Kind Shock P14 34 Bicycle Seatpost Clamp Bolt - Replacement Part for LEV & SR2015 Models - Perfect for Mountain Bike & Road Bike Maintenance

When one of my bolts fell out on a ride, it was a hassle trying to source a replacement locally. You really need the beveled/chamfered head in order for the seat to adjust properly. Being able to use these was just easier in the long run.
