I walked past Gromit in the garage and accidentally 'tapped' the back of the right mirror with my elbow; the slightest of knocks and the glass exploded outward under the pressure of a big spring that's inside . I'm glad it didn't happen whilst I was out riding.
As we drive on the left (correct) side of the road, its the right hand mirror that I actually use (whenever I need to check my elbows), and its the right mirror that has the left hand thread, making the replacement options limited.
Having temporarily removed both mirrors, I must admit that Gromit looks much nicer. So the big question is..do I replace the mirrors or or keep the much better looking 'mirrorless' style or fit bar-ends?
