I have completed numerous Oly and sprint distance tris and have moved up to half IM this year. The training is nearly done and I feel ready but I don't want to wreck all the prep by being ill prepared for the race.
On previous races I have either carried no bike maintenance kit with me or just a micro pump, tyre levers and a spare inner. I figured that a puncture or mechanical was just bad luck and I would either repair it at leisure or cope with a DNF. This time I am not ready to 'cope' with a DNF.
Any advice on what bike maintenance kit to carry, how to carry it, how to reduce the weight/hassle, tips for avoiding punctures and tips for speeding up tyre changes on the roadside (I have really tightly beaded tyres) would be much appreciated.
