    New Ultimate ISIS BB 145g with bolts, pics inside

    Just got this new BB for testing. It's the first one from the danish company New Ultimate. They also offer a seat post at 95g in a 27.2/250 size and soon there will be a 350mm version.
    The axel on the BB is made from scandium aluminium with M15 bolts. The bolts are very long and hollow, which helps stiffen the BB. Still this BB only weigh 145g in a 108/68 edition. The quality looks very promissing. The bearings aren't replaceable. I will soon have it tested on my blur. It's intended for roadbikes, but lets se how it performs in the mud.

    Nice feature, the allowed torque is molded into the bolt cap.

    Very cool. but how long will it last? There was a post recently about the durability of the aluminium bb's. But then again, this is scandium aluminium. Im not sure exactly what that means. Is it aluminium with scandium in it?

    scandium is a composite, its got all sort of goodies in it to my knowledge. I wonder how much that scale cost

    Scandium makes up a small percentage of the metal. It is still aluminum, but with scandium.

    Good old metallurgy?

    Heres an article i read last week when my friend and I had this discussion about the benefits of scandium: Scandium is in the periodic table, but i don't think they use pure scandium here..

    Looks a bit like the FSA ones to me

    I have had an FSA Platinum Pro ISIS BB (which failed) and this looks a bit like that. The long, strengthening bolts seems like a good idea.

    But as with all ISIS BB's look at the thickness of the bearing - it's very slim. Life expectancy? Short.

    Well, it depends on the alloy they used, but Scandium likely makes up a very small percentage of the total. What the Scandium does is refine the grain structure, making for higher strength alloys at the same weight as 6000 and 7000 series Aluminum alloys. It also makes welds stronger, by decreasing recrystallization, but that hardly seems a consideration here.
