    Singlespeeding a softtail - will it work?

    I've been offered a Dean Duke softail secondhand, and I'm really, really tempted to get it and run it singlespeed.

    Does anyone know if it will work? Ideally I'd like to run it with SS dropouts, and therefore no chain tensioner.

    I guess I'm worried the movement at the back will cause the chain to jump off, or skip.

    Thanks all,

    Leon

    a couple of people seemed to think it needed a chain tensioner, but not many.

    Wonder if they were the only riders in bumpy areas?

    Any first hand experience?

    Yes - it works fine

    First Hand - 2000 and 2004 Dean Dukes ran as SS and it worked fine. The chain does slack slightly upon compression but not enough to do anything. I did notice more flex on the 2000 in the rear end. The rear shock was held to the chainstays with a single 6mm bolt (instead of clamping on the shock piston like they do now) and the chainstays were smaller in diameter. Needless to say, the 2000 flexed a lot more than the 2004. Of course, I weigh 200lbs so flex was an issue for me.

    Top photo is the 2000, bottom is the 2004.

    what's the magic gear? I notice those aren't SS dropouts.

    I weigh 140lbs, so I doubt flex will be an issue :-)

    I think this frame is a 2005 or 2006.

    I've got a Castellano Fango (former Ibis Ripley) Eno'd and it works fine. I used a half link to get the Eno in the "rear" position and I haven't really had problems since.

    Magic Gear

    The 2000 used 34 x 17 and it worked smooth. I ground my rear axel on one side (like a mini version of the ENO) to get it perfect.

    The 2004 sits at 32 x 18 with a perfect fit - no axel grinding. I estimate my chainstay length at 16.713". As you can see from the chart, if I want to go with a halflink and grind a few thousands off the axel - I could go 32x16.

    Here's a pic of the chart and a ground axel, not mine.

    chain length won't be affected as the chain stay is pivoting from the BB. Only where the pivot point is removed from the BB do you get a change in BB to Hub distance. Unless the sus set up is a unified rear triangle.

    I did think that, but I was wondering if there'd be enough side-to-side flex to knock the chain off. It seems not though.

    Thanks for the replies guys.
