I have gone riding on trails up by Idaho City twice in the last week. had a lot of fun except when my front tire slid out from underneath me. I have the stock front tire mounted and it seems that it doesn't get traction on either hard packed sandy trails or anything with a little loose top on it. I am hesitant to lean the bike into the corners due to this, I find myself sitting upright, slowing way down and turning the wheel to try and make a corner, it's irritating. I wonder if I mounted a more aggressive knobby front tire if it would help me? who knows? Thanks.
