    Default Bender Helix

    I just picked up 2 used bender helixes. One is stamped 9870 and the other is stamped 06AP1 or 06API (tough to tell if the last letter is the letter i or the number 1). Anyone know the angles of these helixes. Thanks.

    Paul did you ever figure out what angle the 06AP1 Helix was? Old post I realize, but I have one too...

    The way bender used to label things, I would say 2006 Apex 1000

    9870, stands for 1998 700
    I have a 9770 TP for 1997 700 triple pipe
