Had a nail go thru the tread on the rear tire. Clean hole, wonder if I should consider repair or replace. This bike only has 1000 miles on it. I have always replaced tires that have gone flat, but with only 1000 miles I hate to put out $150 for a new one. Thought about taking the tire to someone like Les Schwab for their opinion. What does everyone here think? Also, I wonder about removing the rear wheel. Concerned about the ABS sensor. Manual makes a big deal about care for this.
