haha thanks guys I have studded tire I just waited too long before putting them on that year. yes, I was asking for trouble. on that ride I was skirting over small sections of ice I got too confident. I twitched & went hard hard, like the hand of God slapping me down instantly. no time to react, which was good, no arm out no leg out rode it down fully attached, so the impact was spread over my entire right side, ending w/ a head/helmet tap on the ground. I laid there for a cpl seconds evaluating what happened & if I broke my neck. held my head in my hands while on my back, but I was fine. surprised my camera mount didn't break off. the year before I put the studs on too early & it was a drag on moist dirt trails. but like the saying goes, better safe than sorry!
