    replacement brass rods for syncros post head?

    I have a beautifull syncors rendered useles since the rod threads are stripped. I tried fitting thomsons rods but they are slightly bigger. Tried ebay etc.. Any clues? Those machined syncros posts are an icon of early nineties mtbs.

    Good job! Maybe a long shot?

    This may be a long shot but have you already contacted Syncros directly? They offer replacement parts. I'm doubtful if they have back stock from 30 years ago but maybe they can tell you the manufacture or part numbers on those seat post pieces?

    I do also recall seeing those barrel nut rods at local hardware stores like "Lowe's Hardware":

    Hope this helps some,

    I will take the pics but i can describe as well: itīs a rod thatīs insert on the top part which presses against the saddle rails and the cam. Two bolts attach on the rods.
    Thomson has similar rods but spec is slightly bigger.

    Syncros tell me i should go through their dealers but there are no syncros dealers around. I saw those barrel nuts at Lowe but there is no way to tell if the right width; those things should fit tight inside the top cam. Best bet is finding a busted Syncros post and canibalize the part.

    Do you mean this threaded rod?

    BTW, the entire saddle rail assembly from Thomson is the exact radius as Syncros and they're interchangable.

    Thomsonīs rod is slightly bigger and does not fit inside Syncros cam. I could take the whole thomson top cam but rather keeo it all syncros.

    Thomson also has hardware for their dropper post which aren't compatible with the Elite or Masterpiece post. In the pic they look like a smaller diameter. Maybe shoot them an email and see if they're close to the Syncros parts.

    I tried fitting them to the Syncros and no go. I would have to shave material and i donīt have machines to do it.

    The dimentions from bikepro's site.

    "A hole is drilled through the arms that will accommodate a brass rod. The rod is .58" long and .3" in diameter with a hole drilled through the middle of its side, tapped with threads."

    Does it list thread size by chance?

    If only Thomson used the same rods: theirs is a fraction of a milimeter bigger. Thread seems to be the same but size of the rod is different

    LOL. You had to ask. The BikePro site is deep with info.

    "The bolts are made of cadmium plated steel with 5mm x 1mm threads, are 35mm long have a 4mm hex fitting and weigh 6 grams each."

    Dang! It’s so satisfying to my machinist brain!

    BikePro either has a typo, or Syncros chose the M5x1 “special” thread, which is not very common. Most metric tap sets don’t even have that thread size. M5x.8 is the common size in 5mm.
