In lacking a stand, I put my bike on the trainer to make it easier to install my new computer.

Once I got it up and running I decided to hop on for a second to test it out and decided to go for a hard sprint.

After the tunnel vision cleared, I was surprised to see 53.5mph as my max speed.

Now if I could find some way to eliminate air resistance so I could do that on the road...

Anyway, what's your max sprint on the trainer (or rollers)?

What was your resistance set to ?

That's pretty much a useless number without knowing how much resistance the trainer was applying. Might as well be 88mph.



Damned air...you could always ride in a vacuum. For short period anyway.

The highest possible.

there must be like no resistance on your trainer. i have hit a max of about 38 mph.

Cycleops Fluid2 is good for about 725 watts. Hence, you're going to be past the trainer's capacity well below a maximal 5-10 second effort.

I just got a KK Road Machine yesterday...haven't yet tried to push it but the potential for 3000 watts is daunting!

¿Que?

You overcame the resistance, and all power above that would have had none. "speed" on a trainer is pretty much meaningless anyway.

Gotcha.

I am new to serious training and I hit 32 mph (234W) for ~1 min today on the trainer. Total duration of the ride is 50 min.
I have read some BF members can maintain 300W for an extensive long period. It must require a lot of training and committment.

You should borrow my old Cat Eye trainer. It constantly says that I dial it up to 2600 watts and hit speeds of 60+

unless you were going downhill or had the frontal area of a knife blade, there is no way you could do 32 mph on 234w "outside."

regarding the 300w for an extensive period of time, you have to take weight info consideration. Someone who is bigger, where their weight is not fat, generally has more muscle to generate more power, but then it takes more power to move. That's why we usually discuss power as W/kg. For climbing it is more of a direct relationship than riding on flat ground. On flat ground it's really the frontal area that matters, which scales somewhat with weight.

Then you also have to define what "extensive" means. Often we talk of FTP which is functional threshop power, or the power you can average for an hour, rested, in race conditions. Most people estimate their FTP rather than test it directly, and use the estimTe to set training zones. If one does not do hour long time trials, they Re unlikely to ever actually "see" their FTP for an hour.

Yeah, my LT power was tested to be 302 watts. But I weigh 192lbs. That's only 3.45 watts per kilo... which puts me off-the-back in a hilly road race.

Damn, more iTypos than usual in that post. I'm not gonna go back and fix them, the page loads are too slow. Consider this a blanket apology...

FWIW, I had a FTP around 300 at my peak last season. At around 65 kilos, that was 4.6 w/kg and I still get dropped in very hilly road races, but I do ok in moderately hilly ones. I think I'm a category ahead of Rydaddy though...

I did ok in two somewhat hilly RR's this year (Leesville Gap and Winters RR). I'm not sure I'd call them moderately hilly though. Top 10's in both. I was a 5... will be a 4 in a couple weeks. I am focusing more on racing for 2010 so I hope to raise the W/kg and I have a plan to do so.

I read somewhere that on the moon, with no air resistance, 1/6th the gravity, and given the extremely efficiency of a bicycle's drivetrain, it should be possible to ride at about 2200 mph, given roads, traction, etc etc etc.

I figure a pedal powered railed (i.e. no need for traction - think roller coasters) transportation network wouldn't be far fetched up there. Of course you have to make the rails. Okay, never mind.

They have roads on the moon???
