On my DS3 Gen 5 the stem is blendr compatible since it the bontrager elite 31.8mm. According to Treks blendr charts, the WS537090 duo base is supposed to fit on the stem. Unfortunately it’s not the case. I have disconnected the handle bar to install and the duo base dosent fully seat in and is actually pushing out the stem handle bar mounts. Anyone else have these issues? And any remedy or fixes???

  1. Your bike was built with the old style stem. Contact Trek or the store you got it from to explain the situation, and they may send you the correct one.

  2. I’ll have to take a picture when I get the chance, but I also had the same issue.
    Took it to my local Trek store and they ended up replacing the stem because it was not compatible with the blendr mount

  3. You have to loosen your stem bolts or take the bars off pop it on and then reinstall. I did the same thing first time I tried too.
