They are the plugs that come with new Shimano hydraulic disc brake calipers and when the caliper gets installed they get chucked in a drawer never to be used again.
Cool. I have a Mick Gray I ride more than any other bike. It’s quite different from this as it’s a mix of Columbus Zona and Reynolds 653, modern geometry and fillet brazed. If this one is as beautifully made and finished as mine then it’ll be a great bike. I’d never seen another until today.
M737 STIs, original and complete and fully functional. All logos intact. Just need a bit of a clean and the brake lever arms need a bit of a polish. £40 posted.
