Granted it's BMX so there's no suspension to deal with, but wow!

I can't scrub for anything, but I am tall so I've always just used my height to stay as low as possible. This takes it to a completely different level.

Pretty rad. I feel like that is basically the technique that McGrath did. He didn't really scrub but he still was able to keep the bike low.

Randomly, I can remember being at a local practice night years ago(the old Switchback layout under the lights, for PA ppl) and going through the 6 pack by the bleachers. Hepler was there on his YZ250 and he passed me over the middle double and my wheels were like where his helmet was. He didn't tilt the bike to scrub but just used his lower body to keep the bike moving forward and not rainbowing as much as I was. Pretty cool.

Amazing skills. FWIW, his pace also absolutely smoked that truck in the background

Holy cow that makes me feel old. I can't even manual (BMX) anymore without either doing nothing, or ending up on my ass.

That is amazing.. right up there with the other Lapucci vid recently shared. I am not sure what took more skill/balls. Thank you for sharing Cool

It’s called speed jumping. Basically pushing the front through the jump face and using your speed to carry you through.

McGrath was great at it.

But clearly this slow-motion shows that if the rider is rhythmically skilled enough, the jump face is not touched at all

I can stay low...I haven't found a double yet that I couldn't turn into two singles.

Justin Buckelew was very good at this before the scrub was popular. He teaches this to his students as well.

Wow those riders are Great. I would rather see the pro Mx guys do that. I think some of the Mx scrubs, are over kill on some jumps. Disrupts chassis too much,

We used to call absorbing.. which of course turned into 'zorb' or 'zorbing' haha

The technique is basically the opposite of seat bouncing. The idea is that at the instant you leave the jump, you want the trajectory of your body to be as horizontal as possible. The CofM path of the bike and rider together is the weighted vector addition of each of their paths. So you manipulate your body to create a horizontal vector for it. This much harder to do on the bike, because it weighs so much more. But still a great illustration of the physics.

Oh crap, don't go there with the physics. Apparently there is no such thing as a seat bounce.

What if you weigh more than the bike??
Does that change anything?

Might be a dumb question but I’m not exactly the sharpest tool..

I had a friend who jumped bmx bike. He was pretty good, but amazing at dropping front so deep between jumps, like what? Also, Pourcel was great at keeping bike so low, but not necessarily 'whipping' it flat to do so.

this was the riding upgrade that made MC the king of supercross.....
the fastest way form A to B is a straigth line, so the lower you jump, the fastest you get from the face to the landing of the jump, and the fastest you can put the power back to the ground.....
in the face of a jump the suspension compresses by gravity, if the rider can take his weight off the pegs at the exact time before take off, the suspension will loose some compression, there for the rebound at take off will be a lot less, not sending the bike so high, the spring efect !!!!!
MC understood well the fisics involved on jumping a moto from his bmx background, he mastered it and it gave him a huge advantage in supercross where it is all about jumps, it was usual to see MC look up when passing riders in the air...
the bubba scrub is the 2.0 upgrade on jumping low.....

Haha was gonna say that looks like fun until I saw that girl get plowed at about 40 secs in haha

(Yes I know that 'plowed' could mean something different but when you see it you know it's the only word that fits properly haha)

Musquin on the 250f at vegas supercross one year was somethin else to watch too. Dude was just in sync with the bike and the track. Looked very BMX style.

Almost every rider at B or higher level uses the McGrath style jump face soak up still all throughout their riding. The guys in the 90s paired it with the slight gyro effect which eventually lead to Bubba inventing the scrub.

Scrubs are totally more effective when able to be used but not every jump calls for an aggressive scrub hence why some pros scrub more often or less often depending on the rider, terrain, and more.

But make no mistake, if you hit a jump side by side with a faster rider and neither of you scrub, they are still going to be staying lower, even in straight lines. Soaking up the suspension to stay low is still an extremely effective tool for your arsenal.

To be fair, though, I see a lot of Instagram videos of “scrubs” where the bike doesn’t start to get laid over until just after the wheels have left the ground, so the scrub was completely useless. Just looks cool to have the handlebars a few inches from the crest of the jump face. Usually these videos are just someone pre-jumping an acceleration bump on the face and they could’ve kept the bike upright and gone exactly the same speed while saving energy.

My first race was on a 125 that I had for about a week. It was beginner class and the rules stated that you roll every jump. I damn near got the holeshot then proceeded to get smoked by everyone who was doubling every jump, one kid even tripled. Needless to say I got lapped in beginner class because I did that whole single single all the way around the track.
