Went with the Continental 5000s and all went well. Hard to get on the rims at first. bike went great, a lot lighter than his 24" Frog racing bike. Took nearly 2 minutes off his 4 mile bike ride. Ended up competing in a duathlon instead of a triathlon in the final race of the season due to bacteria in the lake
