18T gives me wings and cracked cranks

I was excited to get the 18t to Hawes and Thursday got the opportunity to do so. It was a fast spin, I caught up to a warrior riding with artifical limb. I rolled the other way and set off on some proving succssful 18t climbs. I cleaned all the steeps and proved the 18t is here to stay, got some personal records too! I was about doen and got greedy and went up the road for a little more dirt. When I got to dirt I went into a dip in the trail and then the pedal felt real funny. I thought for sure I bent a pedal and after looking I pedaled on in uncertainty. I stopped again and dertermined to see what was up I found it, a crack half way thru my crank. Not mad or surprised about it I rode on. Time for new cranks.
