    Stripped 321 Lefty hub cap - help !

    Tonight was the night I was going to take this bolt out to measure it up for a Ti replacement one . I knew the aluminum one in there wasn't going to last .
    It felt weak the last time I took it off .
    So SOB if tonight my allen wrench just rounded off in it
    I thought my Easy Out tools would rescue it ........ Nope ..... totally round now
    Has anyone else had the same dilemma and figured out a way of getting it off ?
    My next thought is to drill the bolt but I think its hollow .
    Even if I did , the Easy Out would probably just round out in it again .

    Hey Craig,

    Get one of those (high quality) extractors you pound in. Make the appropriate size hole, which will be easy since it's aluminum, then you tap in the extractor and it will bite and you turn it ccw with a small wrench or vice grips. May I stress that this is a situation of "cheap man buys twice". I got my set at TSC for about $30 or so and it's done wonders for me, including completely seized steel crankarm bolts overtightened from the factory. I've also done a stripped rotor bolt with it without damaging the hub.

    Use a left-handed drill bit to make the hole for those. It won't further tighten it AND the torque of drilling may actually cause it to spin out (very likely).

    With a Dremmel , do a straight 'groove' and use a very large flat screw driver.

    Thanks for the tip Yann
    Heading to TSC now .

    Left handed drill bit ?
    If it was that loose the Easy Out would have gotten it .
    The thought with the drilling was to compromise the bolt enough that it
    would no longer hold the cap in place then remove the cap with a red
    Park spanner .

    Got it out .
    Got the square Easy Outs Yann showed and it was over in 30 seconds .
    Just tap it in with a hammer , turn it and out it came
    The square edge ones get a better grip then the spiral ones I have .

    Kudos on a job well done.

    Is that 321's "new and improved" bolt, or their original one?

    This was an early on I believe as I got mine when they
    first came out .

    Yeah, they came out w/ a better bolt soon after product release, as the original was rounding out upon initial install. You should contact them for a new/improved one FOC.

    Was the improved one aluminum as well ?

    Yeah, was alu too, but different size hex or somethng or other.

    I would stick w/ the stocker for durability.

    BTW, it looks like anti-sieze was used on your bolt threads. If it was, and you torqued the bolt "to spec", you very likely over-torqued it.

    I had a similar problem with my 321 hub. Instead of using an extractor as pictured above, I managed to get the outer nut off and then used a vice grip to get the bolt off.

    I spoke to Sam about the issue and they had introduced a newer version made from a tougher aluminium. So far so good.

    I had the same problem

    It happened while I was packing my bike for a trip to Fruita. I had o call around to find a cannondale shop with the stock bolt. It was blingy and a bit lighter but the 321 bolt was hardly worth the pain.
