|Cycleops advertises a trainer that can produce up to 725 watts at 37 kph... will it continue going up for sprints? When doing out of the saddle sprints I expect to easily hit 1200 if not higher.

|Nick, I apologize if I misread your post. But it seems to imply that trainers produce Watts.. They do not - they just read the Watts the rider puts out. To get some idea what's involved, it helps to look a power diagram. For an 80 kilogram rider-bicycle combination on flat ground with no wind, there's a classic cycling power diagram showing the number of Watts that rider needs to produce to travel at a certain speed. |
Some values are: 30 km/h = 180 Watt; 50 km/h = 500 Watt; 60 km/h = 770 Watt; 70 km/h = 1,120 Watt.
The rider needs to produce these numbers to overcome the sum of rolling resistance plus air resistance. As speed goes up, rolling resistance increases at a much lower rate than air resistance. A good trainer simulates those rates as much as possible.
As you undoubtedly know, the more Watts you put out, the less time you can hold that number of Watts. Turning this around, the less time you need to hold a certain level of Watts, the more you can put out. So, as you said, you might in fact be able to hold 1,200 Watts for 10 seconds or so - a powerful, all-out sprint.

|The Kurt Kinetic and 1UpUSA models claim to have upwards of 1500+ watts, I believe. Of course, they're the most expensive ones out there too.|
|Check out 1up!||Anaerobic_Nut|

|Bought one 2 months ago and it claims to handle up to 2500 watts. I have a strong sprint and have not been able to max this trainer out yet. I previously owned a Cycleops as well and continually overpowered it so I gave it to my wife and bought the 1up. Don't regret it; plus its very quiet and should last a long time (no oil leaks). Go check them out!|| |
