• Intergrated headset standards have once again got the better of me.
    Trying to figure if this headset lower will work on a Carbonda 696 (which is also an On-one Free Ranger, amongst other branded frames).
    I believe it will work but what throws me is that the headset Planet-X recommends for their frame uses a bearing 'Lower: OD:51.8MM ID:40MM 36x45', where as I'm assuming the Hope headset lower uses a 45x45 bearing.
    Am I just assuming wrong, does this matter, please help lol

  • I don't know which angle the hope one is but assuming the fork has an integrated crown race then yes it does matter that the angle is correct

  • Thanks!
    Looks like the fork does not have an intergrated race (at least not on Carbonda's own version), so I assume with the correct/matching crown race, a standard IS52/40 headset lower should work.

  • then yes it does matter that the angle is correct

    Does it though?

    I’ve bodged together a load of regular 1 1/8” press in cup and integrated type headset bearings and some 44mm and 56mm headtube stuff with whatever crown races I’ve had on hand and never had to bother measuring angles.

    Have I just gotten lucky?

    Top bearings are a different matter, the split wedge seems to sit atop some and inside others so you definitely need to get a pairing that works together.
