Last time on Tech Tuesday,
Ben and I took a look at a rear wheel that had turned to mush, or detensioned.
This week, we'll show you two more wheel problems you might encounter, and how to fix them.
If that rear wheel was badly tensioned, we also should check the front one.
Let's give it a spin - and sure enough, it's got an issue.
We'll just get our temporary indicator down there - like a finger
and we can see it's moving away from this side, the rotor side
We check out these spokes
sure enough, this one is really loose.
This makes sense - it's moving that direction, if we gain tension here, it'll draw it back to center.
So here again we see a problem of spoke tension.
Simply doing this is probably going to fix it and we're good to go.
What do we have here?
Let's see what the TS-2.2 holds for us, Ben.
Pretty ugly.
if this is a lateral problem like we saw before, it's easily fixed.
So we simply find where deviates
Right here we can see this deviation.
it's moving toward the cog side. - Easy fix.
- So here I'm going to find my loose spokes opposite and tighten those -
except these are really tight!
- That's a bad sign. - This is not looking pretty.
My loose spokes are on the side that it's moving to.
This metal has been... - It's been bent.
The hoop is deformed. This isn't just spoke tension.
This thing needs to be re-bent if it's bad enough in the field.
How are we going to re-bend this?
- You could beat it on something, can't you?
- Well, we could beat it on mother earth. Good idea?
Hard to control.
We're going to do some controlled bending
but first we have to look for just the right tool. what are we surrounded by?
- Trees? - Let's go find the right tree.
This tree might do.
We're looking for trunks that are pretty much vertical and a place to jam the wheel.
what we want to do is pry back the section that's pulled over.
So that was right here.
So I'm actually going to loosen several turns on these spokes
because we don't want just to pry to even -
we actually need to go past where we think we're even and then regain tension.
So here we're going to jam it in the tree... there we are.
So we're supporting here and here - this is the section
We're going to go a little bit... I want a little bit of deformity...
Stop
we're going to regain our tension and then we're going to give it a spin
and see if we made any ground.
Let's have a look and see if we made any progress.
It's better... it ain't pretty, it's not perfect
It did not unbend the metal - it is basically stretched
It's still best to get this rim replaced but that's going to get us home.
Let's get this wheel out of here.
Ben, I want you to find a rider for this wheel!
Next time on Tech Tuesday
Oh, that looks terrible.
