Fork's upper tube problem

JonWk

Hi,
I have maybe a silly question, but here it comes. I bought the Leader 516 frame, and I was planning to use the fork from my old bike. Well the problem is that the diameter of the fork's upper tube is something like 1" and the hole in the frame is like 1,8". So is there anyway I can get the fork to fit the frame?

Your steerer tube is 1"?

if it is 1" then get some frame headset reducers to allow you to run a 1" headset.

but more info needed. what forks. what dis they come off etc etc....

Thank you for your answers.

Yes the steerer tube is 1", not the upper tube.

The fork is Mozo Vibe, and the length of the steerer tube is about 8".

Sounds like the fork is from the old-style headset design (which I forget the name of) that uses a wedge to lock th estem to the steerer. These have been abandoned on mountain bikes for roughly 20 years in favour of the more straightforward Ahead style headsets, where the fork's steerer tube goes right through the frame's headtube, and the stem clamps on to it at the top, also holding th epreload tension on the bearings.

Is the steerer threaded?

Are you sure it's 1"? An eigth of an inch is hard to measure. The only one I've ever seen was 1 1/8" threadless.

this worries me as the steerer is the upper tube of a fork.

Now that I measured it again, it actually is 1 1/8".

The tube which I'm talking about is the one that links with the frame. I apologise if I'm using the wrong terms.


Are you guys saying that I should now buy a new fork and a stem? And if I do, feel free to recommend manufacters and models.

well, you gave us wholly wrong information, so you can pretty much dismiss everything that's been said.

I did not say that - you'll be hearing from my lawyer.

I recommend you look around the park tools website or Sheldon brown's (both linked to in Nick's sig) so you know what you're on about next time, you're also less likley to kill yourself when at 30mph the front wheel comes off......

Is all about the headtube on the frame - identify what sort of headset it takes via Park Tools website.
