    according the bad picture it seems that the 11-38 cassette is available in 10 and 11spd (?!) for MTB.
    Would be a good alternative for dual chainring in mountains and 29ers

    Due to the derailleur shape I wonder if this will be electric?

    There's so much torque already on a 36T cog that many freehubs can't take it, a 38T cog that is that lacey looks like a good candidate for folding over under load and blowing up freehubs.

    Well it is true if you use it with 22T granny ring up front.
    If you use same gear ratio the torque on freehub will be the same. Torque is equal if you use 22-22 ring combination or 38-38t. The force that chain is pulling the freehub to the front will be ~2 times weaker on 38-38t combination than on 22-22t. It means less strain on freehub.

    A chain that accomodates a 38T cog will be pretty loose on the 14T. I hate chain clatter and skipping.

    Right, they'll need 38T-specific chains.

    For me,cassette like this doesn't make any sense. Gear 22x38 will be useless

    I think the point is to give use to a single up front. as in 1x10 not 3x10
    RAH!

    I think you're right. Maybe that's the next bike trend.

    Compared to 1x10 with a 36 or 38T cog, two rings with a 34T cassette provides more gear range, better chainline, and more consistent chain tension while allowing use of a short cage derailleur. The only arguement I see for 1 ring with a huge range cassette is simplification for people who can't properly operate multiple chainrings.

    This is the weight weenie forum, isn't it? Couldn't another argument be to remove the weight of the front shifting apparatus? That doesn't seem hard to understand.

    I think this falls in the catagory of weight loss at the cost of performance. Since you need to use a longer chain and derailleur, chain guide, and huge cogs the weight loss isn't that great.

    How much weight loss is enough to pursue? People go after a few grams here.

    You are also largely mistaken on those points. You will need less than 5 grams of extra chain, the derailleur will be the same or lighter than one used in any double config, a chain guide is optional but will weigh less than the derailleur it replaces, the front shifter and cable disappear, and those "huge" cogs are barely larger than the ones they replace and are quite light by all appearances. Talk about gross exaggeration...you do realize that people run 1x configs because they are lighter, right?

    I'd go back to claiming the chain will go slack on the 14T, at least then you wouldn't be attacking the very foundation of the forum you are posting in.

    i went to 1 by 9 at the end of last season because i would rarely pop into my 27t ring. only used it for select climbs so i felt like it slowed me down going from 2nd to 1st for a climb then back to 2nd right after. so i went to a 34t rotor ring on a 11-34 cassette and loved it.
    now ill be on 35x11-36 mathematically i get a huge range still.

    my chainguide is 17g, my derailleur was something like 109g
    RAH!

    Not if you use it 1x10. Front 32 - 36 will put less torque on it then 32t cassette can when used with a 22t granny.

    Really nice setup for 1x10, shame about the price.

    Huh? It does not make any sense. As long as your derailleur has enough capacity - whats the difference if you have 38 in front or in the rear?
