Bent: Kh 04' Cranks.

Evan, the red line you drew is blatantly slanted upwards... you
axle/cranks may be bent, but the pucture doesnt allow you to tell how
much.

It looks so minimal that it would be unnoticeable when riding.

I'd recommend just keep riding it. That's not very bent. 🙂

BTW, didn't you have a profile hub on your uni at one point?

If it's unnoticeable while riding then live with it... It's not gonna
make you suddenly unable to ride because you "think" you bent your
cranks...

You need to reverse your foot position when dropping and even it up 🙂

Evan described the drop to me, it was 5ft, onto slanted cement, all his
weight was on his back pedal so he wouldn't roll forward into a possibly
painfull obstacle, ten bucks says his knees were straight to make sure
the wheel didn't have any forward roll when he landed as well, I say no
wonder they got bent. I'm suprised he didn't shatter his knee. Probably
would have if the cranks didn't bend ^^

Why were you doing a 5 ft drop to asphalt on a uni other than your
trials? 🙂

Also, I thought you were too poor for profiles.

Ahh, but is the hub bent, or just the cranks? Its probally just the
cranks, or did you know that?

Do you keep your knees straight when you jump, while not ridding a
unicycle? Well its a bad idea to do it on a unicycle as well, I just
keep enough bend in my knees so they don't lock, better on your joints,
and you'll have a smoother ride, I thought you knew better then that
Evan.

Listen to me, there is a reason I rode motocross for six years and never
broke a bone. I learned how to fall, and to roll. I don't care how fast
your going down, sticking your arm out is only going to break it, keep
your body fluid and limp.

the cranks in kh hubs always have some room even if they are new. mine
looks the same. they are not bend 🙂 if it will be 30 degree ok but not
like that.

but if you want to make them strait
you can dismount the cranks nad put it again but in another position and
tight very strong. it will help.

to make a sum... dont wory its ok...

It sounds like you are not thinking this through:

1. Your photos show no evidence of bent cranks. If the cranks bent, you
would most likely see it in the form of pedals that slant toward the
ground (viewed from the front or back). Your suspected problem is a
twist in the axle. Moving the cranks around to various positions might
tell you if the twist is consistent, or if just a few splines were
affected.

2. You plan to do drops bigger than 5ft. What does this mean? Basically,
eventually it's likely you will break equipment. If you have Profiles it
is less likely, but still possible. The question is whether it's worth
it to invest in the Profiles, or have to replace parts down the road.

3. Landing a big drop on a slanted surface, with no rollout, is going to
put a lot of stress on parts (yours and the unicycle). Though there may
not have been any place to roll in that situation, you could also
consider not doing that particular drop because of its wear & tear
factor.

4. According to what I've read above, your landing technique has room
for improvement. Learning to land with less shock to the unicycle will
save you money, and be a kindness to your bones and tendons as well.

5. Yes, if your axle is truly twisted (looks likely from the pictures
and story), it is likely to twist more. Metal, once compromised, becomes
weaker. In its current state, your axle looks fine, completely rideable
and all. But it may be a little weaker if you do a similar type of drop.
Keep it up and eventually it will give way. But better technique could
stave this off by quite a bit!
