What happens when you hit 400watts

Notices
Road Cycling It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle. -- Ernest Hemingway

What happens when you hit 400watts

I broke my first spoke because I am just too strong. (not blaming the wheelset at all )

I have a dura ace WH7700 wheelset. For those of you who don't know what they look like...



I am a smaller rider, at 155lbs, although I am pretty fast, and ride hard. I have about 1500 miles on these wheels, with a bunch of crit and fast michigan (read rough) miles.

On my group ride today, I was pretty quick and managed to drop all the riders by the 11th mile (we have a regroup point at about 13). On the way back, I was a little tired so didn't apply as much, and we finished with 3 other people. On the last mile, I normally use it as a cool down ride. We hit a light, wait, and as it turns green, 2 guys take off. I keep cooling down when one of my buddies says "lets catch them" I say what the hell and try and accelerate as fast as possible, when I hear a POP. I back off thinking thats not good. The guy behind me announces I broke a spoke. I ride for the last 1/4 mile at a slower pace and as I go to pull into the shop where we meet at, it starts making a ton of noise since centrifugal force was no longer acting on it and it fell through the hub. I get off and walk it the last 100 feet. Turns out it was the non drive side, right at the rim where it snapped. Oh well, at least I have spare spokes for that wheel set.

Dude, I'd snap those spokes in a moment. Those wheels and the small spoke count is asking for trouble. I'm surprised Shimano aren't hit with a trillion lawsuits from owners of those wheels who have lost skin from their face.

I have to rock double walled Sunrims with DT alpine spokes (the ones for tandems) to prevent snapping...

I know what you mean. I snapped a newer 8 speed MTB chain climbing a hill on Sunday on the rig. I guess I put too much power into the hill.

Haha not to lessen your accomplishment but my girlfriend also broke a spoke on that very same wheelset. She now rides Ksyriums and is much happier.

I wrecked a crank arm one time doing the same thing. I think I was in too low of a gear...


Edit: Whoops, typo. I meant too high of a gear... I was really mashing up that hill.

I shift my mountain bike as often as I do my track bike. Middle chainring, middle of the rear cluster, never shift at all. Can't wait for my new rig, and the new Giants look soooo awesome!

I destroyed my frame one time doing the same thing. It's hard finding a bike that can handle my power.

I snapped a frame once too, right at the bottom bracket, no way was it a bad weld.

At 400W all the decals peel off your bike due to superheating of the air as it passes over your frame.

I've heard molecules in your legs start to break down.

At 402 watts your feet fuse to the pedals and you truly become one with the bike.

None of you are breaking anything from power -- trust me.

My wimpy sprint is ~1000W, and everything's still intact after many, many sprints (MTB, Road Bike, and TT bike).

600W is like the typical standing start from a stoplight.

It's how long you can maintain 400W. Most recreational riders would be hard pressed to do it for 60 seconds.

Nah... 3 min V02 intervals are (for me) in that neighborhood...

Again, wattage isn't breaking your stuff -- promise. It's either assembled wrong, worn out, or just bad.

Wusses!

One day I accelerated so fast my rear tire burst into flames.

Caught my shoes on fire and burnt them right off my feet down to my asbestos socks, which I wear for just such an occasion.

One day I accelerated so fast that each molecule of steel in my bike dropped four protons so I ended up with titanium bike.

I've been known to affect the rotational speed of the planet when I'm in the mood and travelling East-West. Gets corrected when I accelerate back the other way though, so no harm done.

I'm careful not to dial up the Jiggawatts too high though in a pole to pole direction. Don't want to bugger up the magnetic field - that could be nasty.
