Shimano Deore XT M742 Front Derailleur. 28.6mm, bottom pull. From the spares box of Sian and Dafydd Roberts, former pro mountain bikers, and along with Dafydd Davies, the founders of Coed y Brenin. There will be other items available in time, including a Marin Team Titanium, and various former race bikes. I'm selling other items two, but it'll be clearly stated which items are theirs, and the money goes to them.
