    Is ACC running a prototype?

    ACC posted a pic on instagram today of a bike that could possibly be the replacement for the current mojo/HDR. At least it doesn't match any of the current Ibis FS frames

    So, is this the new HDR?

    I don't do instagram, but I follow her on Facebook. This picture clearly differs in style from the rather simple shots she usually posts. Coincidence?

    Good eye! Looks like it might have the same type of link driving the shock as a Ripley...hard to tell w the mud. Definitely a Mojo-ish X front tri though, and dropper routing below or through the TT.

    Hmm, Looks like something new to me! Hard to see because of mud, but looks like a HD style front with a Ripley style rear end. I think I can almost see where the shock clevis connects to the seat stays just like the Ripley.....

    Hmm this is something new, and look at that fork. Can that be 170mm of travel? Or even 180?

    I think it's closer to 150mm, maybe the new deville AM 150. My guess is that this bike will come in somewhere between the HD and the mojo. Maybe 150mm travel with 650b, and 67 HA with a 150mm fork. And of course the possibility to run up to 170mm Fox 36.

    it is definately a new frame. and where is the rear brake line running? looks like internal through the top tube and then down to the bottom of the rear triangle (next to the dropper cable coming from the down tube then up to the seat post).

    I hope you are right. But the fork looks longer than 150mm to me.

    Yep looks more like 160-170 to me as well. I had heard rumors we were going to be seeing spy shots soon.

    A Nomad/Mach 6 competitor would make a lot of sense.

    If they were able to do the Ripley hidden eccentric with that much travel and better cable routing, I think we'll have a winner on our hands.

    Yeah, I tried to get just a vague confirmation of the rumors, and they did a good job of convincing me that the tranny was the big news for this year. Crafty
    Can't wait to see more of it!

    Is that a lower link rear pivot visible just behind the crank arm? Looks more like a link than an eccentric to me.

    I agree, I also remember Scott saying that you can't make longer travel bikes with the eccentrics, since they only give a limited amount of movement. I'm still hoping for a 150mm 650b with up to 170mm fork. Short stays are on the wishlist to.

    I also think that you can't meet the stiffness requirements of an HD[R] replacement with eccentrics mounted so close to one another in the seat tube and on the swingarm. A good portion of the lateral and twisting stiffness comes from the distance between links on the HD[R] and Mojo [SL[-R]] bikes.

    This spring there were also rumors of a longer travel Ripley in the works. The back end of that frame looks more Ripley than HDR to me.

    I really really don't think that is a 29" fork.

    With the lighting, it's hard to say but those wheels look like the Mavic enduros with the yellow rim. Those come in 26" and 27.5".

    They're definitely Mavic wheels of some kind, you can tell from the fat aluminum spokes and unique nipples. Mavic doesn't make 29ers with yellow rims that I'm aware of (could be prototypes?)

    Interesting that the bike appears to be running a non-stealth dropper. The Ripley's eccentrics require a non-stealth dropper, while nearly all other current frames are stealth. Makes me wonder if this bike has an eccentric... I bet you could get a long-travel eccentric DW if you used 1.5" headset bearings....

    With the basic Ripley frame, maybe they have created a "Ripley HDR" with 27.5, links instead of eccentrics, and added in 35-40mm of travel?

    the front does look Mojo-like. Luckily, because that's such a beautiful design, I think it should be kept. Also, the Crossmax Enduro wheelset doesn't exist in 29, luckily. So, it should be 27,5.

    Doesn't the front shock mount look more Mojo than Ripley from that photo, though?

    Seems like a Ripley shock yoke on an HDR+ swingarm and HDR+ front end. The lower link looks pretty similar to HD at that angle. At least some of the speculation of an upcoming Ripley HD was based on the yet-to-be-released 941 rims-- at the time (several months ago), the logic was 'why would 29 rims be that massive unless a Ripley HD was on the way'. But given the (now but not then obvious) broad use of 941, support for Ripley HD speculation /may be/ diminished. 650b HD+ is consistent with acc's previous ?tweet? about a WC capable Ibis frame on the way.

    But if it IS a Ripley-like shock yolk we're seeing, that would argue for an eccentric bike of some kind I think; same with external dropper routing. All the link-base DW bikes from Ibis and others have a direct seat stay-link-shock linkage. The clevis/yolk setup on the Ripley is needed because the eccentrics are close together and low in the frame, so you need a dedicated linkage (the yolk) to activate the shock....

    Speculation is fun! Pivot Mach 6 also uses a "wrap around the seat tube shock yoke" and has no eccentrics. We just do not see enough of the frame and of the seat tube area to make a good call.

    True! Though the M6 yolk is a thin aluminum thing that attaches to the upper link directly. Hard to tell whether the "yolk" is like that, or a hollow CF item like the Ripley. I'd be interested in a 160mm HDR+ with M6-style DW!

    Looks like a longer travel BOS Deville AM fork, the new150mm also the BOS Kirk shock, sounds like a 150mm 650B bike.

    Could also be the 160mm Deville, i just saw they have a white version so possibly 160mm HDR?

    Agreed it looks like a updated Mojo HD with a touch of Ripley with a possible Pivot M6 style rear shock mount.

    I don't think the Ripley style clevis shock yoke has anything to do with links vs eccentrics... it's more about ditching the shock eye bushings that can hurt small bump sensitivity.... but I could be wrong.

    ...and for a little more rank unsupported e-pinion... I'll go out on a limb and say, No F'n way ACC is riding a 29er

    Yeah, good point. The more I look at the pic, the more I'm thinking new 27.5 HDR. Looks burly. That said, I wonder if this could be a hacked together test mule mating a Ripley style concentric rear with a HDR front. Time will tell.

    I went out to my Pivot Mach 6 with a 160mm BOS Deville to try and get a similar angle and stir up more e-speculation. Didn't exactly nail it but pretty close.

    I think that's definitely the same fork that I have (open bath Deville, not the new 150mm) on my Pivot (previously HD owner).

    My money's on 150mm rear, 27.5 wheels, with a completely new name.

    Either way, great to see that something's in the works.

    I had read somewhere (I /think/ written by Ibis) and it seems sensible that the intent of the vertically oriented rear shock bolt is to relieve off-axis stresses within the shock which occur when the frame is flexed laterally. This arrangement forces the yoke to also pivot vertically at the RT attachment since the RT trajectory is constrained by the DW relation built into the eccentrics. I wish I could argue this aids small bump compliance while riding critically, but I still need to order a Ripley to find out.

    A brilliant move, thank you! I still think that the fork in the spy picture is longer than 160mm.

    Since Dave Weagle does the suspension for Ibis and Pivot, there ist a big chance that the mechanics of the new Ibis follow the lines of the Mach 6.

    That does make sense, though I think the clevis arrangement on the Ripley is mandated by the suspension layout and eccentrics. The yolk/clevis on the Mach6 is a different beast, as it's actually attached to the upper pivot slightly behind the RT/pivot connection. I believe it's part of tuning the spring ratio of the suspension, and it seems to work as the M6 is the best-performing DW bike I've ever ridden.

    There'll be a EWS round in Colorado at the end of July. Surely better photos will come out then and I'll get to see it up close since I practiced with ACC a lot last year.

    While it looks a lot different from the concept they presented at trade shows, I'm confident it's still gonna blow minds.

    That is a good point, the Ripley yoke/RT angle changes from ~9.5 deg (extended) to ~20.3 deg (compressed), giving about a 5.2% change in shock force gain when compressed. That gain will definitely soften up the deeper range of the shock.

    The DW on the Mach 6 must be a lot different in feel from the (old) Mach 4 and 5.7s. Too much platform in the 5.7 and it got hung up too easily on repeated square edged hits.
