These will cover your downtube shifter bosses when you are not using them.

We made it into a shape that will match perfectly with the outer stoppers from Shimano and DIA-COMPE.

When you build a Surly straggler or Cross x Check as a front single bike, you are able to make it look slick.

You could of course use them for single speed modified bikes

Sold individually. Same colored bolts are included.
