I have a Fluid2 CycleOps trainer. Is there any way to mod it or incorporate a power meter to measure watts? Thanks
Get an SRM, PowerTap or Quarq for your bike? Unless you make one yourself, there isn't a way to bolt on a power meter to that particular model.FortOrdDirt said:I have a Fluid2 CycleOps trainer. Is there any way to mod it or incorporate a power meter to measure watts? Thanks
Generally true; I'd also suggest pumping your tire to the same PSI and making sure you tighten it to the same pressure each time as these can definitely effect wattage.upstateSC-rider said:Do yourself a favor and get a computer that has a rear wheel sensor and cadence, I like the Cateye Astrale 8.
Specific power doesn't matter one bit, as long as you train consistently, ie. constant speed & cadence in a known gear, you'll be fine.
Most wireless computers don't have a strong enough signal to read from a sensor mounted on the rear wheel. You can try yours to see what you get, but don't be surprised if it doesn't pick up the signal reliably.FortOrdDirt said:alright thanks. Well I was taking some spin classes and they gauge effort in watts n such,.. Why a rear wheel sensor? I have a cateye micro wireless at the moment
It would be a different forumla for each trainer. You will have to contact the manufacturer to see if they have a formula or chart plotting speed vs. power under a given set of conditions such as tire pressure, etc. Another method is to develop your own chart by borrowing a friend's power meter for a session. Not very precise in between chart values, and won't pick up any short bursts, but if you have nothing else and want to minimize cash outlay...FortOrdDirt said:Do you happen to have the formula or what its called MightySchmoePong? Thanks that sounds good
This is key.Circlip said:I'd agree with the other poster though who said that it does have some value also to go by speed only if you can repeat conditions, so long as you don't want or need to compare with values obtained by other people, or on other equipment.

One of the main things I used a power meter for last season was tracking my chronic training load (CTL) as the season progressed. I could use it to back off or ramp up my workouts, in order to prepare myself for goal races, races with particular physiological challenges (long climbs, time trials, short/punchy climbs, etc) and the like.
Without a power meter, if I were to put any stock into how long it takes me to climb to the top of the local loop, I'd assume that my fitness was going backwards in a hurry. I'd have no clue what was happening to me, or why. What were once excellent, tacky trails are now dry, dusty, and otherwise blown out. Great for practicing technical climbing, as I have to shift my weight around quite a bit in order to get any traction, but pretty poor if I were timing myself on the uphill.
LOL! Why would a company that has a major portion of their business invested in selling power meters, develop and provide you with a simple formula or chart that would allow you to derive and observe some basic power data without buying one of their power meters?FortOrdDirt said:I emailed the Saris/cycleops company to see if there was a formula for their trainers, and they said there was no such thing. Is there something on the internet?
Actually KK sells a bike computer (http://www.kurtkinetic.com/power-computers-c-22-l-en.html) and these numbers might be what you program to set it up for your particular trainer.FortOrdDirt said:Thank you! :thumbsup: Thats exactly what I am looking for. Just wondering, what is the A and what is the B?
