Hmmm, I kinda think that bar tape needs to go white if the saddle's gonna be white. Or maybe someone makes a navy bar tape that would be even better.

If it were my bike and I was gonna run tan sidewall tires all the time, I'd likely get some Tan bar tape and a tan Charge Spoon CrMo saddle or a Brooks honey saddle of some sort if I was a big spender.
