    Jekyll 800 29er swing arm

    Curious if there is such a thing for a jekyll 800. I'd like to transition to a 29er without buying a new/used bike. I love this thing.

    Thanks

    Nope.

    Call 'em and tell them to pull their heads out of their collective design department butts and get on it though.....

    Till then, one can only dream.....

    Duncan, would you mind measuring the opening of the frame pivot point of the swing arm? If it is larger, i'll shim it. Stupid question. Those are 29er wheels, right?

    I have a prophet swing arm laying around, so I can give you those measurements.

    The opening of the swing arm is 2 1/4 inches and the space between the bearings is about 2 3/8 inches. I hope that's what you were looking for.

    I know but these days nothing is certain just as you don't see.. well ever a SuperV 29er. I called cannondale and on top of them being very unhelpfull, not even finishing the explanation what I am trying to do I got a quick response that "swingarms are not interchangable". Cannondale!!!!... you want to change that answer?

    Very much like the jekyll. It would make a great 29er. I think.
    Thanks much for the measurements. When i get home i'll be taking her apart.

    Duncan, is the swingarm you have the same as you have on your bike? Any chance you might sell it?
    thanks.

    I think you are confusing me with Mendon who has the Super V 29er. Anyway to your question, my swing arm is almost the same, but it has a 12mm thru axle. I don't think I will sell it, because I'm looking to find it a Prophet front triangle. Sorry. Keep an eye out on ebay for them, there's been a couple up for auction lately.

    Are you talking about custom pivot spacers? If so, any hope of getting one made/ordered from you? Regardless, thanks.

    Yep, sure is!

    For the education of any interested, this is a long time project, and currently sits in the back room, awaiting more time, money and effort.

    The bearings are unique, as the OD of the Prophet arm ones is larger than a Super V's, and the pivot pin, smaller than the Prophet, so the ID wasn't right either.

    As Tony alluded to, I needed custom spacers to take up the extra room between the mount points.

    Big problem is that it has no way to mount a front derailleur. Since the bike BEGS to have the crap ridden out of it (which I did), it created several episodes of chain drop, a PITA for sure, so I back roomed it for the time being.

    The answer lies in have either an E Type tab welded on, or ISCG tabs, which would allow use of a Hammerschmidt. I like the second idea better, the first is cheaper, and both require a major amount of effort as the whole frame would have to be re annealed after welding.

    But, it's proof of concept. You can have a full suspension 29er, with Cannondale on the downtube, and the world still spins forward

    And yes, the big "29 Inches" on the tires, sorta removes any doubt as to wheel size
