# Video: How To Stop Casing Jumps - How NOT to Bike with Ben Cathro

Aug 1, 2024

Casing a jump is a rite of passage, a signal of progression, and an audible sign of a serious miscalculation in mountain biking. Anyone who has attempted a jump with a defined landing spot will have, at some point, landed short of the ideal. Fortunately, it's not an official crime against humanity yet, but there's always a risk of getting sued for embarrassment. So, let's dive into understanding why it happens and how to avoid it.

What is Casing a Jump?

The term "casing" comes from motocross. When a motocross rider comes up short on a jump, they often slam the crankcase of their machine into the ground, transferring a lot of force through the bike and directly into the rider. Mountain bikers adopted this term, and now it describes any instance of coming up short on jumps.

There are several types of casing:

Back Wheel Case: Only the rear wheel hits the landing edge.
50/50 Case: Both wheels hit the landing edge simultaneously.
Nose Case: The front wheel hits the landing edge first.
Chainring or BB Case: The chainring or bottom bracket hits the landing.
Upslope Case: Landing on the uphill part of the transition.

The Physics of Casing

All forms of casing boil down to two primary causes: misjudgment in speed or trajectory, or both.

Speed and Trajectory
A jump acts as an energy converter, transforming some of your horizontal momentum into vertical lift. If everything goes well, this lofts the bike and rider into the air. Once airborne, the bike and rider system are classified as a projectile. To calculate the correct trajectory (assuming no air resistance), you can use physics equations.

For example, if you hit a jump with a takeoff angle of 30 degrees and the landing is 3.8 horizontal meters and 0.5 vertical meters away, you need to be moving at about 5 m/s to make the landing. Factors like headwinds, tailwinds, or soft takeoffs can affect the required speed.

Misjudgment of Speed
Misjudging speed can lead to either undershooting or overshooting the landing. A headwind or soft takeoff can decelerate you, causing you to land short. Conversely, a tailwind or hard takeoff can increase your speed, causing you to overshoot.

Misjudgment of Trajectory
Technique plays a crucial role in controlling your trajectory. Popping off the takeoff too much increases your angle, while absorbing it too much decreases your angle. Both scenarios can result in casing the jump.

Solutions to Avoid Casing

1. Speed Judgement:
• Start with smaller, mellow tabletop jumps to build your confidence and experience in judging speed.
• Gradually increase your speed as you become more comfortable and proficient.

• Follow a rider with similar weight and bike setup to gauge the correct speed.
• If following isn't possible, ask experienced riders for their gearing and brake release points.

3. Improve Technique:
• Work on your jumping technique to better control your trajectory.
• Ensure you're not absorbing too much or popping off too much.

Practical Tips

• If you face a big gap jump that you can't gradually build up speed for, ensure you have a solid bike, potentially with a rearward axle path, to absorb the impact of slight cases.
• For solo speed judgment, build up your experience safely on smaller jumps and gradually progress to larger ones.
• In windy conditions, be mindful of headwinds and tailwinds, as they significantly affect your speed and trajectory.

By improving your jumping technique, following reliable riders, and practicing consistently, you can avoid casing jumps. Start on smaller jumps, pay attention to your speed and trajectory, and gradually build your skills. This approach will help you land smoothly and confidently, turning rough landings into successful jumps. With these tips in mind, you should be able to take your riding to the next level. Happy riding!

Lol, Deviate knows where the money is... Angling for a slice of the jump-casing market

Super rearward axle bikes are the best I've ever experienced for coming up short on jumps or kind of sending a bike into garbage not being sure where you're going to land - single pivot or not.

came here to see if someone honed in on the subtle product placement. got em. I can say from personal experience that I've cased the crap out of all of my local hits on both rearward axle and conventional bikes, and it pretty much feel exactly the same.

I can vouch for it... have a few unreliable jump trails near my home, I've had some rough cases and massive hucks. About a 25 foot gap, super steep lip, handled the case like a champ. Vice versa, I've had some massive hucks, almost 15 feet to flat, and it handed it amazing.

Cathro and Deviate. Probably one of the best scottish pair we've found so far. Thanks Ben. Loving your edits.

"Going a little faster than required with a mellow pop is better is slightly better than going slow and popping up higher in the air". It's good, but you can combine the best of both worlds; come in faster AND pop up higher... instant hero points and a helicopter ride too if you really commit...

I find that when I try to go faster, for the bigger jumps, my timing gets thrown off and I compress the bike too late…

@j-p-i: In Kranked 5 (I think?) he comes up about 50 feet short on a snowy gravel pit huck. Last clip is the only one I could find of it online: www.pinkbike.com/video/1253

But the editor of that clip needs to find someone with ears to pick music.

1. Stop trying to be cool and skidding into the corner before 2. Stop being a weenie and grabbing brakes on the face 3. Stop being a weenie and squashing the lip 4. Stop being afraid of overshooting 5. Stop being afraid of casing 6. Case anyway

Does anyone ride bad better? Full commitment to the case at the end.
• 5 3
find some kerbs or ledges and learn to manual for a short distance and then pop out into a hop but don't do the crazy tuck and shove. push legs out and land like a safety pencil or back into a manny ! helps with fear of looping out and getting the pop right

Love Cathro's dedication to casing so many jumps... But the one thing missing from the video is him two wheel drifting through a turn then pedalling in 14th gear and over shooting a jump all the way to flat.

Great vid, although he did forget to mention that not only does the bike help.... getting it custom painted also makes it 10% less likely to case.... its science I promise....

Funny how the second example of a case used my stolen bike. Tried to get it back but never could. Looks like the kid using it got a lot of use out of it lol.

So does Cathro now ride for Deviate? And is he riding an XL Claymore?

Hi Alex. He’s on an XL Highlander II here which has 145mm travel vs 165mm for the Claymore.

@deviatecycles: Highlander II sucked - the first movie is great, but that sequel was a travesty. Speaking of, you need to name a bike "The Kurgan", though only old farts will understand.
• 8 1
@duncanstrohnd: What second movie? You must be dreaming there were no sequels to Highlander, there can be only one.....

The Kurgan is an amazing idea and would make a great bike name.... It's better to burn out than to fade away!

God I'm old, I saw Highlander in the theater.

I thought "casing a jump" meant inspecting it before jumping, as is used in slang, "Casing a joint".

The "getting sued" thing obviously came out of the "you must be a lawyer with all those cases" joke.

Except, I've never ever heard anyone actually trying to even pretend that the "you'll get a court case against you for smashing those jumps" was ever the actual origin.
