i somehow broke around the weld near the spindle on my mrp bones combo cranks. the left arm is the only one actually broken they are old and i used them on my hardtail for 3 years now with plenty of cases on them. it was below freezing lately and i did happen to case a really big jump the other day. but they actually came apart when riding on the road.<br /><br /><br /><img src="http://ll.broadbandsports.com/images/5188_mountain_biking_broken_bones.mpg.jpg" alt="broken bones" title="broken bones" width="150" height="90" alt="broken bones"/>
