I am going up to my unckles house and I am bringing my muni. And his trails have alot of water crossings and wet trails. What is a good way to set up a muni cheap (under 20$) for this kind of riding?
Ride, have fun, wash the mud off of your tire, repeat?
buy a hose nozzel, a rag and some cheap shoes
besides what has already been said make sure you have a good pair of pinned pedals so your feet down slip off wet pedals.
Lower tire pressure may be helpful.
Riding on wet trails is awesome, dont worry about you’r muni, mine has ridden in wet trails, snow for ~2 years now. My uni is still in as good condition as it was before (I can’t really say good condition).
