Holdsworth Mistral restoration

If I were you I'd protect your lovely paint from the band-ons of the shifters and the front mech. Just cut some black insulating tape applied to the inside of the bands.

Some shifters I bought for my Merican came to me like this and I thought 'what a good idea' and copied it on the mech band.

Top tip that, I've also tried it with fabric tape, but it tends to fade and slip over time.
