i got a dumb question..when converting to hex's on the front end of the b4.1 and using clamping style hexs (avid in my case) is there any reason to run a roll pin thru the axle? like there is no drive to make them slip and it seems to be attached well with out it..i didnt see any mention of them in the required parts list for conversion..thnks in advance..oh and is there any options when it comes to a low profile front axle nut.all new tires and hexs ready to go and none of my lhs's have the associated ASC9880,,any thing else or another brands nut work dialed?
