It’s a relatively simple repair job. Remove the crank, prise open the hub so it’s in 2 pieces but make a mark so you can put the spokes back in the same holes. Use regular wood glue on the spokes and hub and glue it back together clamping it with 2 G clamps. Leave the crank through the hub so the hole remains aligned but remove it and clean out the hole for the hub pin before the glue dries. Check if possible that the rim and crank are at right angles so the wheel will run true. If this is unsuccessful a replacement wheel can be ordered from your local Ashford dealer.
