| 46mm sockets for rear wheel
I was at the Dirt Rider Expo at Stoneleigh yesterday and a company called AB Tools PO Box 112, Market Drayton, Shropshire TF9 4WA 016306 72748 were selling 1/2 inch drive 46mm (or 1 13/16") sockets that have had the chamfered edge turned down and has only 6 sides to give better grip on the narrow rear wheel nut for £15. It was second hand but still cheaper than any new ones i've seen.
just thought it may be useful. |
