This was sent in by Stephen Langrell who had needed a mount after a mate gave him a Hayes disc brake. With his Kona frame, the Colin McRae ‘Stage One’ special no less, lacking disc mounts the only option was some scrap aluminium an old mount and an arc welder.
Once this banger of a bodge was complete it apparently “worked like a dream and to my surprise the frame held up”. We are not sure if it’s still running but he gets top marks for commitment to new technology but maybe no prizes at the local weld-a-thon.
