Jim mentioned putting it under the visor, I think the perfect location would be in your tire, would always be there when you needed it. One club member found this works perfect for your tire tool, store it inside the tire for when you need it. We only found 1 in the rear while changing a flat he had on the trail, we figure he put the other one in the front, you don't want to throw your tire out of balance. Worked for 2 races anyway. LOL
