubber toned tire? Tan sidewalls with natural rubber tread (or like it...)?

Any ideas would be GREATly appreciotos

Not sure what you mean by "natural rubber tread". These all have traditional, carbon black tread.

I have some Veloflex open tubulars with natural sidewalls. As a bonus, they are one of the best riding tires I have ever tried.

Yeah sorry there. I meant a neutral color tone, not neccesarily the actuall material make up...

Brown / tan sidewall and neutral tread color...
