What is the most economical configuration of mountain bike for mountain horse? The most economical configuration is a bald tire, which costs 50- 100 yuan. The rest should be 300 yuan at least. Bald tire configuration: 26× 1.5 bald tire is recommended. If it is smaller, it will float. 26-inch tires are difficult to control. If the peer conditions are good, you can consider 1.25 or less. If you don't want to change the inner tube and think the thin wheel is ugly, you can choose Innova Cobra tire or Max310, which are actually cheating tires in Yamasai in the name of ultra-light mountain tires. The former is the easiest to buy and almost the cheapest folding tire.
