Subject: Water bottle/front tire collision
I did the Timberman a couple weeks ago, my first HIM.

Near the end of the bike, a water bottle bounced from the seat of a fellow in front of me, and started rolling toward me. It was heading straight for my front tire. I was going about 25 mph at the time.

Luckily, the bottle swerved and missed my tire by an inch or two.

For whatever reason, I keep picturing that bottle rolling toward me, and I wonder what would have happened if I had hit it. Does anyone know?

Would I have crashed or would the bottle have bounced off the tire?

Thanks in advance for any responses.

Rear wheel you probably would roll over it, front wheel a very good chance it takes you out.

A skill you should have (or be working on) is bunny hopping. If you can't do it, practice. If you can, don't worry about rolling objects.

It's possible either could have happened, but it's more likely for it to wedge under your tire and cause a crash.

At an aid station at IMAZ 08 the guy directly in front of me went right over the handlebars when he hit a dropped bottle.  We were going around 15 mph and I managed to miss him by some miracle.  I saw a crash on the STP from a fallen bottle; the person didn't see it and rode straight into it.  This time they didn't flip but just went down in a heap. 

Bottles are dangerous.  It's why when you see a dropped bottle everyone should shouting "bottle! bottle!" so as to warn everyone.

I was in a group charity ride and somebody's Profle Design aero bottle slipped out. The guy behind him swerved it with his back tire. Down he went.

At a 70.3, I saw a lady hit one going into aid station.  She was hurt pretty badly.

At Vineman a few years ago there were a few areas where the road was a little rough and there were bottles all over the place.  I was starting to get a little peeved that people couldn't do a better job of securing their stuff.  I had one roll in front of me on a 40+ mph descent.  HR spike.

I'm constantly amazed how this skill seems to elude so many cyclists, especially given how important it can be.

Yes, a dropped and rolling water bottle is a very scary proposition to manage. I recall a race few years ago where I actually hit the water bottle and I was traveling upwards of 40mph when I hit it. Miraculously, I managed to stay on the bike. To this day I still ponder how injured I would have gotten had I fallen. People really need to hold their bottles securely and warn others if they have dropped them. Particularly on any downhill sections of a course.

I was thinking the same thing. I ran over my water bottle with my back wheel on Saturday. No problem keeping the bike up, but I suspect it would have been different if I ran over it with my front wheel.

Not that I am advocating this, but one time my back wheel went over the shoulder of someone who crashed in front of me and I kept the bike upright. The back wheel can handle a lot more than the front without affecting stability.

If it's empty, you stand a good chance of smooshing it and/or popping the lid off.  With the "old style" of water bottle with the snap-on kind of lid, this will happen.   If it's full of water and/or has a screw-on type lid... it's probably going to take you out.

I saw a full, unopened pint coke bottle stop a Jeep with 31" tires.  Jeep was in a parking lot and rolling slower than 10mph... but still... it wedged in there and stopped the jeep cold.

Oh it is real.

If you want to waste several hours of your life google/youtube Danny Macaskill. Some of the most amazing bike skills you will ever see. Of course it comes at a price---the guy has been constantly injured for several years. You usually only see the successful landings on youtube.

Sorry. Thread hijack over.

Quick question wrt bunny hopping.  I can do this no problem on my road bike (often used here in NE to avoid 8" deep potholes that appear out of nowhere from the previous winter).

But, I haven't ever tried this in aero.  Do you just grab hold by the shifters and it's the same move, or do you have to get your hands to the bullhorns in time?

Thought I'd ask before I try (and create one of the videos you don't see on youtube).

I can probably clear 3-4 inches while in aero, going fairly fast, but it is nerve wracking. If I had time, which in this situation (the rolling water bottle) you don't, I would do it from the bullhorns.

If you want practice, try hopping over the expansion joints in the road or a small pothole on your next ride. One of my standard loops has a bridge on it that is probably close to an inch higher than the pavement leading up to it. I can hop on to the bridge, in aero, without ever slowing down. Hopping a rolling water bottle would be scary but doable in aero.

x2.

Another option, in a pinch, would be to just lift the front tire.  As stated earlier, hitting it with the rear would be less problematic.  You can definitely lift the front wheel while in aero.

the only thing about "only" hopping your front is that you're going to be a LOT less stable in aero when your back wheel pops up off the bottle.

2:20 in Fabian shows how to do it right.

Yes,
If anyone is aghast about clearing the height of a bottle, its not all about height. Should be said that simply the attempt can improve one's odds.
Just unweighting the bike timely can keep one shiny side up for a host of road hazzards; potholes, glass, treefall, improperly oriented storm drains, speed bumps, railroad tracks, roadkill, etc

Just gave it a go on my lunch ride.  Easier than I thought, but I did have to shift weight a little to get a good jump - otherwise I found that it was more my front wheel that came up if I approached it with the same moves as on a road bike but straight from aero.  A little pre-jump unweighting off the seat helped to pick the rear wheel up along with it.

Still only got a couple inches off the ground, but that'll come with practice, I suppose.

Thanks for the advice.

And now back to your regularly scheduled post...

I actually did 'jump' an entire person once, in a training ride, sort of, and it speaks to Chris' (good) point, above -- there are better and worse ways to let a wheel hit an obstacle, and sometimes hitting an obstacle is unavoidable for us mere mortals.  (Maybe Fabian can literally jump a person, but I can't.)  If you lift the front wheel (lean back and lift) then immediately once it is clear of the obstacle, lean forward and lift or at least unweight the rear wheel, you have a decent chance.

Yes, this really happened to me -- the guy to my left and just in front went down hard and fast right in front of me, no time to brake.  (I was on a road bike, in the drops, not in aero on a tri bike, but the same principe applies.)  I lifted the front wheel and then the rear, as described.  It wasn't a bunny hop so much as taking my weight off of the wheel that was hitting him at the moment.  He ended up with bruised ribs.  It could have been much worse.

You can (and IMHO, should) practice this move (as well as bunny hops) on curbs or the like.  If your wheels are properly unweighted when they strike, they will easily just 'bounce' over and not cause you or your bike great harm.  If you are worried, practice first on a crappy bike with crappy wheels.

Rocket Science Sports has applied its hyper-technical approach to designing a water bottle. The result is a water bottle with dimples similar to those on a golf ball.
