    Nishiki Alien - Headtube size

    Can anyone tell me whether the Nishiki Alien (the models with the bolt on chromo rear end onto the al front end are 1" or 1 1/8" headtubes.

    I know the pros and cons of e-stay bikes, I don't need a run-down on that, just want to know the headtube size.

    Thanks,
    Grumps

    I remember those & they were solidly in the 1" head tube era.

    Watch the head tube - some of those frames weren't heat-treated.

    Check carefully for cracks.

    I'll leave it in the sun.

    Seriously, that's a great tip, I appreciate that advice.

    The one I'm looking at has had a repair to the inside of the headtube so I assume a crack formed so I'm going to take a wild guess that it's one of the non-heat treated ones. Shame.

    Reminds me of Ellison frames built in Houston, Texas,I had a1990 model and was great until the top tube snapped just in front of the seat cluster. I heard later that he used a pizza oven for heat treating. Look closely at any 6061 aluminum frames for any cracks.

    The first, all steel Alien may have been a 1", but all the alloy framed Aliens were 1 1/8". BTW, the Ariel, which was the continuation of the former Alien steel frame, Also has a 1 1/8". At least it did by 1992.
