I have here a pretty good condition Shimano 105 5800 series chainring set.
I wanna trade as it wasn't suitable for a TT bike and need a 53/39 .
If you find that you seldom use the 11to13 teeth, why not use a 50/34, you might not even have to use your small chainring anymore in Singapore, unless you wanna climb Mount Faber. I can come to your place directly. No need to meet halfway.
