The stock gearing is great for most everything trail related. Keep the chain well lubed & adjusted. When you change your chain & sprockets, you will know if you want to change your gear ratio or not, but do go with the o-ring chain, they are far better.
Your front brake on the other hand, now thatâ€™s not right. Is it a drum brake? Better have a good look at that.
