Slowest wheel change ever?

I’ll give them props. They were quick with the wheel change. How about kawi cutting a brake line last year for Tomac after looking at it for 5min.

Slow AF
ISDE guys do a tire change in like 3mins.
Everyone was in a panic. I get it, not ideal situation by any means. He’ll lock it up in Vegas, just a little suspense.
Exactly! a complete tire change with bibs.
Let me add it's the rider doing the tire and wheel swaps too!

Old Katoom has axle pullers for switching wheel sets. RMATVMC “works” part, lol.

Interesting how “back in the day”, blown wheels were so common in SX/MX. Now flats and DNF’s are so rare, especially indoors.

Riders used to have to ride so as to save rims, now it takes a pretty big incident.

Herlings had to pull in to change his front wheel in the Qualifying race at Valkenswaard. Not sure if they run the same disc guard but it'd be interesting to see how long it took those guys in comparison.

I think everyone on here that posted how slow the tire change was needs to put up or shut up. Upload a video of yourself removing and reinstalling your front tire.
So that includes rolling your bike in, setting it up on the stand. Removing the front wheel, setting it down, then putting it back on and bolting it up safely as quick as possible. ML512 can we get a Vital tire changing competition going?

Here is the key, you have to think like a mechanic and have all of your tools that you could possibly need to disassemble/fix the bike in your back pack (not just the tools you need for the front tire) and also spare goggles and other things that the rider may need.

That last paragraph, when combined with ML512's entry, leads to one conclusion: Husky wasn't prepared. No team can forecast every mechanical issue, but most sports involving wheels pay very close attention to, well, the wheels. The spacer oversight demonstrates how the smallest detail can derail a seemingly routine event.

A 2 minute front tire change is quick...for a single person. For a professional racing team it's laboriously slow. Jason may finish 5th or better next week, making the fiasco a moot point. However, if an accident or another mechanical loses the title by a handful of points, that time in the SLC pits will signal how SX is truly a team sport.

I wasn't really surprised by how long it took the crew to change the wheel, but it did make me think about the hardware and the process. You would think tech would have evolved to allow easier (or maybe even tool-less) wheel changes. But the axle, fork leg, and wheel setup is fundentally the same as a Honda trail from the 60s.

What could be done to speed this up? These are race bikes after all. And anything that speeds the process up would also help with convenience for flat repair.

Tool-less quick release axle
Captive spacers
Some way to spread the calipers quickly

Really not that hard, already solved for dh bikes right?

F1 tire changes are so fast because the car is built to support the process. Built in jacks, and a single bolt for each wheel.

Not that anyone cares for another opinion but I assumed that they were inspecting the front brake as well since spokes broke and might have wacked into the caliper.

That's what I was wondering too. Is that even in the rules? He pulled over and then they rushed him through. Odd.

I tried to take a screenshot of it and I can't see it in the little box they showed him on the broadcast. It does look like he's slapping at his lever though! I'll post the GIF here soon.

How much effort would a team/factory want to put into something that happens so rarely? I think this was the first tire change that was shown on TV this entire SX season. (Maybe some guys in the back of the pack had to do it, but TV didn't show it?)

seeing that made me wonder why teams don't utilize their mules to hold all the spares and tools.

OP, post a video of you changing a front wheel! Show these guys whats up.

They do at the outdoor races. Where in the world would the teams keep them staged at a supercross?

For those saying how fast they changed that wheel, in club racing we were changing front wheels on our roadrace bikes in 2 minutes and we have to remove 2 brake calipers in addition to 4 pinch bolts and the axle. My guess is the mechanics don't practice fast wheel changes on those bikes, but if I was a team manager that would be a requirement, at least one or two per week just to keep in practice because you never know when it's needed.

What I saw seemed to be lots of confusion on how to put the wheel on it seemed. If the spare wheel used different spacers or anything else, that would for sure be a problem with the mechanic or team for not being ready.

This is as good reason as any for two way radios. "Hey guys my front wheel is busted I'm coming in for a wheel change - get ready"

It's hard to tell in my GIF (same as the HD broadcast) but it does look like he's slapping at it when Anderson rides away.

I'm not criticizing just a couple thoughts.

They bring spare wheels for this reason. But the tools were a scramble. So if you are going to take the time to bring a extra set of wheels, why not have the tools ready. If your going to use hand tools or power tools, have them always with the wheel set or wheel cart. I can see digging in a bag for a rare special tool or item.

But I couldn't imagine the thoughts in their head while trying to focus on the job.

In SX, if a part goes down to the line the mechanics need to be able to change it without having to think. Second nature. There's no reason to lug all that shit around if you have to pause and think about how to assemble it. Pipes, levers, wheels, foot pegs. If it's on the stadium floor then installation should be practiced during the week at a live test track and not in the shop. They should know the fastest and most efficient way to assemble anything they bring.

I noticed that too but sometimes people work the slowest when trying to go the fastest. Sometimes the disk is a pita to get into the caliper. Did anyone else see Wilson pull off too? Anyone know what happened with him? Seemed to me like he was offering up his bike for Anderson to ride the way he pulled in pointed at his bike and then pulled right back out but I would think he's smart enough to know it doesn't work like that.

I know the pressure these guys were feeling, when working at a major airline, I would get called to the gate with a 130 passengers in their seats and the plane has a mechanical issue. You want to get it fixed so the people dont miss connections, but you want it good before you send them 6 miles up in the sky doing 500MPH. And I didnt have any cameras on me ... oh well maybe I did! Wink


So to keep the pads spread, is there a wedge available with a streamer so they dont forget to pull it? Or maybe a piece of composite, like a dense sacrificial Styrofoam wedge that can be inserted, then the rotor pushes it out during wheel install? been a while since I been involved in wrenching on bikes.

I have several Honda Trails in the garage, no calipers, and the speedo cable can be a pain to get it clocked into the drive! (sorry, couldnt resist)

The stupid is strong in this post. Clearly they were unprepared. Yes that was twice as long as it needed to take. But give credit to the mechanic who is stressing on trying to figure out what is wrong with his rider who is in the points lead of an ama supercross championship. Even if he did change the wheel in under a minute, there was no way Anderson was going to make it back to the front of the pack. That could easily be done in a minute if all the stars were aligned, but clearly that was not the case.

was in the crowd for this race so didn't get to listen to the always knowledgeable Ralph, but can anyone answer this?

with 2 minutes plus 1 lap left did Ralph ask Jeff if it were possible for Anderson to catch Musquin by chance? because i think he had about the same chance to catch Marv as Eli did.
