Input:
This helmet is working out just fine.  I thought there might be a problem as the foam inserts were so weakly attached but they've all held on ok.  I must've used the helmet for about 50 hrs of riding so far.  The sizing dial works good but the straps are not my favorite.  They work themselves loose every other ride and the cinch that comes on both sidestraps seems to have no real purpose.
