Replacement Dropout bolts black steel, set of four bolts and four nuts. All black plated steel and a perfect replacement for the weak aluminium bolts originally supplied on the G line. The nuts have a toothed shoulder so you'll probably get away with just torqing the bolts while holding the nut with the tip of your finger. So you probably don't need a chainring nut wrench. You can replace the two on the left side by just changing them one by one whith the wheel still in the bike and the whel nut tightened. On the right side you need to loosen the nut a few turns and spread the dropout out a bit with a screwdriver to let the dropout bolt fall out. This is the case for the Afline version. I haven't yet tried it on the Electric.
