Congratulations and welcome to the Ironman owners fraternity. You acquired the hard to find Master at an incredible deal.

TIRES - I run 28cm, but I would recommend 25cm as there is little or no clearance at the fork casting. Go for white walls or white striped tires.

CABLE HOUSING - If the pink housing needs to go, white or Jagwire Titanium braided would look sweet.
