    dw-link 2XC and the Ibis Ripley 29er

    Bet you didn't see this coming, an all new dw-link suspension layout, dw-link 2XC (or dw-2XC for short) on the brand new Ibis 29R, the Ripley. goo.gl/UEa9A

    We've been working on this bike for what seems like forever. Far before it was fashionable or even heard of to have a shock clevis, and one of the first bikes since the I-Drive and Decathlon to use any type of eccentric link. Obviously more is better so we have two of them!

    A lot more to come but I hope you enjoy it!

    Dave

    Suh-sweeeet! Not at all what I was expecting, but a pleasant surprise! Can't wait to throw a leg on it!

    The twin eccentrics - once I got over the brain ache of wondering where the link had gone, first thought was wow, kinda Yeti Switch-ish x2. Look forward to seeing video etc of it in action, and pics of a built up bike too.

    There aren't any geometry numbers on the Ripley?

    Well aint that a pretty looking big wheeler. I can't wait to see the colour options.
    The rear triangle looks like it should be nice and stiff.
    What length are the chainstays relative to BB?
    Can anyone tell me how many Ibis bikes is too many to own ;-)

    It's got a cute small butt. Some interesting bits there. The swingarm to shock link looks thin, but must be solid. Haven't got a clue about the new linkage though.

    I can tell you one thing. The chainstay length is short, shorter than most if not all. I think that people will be happy.

    W O W. I'm not in the market for a 9'er but deeezam. How techy is this sheeeeit!?!? Way beyond me but I trust the minds of Ibis and DW.

    This changes everything....wonder if the eccentrics will trickle down to future models. If it's as good as they expect, I'm betting it will.

    Dave,

    Good work. I think this could be my first 29er.

    Anyone know what sizes they will be made in as I'm currently on a small Mojo.

    Wow, even before Titus used it on the Racer X?

    I saw this and had flashbacks of my old mac-strut Racer X, although, this version does pivots vertically, the RX did not.:



    Bike looks fantastic BTW! (And it has a useable water bottle mount!!!) Between this and the new Yeti, my resistance to 29ers may crumble yet. Glad I'm not in the market for at least a year.

    wow, cool.

    So, do I understand this correctly: eccentric bearings means that the attachment to the rear triangle is located off the centerline of the bearing, but the center of the bearing passes through the main triangle (?). Putting two of them on allows the rear triangle to move in a dwlink path, without links, saving length on the linkage and freeing up the geometry for shorter stays and more clearance etc? Do I have that right?

    Not that interested in a 29er at this point, but stoked that ibis and dw remain out front in new thinking, ideas and innovation!

    How would this technology benefit future versions of the SL and HD? And when will it trickle down?

    Nice refactor Dave!

    That new linkage structure and press-fit bb must be where the rumored incoming weight drop on 2012 HDs is going to come from I would wager albeit in a more rugged design.

    Why? That makes the minimum size 160mm. You can go bigger with adapters.

    The 140mm rotor size is being phased out with the exception of disc cyclocross bikes.

    I doubt they would use the new design/technology in the 2012 HD's (not saying that I wouldn't want it). That would mean redoing the molds which is just about 2 years old. They need to recoup the costs which I doubt they could have. And even if they did.....I'm sure they would like to maximize their investment costs by leaving the HD alone (and Mojo SLR, SL) for as long as they can.

    It's one thing to come out with new iterations of the links as they did with the original Mojo but overhauling the entire frame when it's only 2 seasons old is completely different.

    Thank you Hans. Can you also tell us something about the weight of the frame and when it might be available (I know it won't be before 2012)?

    We're are going to do a real launch with frames in stock and all the rest of the info next year. We are not quoting the target weight, price or delivery date, but of course will announce it with the full launch.

    So I wonder what those two little nubbins (technical term) on the seat tube are? Grease ports? Set screws to keep the outer sleeve of the eccentric from rotating? Braze ons for a flask of Courvoisier since you're such a fly playa?

    Maybe they are to preload the bearings?

    Exactly.

    You can adjust the pre load with a 5 mm allen wrench. One of the cool things about this angular contact system is that you can take all the lash out and still not have much friction in the system.

    ripley's back...

    There must be an eccentric or two in here someplace. I'm putting my vote in for a black & yellow stripe paint job.

    I believe it is to bolt the two halves of the eccentrics (part 3 and 9) once they're installed in the frame. What I mean is part 3 and 9 would each have a half inserted into the frame from opposite sides and then bolted together.

    That's kind of a bummer...long and steep. Doesn't the steepness somewhat contradict what is typical for a 120 mm travel 29er?

    dw, any problem running an Angleset to at least bring the head angle to where it should be? When you said that the chainstays would be short, I thought you meant it as "shorter than many others" not just shorter than the longest ones out there.

    I agree. Wish it was a little slacker but if and angleset can be used then its not a big deal.
    17.5 is not too bad

    17,5" is not that long for a 29" bike. 71°ha seems to be quite common too. I've read some reviews about the Scalpel 29 with 71,2°ha and the tester quote that it felt more than 68°.
    Ok, that was with a 100m Lefty and no 120mm Fork.

    Oh, and what's the bottom bracket height. I'm guessing it may follow a similar pattern as the SLR and HD having a tallish BB.

    17.5" is long when you're used to the snappy handling of a 29er with 16-3/4" stays. The rather sluggish feel of 17.5" stays is great for those XC types who spend all their time in the saddle.

    While the Scalpel may have felt like 68...71 is 71.

    71 degrees on the 29er will be equivalent to 68.5 to 69 head tube angle on a 26" bike with the same tire height. That's why I don't talk about head angles with my partners anymore. I have them all speaking the language of "mechanical trail". 17.5 is pretty short for a 29er, at least equivalent with a few of the shortest that I know about. I'm sure someone has a list of the shortest ever and will be quick on the draw with that. I'll tell you what, it's a heck of a lot shorter than most...

    Agreed totally on your first point, although the guys coming off bikes with 18 inch chainstays (and that's a lot of them) will be stoked at that 17.5 number. It's all relative.

    To your second point, 71 is 71 for 26" bikes, 71 is 68.5 when comparing a 26" to a 29". You can't directly "feel" head tube angle, it's just a random number. What you actually feel is the effect of the measurement that we call "trail" broken down into ground trail and mechanical trail.

    Did you know that changing from a 2.1 inch tire to a 2.3 inch tire, even without any head tube angle change, has the equivalent change in handling that almost a degree of head tube angle change has? Science can be fun at times.

    Dave,

    1 - Keep dropping science on us, its awesome.

    2 - The new pivots, and the eccentric, seems really close to Yeti's new Switch. Now obviously DW link has been around a long time and Yeti's work I think is to be taken as a compliment to your engineering skills. Does Yeti's direction pay homage, and is there play back and forth in a friendly competitive way between these two designs?

    // This probably belongs in the suspension forum but since Dave is posting here I couldn't help myself. Though Yeti just came forth with their sb-95 5 inch 29er switch bike.
