    Karate Monkey MDS: no short 431 mm chainstays any more :-(

    Surly says: chainstay length even at the new(er) Karate Monkey OPS is still 431 mm.

    I wonder how this can be

    I you use the singlespeed version, you theoretically have 431 mm - but you need a few mm to tighten the chain, so 435-438 is the shortest cs length.

    Then I tried the QR and the thru-axle version - and you get surprisingly 450 mm and 440 mm.

    Sorry Surly: never ever 431 mm

    Why did you do this?

    My last KM (non-MDS) is probably my last KM, and it's been more or less relegated to bikepacking duty. For a real MTB, I'm thinking something like a Canfield is the way to go.

    I was going to get a KM mds until I learned this. Nevermind.

    They need to update the geo chart on their website at least.

    Well, the previous 431mm chainstays were always tough to obtain in single speed mode. But yeah, it's sad about the KM losing this defining characteristic.

    At least we still have the Ogre!

    I have my OG Monkey perfectly slammed in the dropouts with a 32/20 gear ratio, so the effective CS is about 17". with a 1x9 setup, I just let the axle slide all the way into the dropouts. I don't use a front derailleur so it works fine. this is why I won't be buying a new KM unless they revise the dropouts to allow for a 17" chainstay.

    They only must make some inserts which have the axle position at 431 mm - perhaps there is an update in the future?

    Ironic, because I always thought the Ogre was the one that should have lengthened chainstays, given it's marketing as a touring bike.

    Now that I think about it what differentiates the new KM from the El Mar? And considering they are under the same umbrella...

    I liked it better when Surly made versatile bikes, rather then specializing them all.

    I sent an email about the long chainstays to Surly. I tell you, when I got an answer.

    El Mar frameset comes without a rigid fork, so when you wnt to ride rigid, you have to order it separate. Unfornatutely it is not availiable in frame colot but only in black :-(
    Steering angle of El Mar in 71, so 1 flatter tham KM, which has 72.
    KM is powdercoated, El Mar is wet paint which is not so stable.

    Fair enough, but if you were running a bike company do you think it'd be prudent to sell two bikes that were so similar under two different, competing, brand names.

    I now have an answer from Surly about this and this is indeed what the are planning to do. It takes a little time, the say "later in 2015" and in the meatime there will come an article on their blog.

    It seems that first they wanted to make possible ridig fat 2,5" tires with front derailleurs. I'm curious about the new MDS chip(s?) next year.

    if they come out with a chip that allows a 1x and a 17" chainstay like my current KM, I would buy that.

    Looked at the Surly Website and saw this:
    Small Parts | Parts and Accessories | Surly Bikes

    The 12 mm slotted MDS with derailleur mount is new, isn't it?
    So Surly listened tu us - but only for thru axle wheel - not for QR wheel.

    Is there another MDS coming?

    edit: ...even more than before, if that's even possible.
