    Spent some time pissing about with caliper mounts.

    As it appears to be that i have mounts for 180-180 then that's the new braking setup.
    Couldn't get the caliper to sit right with the 160 mounts and tried some spacers to align it, but no joy.
    Need some 180 rotors now.
    Did double check and upto 200m is fine on the Monkey.

    Spent the afternoon cleaning and servicing the Hope levers, really gunked up. One hose needs trimming down to cut out some damage at the cylinder. But it's looking good.
    Will most likely just stick with standard steel M4 rotors.

    That spray tan is an awesome color.

    May I suggest an upgrade though, VO Grand Cru Long Setback Seatpost MKII, Noir - Seatposts - Components.

    Nice! I may do a similar build on my KM if my Jones relegates it to commuter duty.

    Though track ends + gears + discs + fenders is an awful, awful combination...

    Your saddle looks to be very far back on its rails. This can cause them to bend or break due to the excessive leverage the position creates. That VO post has more offset then most posts and should clamp closer to the center of the rails (while maintaining the same position).

    I'm not sure the VO seatpost is long enough for a KM. It's my understanding that on an MTB you want the seatpost to extend past the top-tube/seatstay junction and the VO just isn't that long. I've got one and it's a great seatpost but not long enough for my KM.

    I'm jonesing for a b+ bike, and the km looks to be a viable candidate. Through what I'm showing as 61 pages in this thread, there's been a couple posts sporadically, but my only concern is bb height. Those of you still on the train think it's passable? My googlefu is a little weak, I haven't been able to find any data on the height rolling on b+ hoops.

    You can calculate it pretty easy:

    Radius of 650B x 3" = 372mm

    BB drop of KM = 68mm

    372 - 68 = 30.4cm BB height.....approximately (vs 30.2 for 29 x 2.1")

    Trail would be 79mm (vs 78 for 29 x 2.1")

    So, a 650B+ KM should handle just about like a stock KM. Not too shabby!

    So, like a c-hair higher than 29/2.3, according to my google. Respectable.
    As long as it's "close enough" I think I'll be good.

    I would still try to find some people who've done it, just to make sure. These numbers may not be 100% because it's all based off that tire/wheel radius which can vary. I know people have made the conversion so they are out there.

    Good eye. I haven't ridden the bike yet. I like to start with the saddle all the way back on the rails and adjust as appropriate. I'll keep that seatpost in mind.

    Thanks for the heads up. If there is a seatpost that has more offset than the VO then I haven't encountered it. I like a lot of offset, so I've been looking.

    I always question these maths, mostly because of tire pressure. I'd be interested to see how a 3" tire with 10psi compares to a 2.2" tire with 25psi under 100lb load. Static load radius, ETC.

    Anyways I have run my KMs with tires ranging from 40mm up to 2.3" and it was fine either way.

    Track ends? My KM uses the Modular Dropout System
    Works fine for me...if you don't like the style that a personal preference and no hard feelings.

    Stripped out and cleaned up, ready to rebuild, almost.

    Didn't have a spare 9spd shifter, so got a deore coming, as 9spd deore rear mechs are cheap, got one of those over the older Tiagra road mech i had spare. Some 180mm shimano rotors, couple of chains and as continental 29er tubes where 1/2 price grabbed some spares as well as the local shops are all full RRP on tubes, so stocking up, make the most of the next day shipping charge.

    Will try and rebuild the BB today and fit that, treat the inside of the frame, get the forks and headset back on and rummage around for bars and stems and posts to play with.

    Some build up dramas and cross brand standards not matching up well.

    Monks rolling running 9spd and 180-180 Hope M4's
    A lot of tweeking/fettling to do still, but Monks rideable again.

    Reshimmed the calipers for better rotor sweep over the pads, added 1.5mm shims, much better.
    Way cheaper than going full Hope again, also the new Shimano rotors are a bit lighter than the older worn Hope one i have, not sure how long they will last but at 1/3 the price of standard Hopes, really not worried

    Any idea what that rig weighs?

    Under 30lbs i expect :)
    Might pick up a travel luggage set of scales to weigh it.

    I am more used to 35-45lb bikes so this is still fairly light for me, going from v-brakes and track wheels to disc brakes and gears has added a few pounds.

    Mine as pictured eariler. Crudely weighed on bathroom scales.

    10.8kg or about 23.78lbs

    Getting down to 10kgs should be fairly easy to do with parts bin.

    Thought Surlys where ment to be heavy :)

    and KM's were meant to be SS. Get rid of those shifty bits and you've got your 10kg bike!

    Just teaSSing of course. Nice bike.

    ah crap! i just put an alfine8 on mine!!

    yeah,i guess im gonna need a new frame....maybe a mint green karate monkey frame is in my future...got all the parts i need...

    anyway... the re-ca-jiggered km,alfine8 rear,one of the original rims from the monkey and a brake rotor off my original ogre wheels on a surly ultra new front hub,and a set of surly open bars..

    We'll have to go for a road ride once my SS Cross Check is built.

    Might try fixed on the SS commuter so the new gears are staying, never had gears on the KM before........ so dirty :cool:

    Should have weighed with the v-brakes and track wheels ages ago, must have been around 20lbs then.

    I think i can drop around 500g real easy and for free, the extra 300grams may take some work, the Hope M4s and rotors are a bit of weight over v-brakes but worth when you just must slow down/stop :thumbsup:

    lol,yeah,i went total weight weanie here,put on the saddle with titanium rails,dropped 7 grams off the bike!

    I just happen to have 4xalu bolts (in red) that will swap out with the 4xsteel bolts on the Hope lever brackets.....must be at least 2grams to save there :)
  • 04-03-2016

    Gone a bit mad, got my weight weenie on.

    Hipflask/Aherene cage/bolts =171g
    If i swap from the DH spec DMR swarm stem and Wingbars to a DMR headstock stem and EA50 bars i loose another 216g
    Swapped an inner tube dropped another 100g
    If i buy a new seat clamp collar i can drop another 20 there.
    A lot of Alu stem spacers, i have a 25mm stack of carbons at 9g, so swap out, trim the steerer should drop another 50g there.
    possibly another 10g with Alu bolts i only used rough old cable outer to get the right length for the gears and have some posh Gore cables (lighter)
    Not weighed yet as drying, washed the mud and dirt off..... swapping to Conti CX tyres should get me under 10kg......maybe...... :)

    then if you replace the frame with a nice carbon job it will really be light!

    i was just busting chops...
    im thinking of getting another karate monkey frame and the mechanics at the shop were saying i should get a nice carbon fiber frame and have an actual lightweight rig but to me that just means i would have to ride it fast and then i would have to start racing and that just sounds like too much work...its supposed to be fun...not that going fast isnt fun,just not all the time...
    plus i get the satisfaction when i put in a good time that im doing it on my heavy ass steel bikes and that adds an extra savor....

    nice thing about a surly,its easy to make it your bike,unlike anyone elses...

    Sure can.

    Well, it's not welding. But you can repair it. It actually takes fewer tools to repair carbon, but a bit more intelligence than your average Harbor Freight Welder possesses.

    Serious crowd tonight :)
    After studying weights, i can drop under 10kg with what i have in the parts bin, beyond that it gets silly and spend some money.
    Might work out a DH spec weight and XC weight as i weighed all the things :)

    Yes i am bored and not going out for a day or two :)

    I've thought about investing in some wide 650B wheels so I can mount the Compass 48mm tires for street riding. Their 700c tires max out at 38mm and often come out to 35'ish mm actual width, which is narrower than I prefer.

    B+ Karate Monkey will never work. The BB might be even lower than an ECR.

    Kidding aside..I'd love to hear how it goes. Looks real nice.
  • 04-28-2016

    It did drop the bb by 3/8" from the 29 with some fairly big sneakers. But, I still had way less pedal strikes than my full suspension. Of course, I was only traveling at about half the speed too...

    I did an experiment this morning and put some 32mm Vittoria Hyper tires on my KM to see how I would like it and basically, I didn't. The bike felt twitchy and over responsive to me. I guess I like the big pneumatic trail of wide tires.

    My reference point is 40mm Schwalbe Duremes and most of my miles on the KM are on those tires. But they are slow.....at least that's my perception after riding other tires.

    I briefly rode some 50mm Marathon Supremes and the inverted tread created a "buzz" that I didn't care for.

    Next I rode some 60mm Big Apples. Those are the tires that convinced me my 40mm Duremes are slow. But, I think the 60mm BA's are too wide for my Dyad rims.

    Maybe 50mm BA's is the sweet spot for me.
