    Softride beam torque value for height adjustment nut/bolt

    Hello, I just purchased a Burley Duet tandem that has a Softride beam for the stoker. I have failed to find in my searches the proper torque value for the Softride beam height adjustment bolt/nut. Thanks in advance for your help.
    Mark
    PS Would anyone also know the proper torque for the fasteners holding the seat clamp assembly to the Softride beam? There are three fasteners. Two smaller ones at the lower edge of the clamp and one large one that secures the seat rails to the clamp. I do not want to over tighten and risk damaging the carbon fiber beam. Thanks again.

    You can look at Softride.com for some of their specs, but I don't think they have torque listings. We no longer have a Softride, as our Burley eventually broke at the point of beam attachment, the pivot spot. Long story, probably won't happen to you. We had it set as high as we could get it for tall stoker.

    I always tightened the slide at the frame pivot as tight as I could get it, and never had problems just tightening the factory seat bracket till the saddle was secure.

    If all else fails, the owner of R+E Cycles in Seattle was using a soft-ride on his primary tandem up until two years ago. No doubt he'll have the answer to your questions if you contact the shop.

    Thanks for the replies, I did find excellent info at the softride site for installation, maintenance, and part numbers. But nothing about torque values for the classic beam. For the height adjustment bolt they recommended after adjusting to the proper height to "tighten securely". As for the seat clamp system I could find nothing. Monoborracho, I like your suggestion of tightening the seat bracket till the saddle is secure. My concern is I do not know how delicate or durable the beam is.
    B. Carfree, I will give R and E a call.

    Never heard of an issue with the Softride beam. Attachnments point on a retrofit on a C'dale broke.
    Owned Softride single plus rode a few hundred test miles on a Burley Softride equipped tandem.
    A great system; preferred to any other rear suspension setup.
    'Tighten securely' is the best you can do.
    Just our input/experience.

    The beam is durable. Not to worry. And FYI, Zonatandem remarked here when it happened that ours was the first time he had ever heard of a Burley frame failure, and he has forgotten more about tandems than most of us know. Probably can find my thread somewhere her about the last ride of our Burley. All the best.

    The beam adjuster has tapered wedges that force tighter when downward pressure is on the beam. Snug with a short Allen wrench is all you need. About same torque as a seat post binder. If you crank down too much you can easily damage things. If you do not have it tight enough you will know immediately as soon as you ride it, but we have never had it be too lose. It takes a lot less torque than your instinct tells you...

    This is really important because if you crank down with the force you think is right you will strip it. It is a really smart system with the tapers that tighten with load, but if you do not know about it you are in trouble. Also be careful when installing that you have the wedges the right way.

    Our experience with our Softride was much different. It was our first tandem and took a while to get it dialed in for 33" inseam stoker and it slipped as often as not after adjusting. Eventually we wound up with the highest setting and I bought (I think) the last extra long "seat post" for stoker. So we had a bit more torque than most folks. One morning while riding stoker complained about a different feeling on the beam. Stopped to look and it was cracked across the downtube in front of the pivot point where the tube began to curve.

    And so the Burley died.

    Ugh. Ours on our CoMotion tandem has been without a problem at all, though I ride with my 120 pound son as stoker.
