    2019 FourStroke ?

    Looks like a new model will come out. I wonder what they will change with the Agonist fairly close in the line-up.

    Rear Boost.
    Internal cabling.

    ? Geo ?

    I haven't seen anything yet, but I would expect something similar to the Agonist but 100mm of travel front and rear...

    Looks pretty solid, slack HTA with short offset fork, integrated dropper is neat, weight is midpack, 1 bottle cage. Love the skinwall Barzos though

    Anyone got any idea about pricing on these beasts? I'm not too convinced by the builds, but the frameset could be an interesting purchase..

    Thanks... I'm curious as to why these didn't make more of a "splash" - it seems a touch more aggressive than even the Intense Spider which is where the world seems to be headed...

    But it is in the line up for the Bible Bike Test (but of course they don't include much to compare it with, aside from the SB100...no Sniper, no Oiz)...

    Anyone seen or ridden one yet? I don't think they are supposed to be in stock in the States until February.

    A couple of test rides. Size XL 12,1kg with XTR pedals and tubes. My experience: Very long front-center with 70mm stem. Feels like a very progressive rear suspension tune. A bit harsh rear suspension probably due to below freezing temperature and being brand new. Pedals great with good flow in open mode. So good it may not need the middle setting. Crank thankfully not as low as Spark RC. Downhill nothing comes close. Climbing it is close to but not surpassing the Scalpel. Could just be the weight.

    Thanks MrRidealong. Thinking about getting off a Scalpel and getting on an FS01 for next season.
    Anyone know what the weight of the TWO and ONE come in at?
    Is the remote a 3 position? I thought all the new Fox forks and shocks were only 2 position remote.

    The bike bible has it listed at 23.5 lbs. Here is a link to their review.

    I second the question, is it the 3 position or the 2 position remote?

    MrRidealong, have you had more time on the new Fourstroke? How do you like it? Mine is at the shop on display and I won't get to ride it on the trails until April with the weather.
    I'm thinking about making a custom bracket to hold two bottles like the one in the picture. With the three bottle bosses to utilize, I think can machine a one piece aluminum angle to mount two cages. I need to get over to the shop and make some templates to see how two bottles fit in the large frame. I'll post when I get started on it.

    Almost 500km. Only cold weather riding with spikes. Rear suspension still feel very short travel/progressive. Must try shorter than 0.8 spacer. Stays high in travel. Less pedal strike. So solid downhill. Even with the 90mm stem I am testing now. Was planning 2-position lockout, but if going for softer shock tune, will probably need middle position. Dropper post has some rotational play but within acceptable limits. Will soon start building a lighter bike based on the black frameset with kashima shock. Handlebar weight is 300gr + ! Changing to Extralite stem/handlebar saved 250gr. Very soft but very light... Need to find a new headset top cover. That Lyne system looks very smart! I am using the Wolftooth system but will definetly look into that 2nd bottle cage adapter.

    I tried mocking up the two water bottles like the Lyne system on my large today and it won't work. Not enough room with the lower standover height of the new frame design. Maybe it will fit the XL?

    Would it be possible to remove the dropper and use a regular seatpost? You mentioned some rotational play... Do you notice it while seated & pedaling? When standing...do you hear any rattling in the dropper area due to the little bit of rotational play? Thanks.. I'm trying to make a decision b/w this and the agonist.

    You can't run a regular post because the oval shape.
    I haven't ridden mine yet but the seat moves ever so slightly, maybe a mm or two, back and forth. You need push on it to move it. I don't think it's enough to notice while pedaling but then again I haven't ridden mine yet.
    I've bounced the bike up and down on the rear wheel on the shop floor with no noises or rattles.
    Agonist is a really nice bike but will be a couple pounds heavier.

    Thx. I'm doing just the frameset, so I think that brings the weights a bit closer. I'm leaning 4stroke since that's my current rig 2017.

    MrRideAlong or anyone else running the non stock oval BMC stem, have you been able to come up with a headset top cap solution that looks better than just having a big hole into your frame like shown on MrRideAlong's last picture?
    I've been searching Instagram for the Team BMC pro bikes, as well as Absolute Absalon pro team bikes. Most of them are slammed, and most of them are running normal circular stems, but I haven't seen a good picture of what they do to cap the headset and make it look good.
    If anyone has come up with something, I'd love to hear/see what you've done. Thanks.

    FSA Orbit 1,5Z at bike.24 at 44 EUR. Outer dia. 55mm. Cannondale could also work but outer dia is only 54mm and you will need the one for 1 1/8 steerer. FSA is the «flattest» one I have found and requires the least amount of shims underneath. Syntace Megaspacers I got from R2.

    I also did a flat on but do not have a picture of printed version. The flat version is just the base of the tapered one that I transitioned from the stock bearing cap to a circle. I can share the CAD file if you PM me.

    Hey MrRidealong, checking in again about your headset setup. I've been able to find all the parts you used, except the 1.5mm shim that you placed between your frame and the bottom of the FSA Orbit. Can you point me to a website where you found the 1.5mm shim? All I'm finding is the 1 1/8" shims, which I don't think will be a big enough outer diameter to cover the 55mm diameter FSA headset. Thanks man, I appreciate it !!
