    deda 29'er chainstays, new vs. old
    was it Walt that posted the pic comparing the new chainstays with the old ones? Don't remember the thread.

    Joe B says he isn't going to have the new ones back in stock until February, but he has some of the old ones. I am building a frame with a little bit longer rear end, and I just want to reassure myself that I will be happy with the old style.

    I haven't used the new shape, but I've used at least 25 pairs of the old ....they had the best out of the box bend going for awhile.
    Don't know what you need to make you happy, but I can tell you you can get plenty of clearance for a 2.1" tire with the factory bends if you keep them longer than 435-440.

    Edit:we're talking about the S bend stays, right?

    yes, S-bend. Someone posted a picture, I can't remember where/what thread

    Here it is again. The "old" style will work (for me, for ~70mm of tire clearance) down to about 42cm length on a 29er. To go shorter than that with lots of tire clearance the new style is better but requires chainline shenanigans.

    I got mine from Ceeway back in july, but I didn't know that they were the "new" style. I ordered just 29er Deda stays.

    Walt, what do you think is there need for the chainline shenanigans with XX1 156q 32t cranks and 425mm chainstay length?

    Depends
    You should draw it up, and then you should model it with the real parts in hand to make sure your drawing is right, because I'm not looking over your shoulder so I can't tell you if what you're planning will work or not.

    The XX1 is 47.5 chainline, which is a little on the narrow side by modern (ie Shimano 50mm) standards, so depending on how much tire clearance you want, you may need to move things around. Off the top of my head I would say that 425mm is fine with decent tire clearance and enough room for the ring with either the newer or older Deda stays, but you should trust your own drawing/thinking/work, not my guesses.

    Hey walt, those look different. Is the bendier one the newer one?

    new style is bendier.

    Thanks for the picture Walt.

    Thanks Walt.

    I will definitely draw it up once I get the crankset.

    How these seatstays look, is there any updates from the older models?

    Only problem I've seen with the old style is length. From the center of the tire bend to the dropout they're a little short. Fine if your using a plate style dropout. But if your using hooded breezer style drop they come up short.

    I have never used any pre-bent seatstays so I can't tell you anything about them.

    New Nova 29er Stays
    Sorry to hijack the thread, but since we're on the topic of new versus old chainstays, has anyone picked up a pair of the new Nova 29er s-bend chainstays? I'm about the crimp the hell out of a pair of the old style s-bends to get the clearance I need for a 2.3" 29er at 430mm.

    NOVA MTB 29er S-BEND 24mm OVAL x 465mm :: S-BEND :: MTB CHAINSTAYS :: CHAINSTAYS :: TUBES STEEL :: Nova Cycles Supply Inc.

    They clearly moved the bend and lengthened the stays, but they still don't look anywhere near as curvy as other brands. I'm going to call and get the specs, but does anyone have an opinion on these? I'm making an order with Nova soon and I'm trying to decide whether to wait for a new pair of stays to come in for my current build.

    How about a drawing?
    Does anyone have CAD work for the Deda stays a photo is nice but what are the actual specs for the stays?

    FYI I just talked to Joe B, he's got the Deddiccaiccai 9er Sero Uno stuff back in stock.

    That phone call might be the high point of things for a few days.

    Don't know where you got that, but it is much appreciated. My download only has dimensions on the side view; none on the all-important top view.

    I ordered a pair from Joe over the phone a couple days ago. I hardly had to tell him what I wanted. He must be selling a boatload of these. And since I'm in Golden CO and he'll be at NAHBS next week, he "threatened" me if I don't pay the invoice promptly. What a character. I'll be at NAHBS, so I'll make a point of stopping at the Columbus booth to meet him. Maybe even drop off the check in person.

    I ordered a few pairs. No threats though. I don't think I'm alone in my surprise at Joe's appearance after talking to him on the phone.

    The bend is great
    They are a lot of fun. 29er with 400mm chainstays (nickname "Stupidmobile") that I made for myself recently with these stays:
