    Bought Cube acid 2018 but 27.5 is it bad ?(feel so regret)

    Hi , i just bought brand new 27.5 18 frame cube acid 2018 but i see now 27.5 not good for hardtail.i feel so regret. I dont open the box, yet so i am thinking about sale or open box and ride and just fun. Is it optimistic or just sale 27.5 and buy 29er?Whats your opinion.Is 27.5 very bad compare to the 29er on the same bike how many percent difference is there between 27.5 and 29.

    Also I am 178cm(5'10) and inseam 78-80cm(31.5inch) cube acid is medium frame(18) , is it small for me

    Talk to the seller about getting a 29 in exchange now while the bike is unopened. Also get the correct size in whatever you end up with.
    27.5+/29 hardtails give you more tire width options going into the future than a straight 27.5.
    I wouldn't buy new without Boost sizing in the frame(12x148) and fork(15x110) to be able to use 2.5 and wider tires when I wanted to try them.

    Thanks for reply.
    I bought the bike while traveling abroad 1-2 month ago now and my own country so i cant not return the product or exchange
    i dont open the box because I planned to ride the bike in the summer and summer almost came.i just checked size from bike-discount site before buying it say
    Crotch height: 78-80
    Frame height: 18 inch corresponds 46 cm

    27.5 wheel dramaticly bad compare to 29er or there is a difference of 10-15% between them.I wacthed almost all 27.5 vs 29er compare videos and forum posts No one buy 27.5 hardtail unless short but i did experience... i do not buy never any 27.5 650b wheel.

    Sell it.
    You may as well assemble it a test ride it.
    Sizing depends on your inseam measurement in shoes plus your height with added consideration for your arm length if it's abnormal. Use a book against a wall to help you measure inseam distance. That model has a short cockpit reach measurement so a Large is likely your size unless you have long legs for your height.

    Ride the bike, itís in the ballpark for sizing, I do believe. 29ers are ok, but Iíd ride a 27.5 anyday. 29 is not the holy grail. Thereís tons of folks that love the 27.5.

    The smaller wheels accelerate faster, and they are more maneuverable. If you are riding technical terrain the 27.5 wheels will give you an advantage in terms of line picking and quick changes of direction.

    If you are dead set on bigger wheels, you might try a 29" wheel up front with a short fork. I'd go with a rigid fork if you went that route, but a suspension fork would work as well. The shorter the axle-to-crown distance on the fork, the less the geometry will be changed and you will benefit from some of advantages of a 29 inch front wheel.

    The steering will slow down a bit if you go with a smaller back wheel/bigger front wheel, but you get used it, and the increased rollover is nice.

    The Reach numbers are showing as low. That can give you a tight cockpit. Or require a long stem.
    An example is a Kona Honzo. S M L XL. Reach is 425mm 450 475 and 510mm.

    You'd be a M in the Honzo.

    The bike is in a box. Sell it. Get what you can for it and make a better choice going forward.

    My buddy bought a Chromag 275er hardtail and he loves it. I don't think you have to have a 29er for a hardtail.
    Safe riding,

    Meh, just go ride it. People are still having the time of their lives riding 26ers and that bike is a perfectly good MTB as far as hardtails on that price category go. Besides I don't think you will get significantly more money selling it as new in box vs. slightly used.

    Who cares about wheels size, it's pointless to worry about unless your an experienced rider that knows what they need for their specific riding.

    But ordering a bike not knowing what your proper fit is was a very big mistake. Never buy a bike online under you have a solid understanding of how geometry will fit you and what size you should be riding.
