Are there any brake hood mirrors available that will fit the Tiagra shifters on my Specialized bicycle? I can't tell exactly what model they are; but, they say "Tiagra Double" on the front. The bicycle is about 10 years old (maybe a bit older).
(I have tried a couple mirrors that go in the handle bar ends, and they don't work well. They don't stay in position, so I don't get a good view behind me. My 30-year-old Fuji bicycle has a mirror that mounts to the brake cable, and it works wonderfully.)
