    Rider X That was fun! @Matt, I thought for sure that you were going to hold it to the end solo.February 23 2016, 11:43pm
    popstarron Boy did I over estimate what I could do with this course. Nice workout everyone. Was that Dan who kept surging past me on the hills? How did you get your watts up over 7 on the downhill? February 24 2016, 7:10am
    MattVon I have been off my bike for a week and half :(.... Felt a little stale... I think the "ANT+ speed/cadence" method isn't comparable to power meters...February 24 2016, 8:32am
    bikesurgeon nice work popstarron! It was definitely me (Dan) trying to stick with you on the hills. I knew you had a computrainer and I've had the pleasure to ride on one of those before so I know how it's much easier to generate high watts on the uphills. Since I was on a fluid trainer, I could generate the same watts on the downhills (if I hadn't toasted my legs trying to keep up with you on the uphills). I think I'm finally over this cold I had for the last month so that definitely helped.February 24 2016, 10:09am
    bikesurgeon I completely agree with you MattVon. The "ANT+ speed/cadence" method is quite a bit easier if you ask me. When you let off the pedal a little bit, it doesn't affect your speed/cadence that much but your power will drop fast. That's what I've seen from about 5 rides with "ANT+ speed/cadence" method and 6 rides with Garmin Vector pedalsFebruary 24 2016, 10:12am
    bikesurgeon Also wanted to thank everyone for joining me on my birthday :) although I know you guys are dedicated and would be out there riding anyway...it was especially nice for you to let me beat you popstarron. It was the best birthday presentFebruary 24 2016, 10:14am
    popstarron Damn, I'm humbled by how gracious you guys are. Happy bikeday. I mean birthday.February 24 2016, 11:14am
    Rider X Happy birthday Bike Surgeon! @Matt, yeah I've been told that the speed/cadence sensor setup gives you a 40 watt bump in power. Nevertheless, I still thought you were going to solo to the win.February 24 2016, 11:54am
    MattVon 40 watts is a lot, but I think i've seen people cranking by me in 10w/kg + ranges with this configuration in other races. I think this why the zwift community will meltdown when they have massed start races...too much variablilty. It works here because everyone here seems to be reasonable gentlepersons...February 24 2016, 2:31pm
    Rider X Matt, the only way I'd be able to blow by you is to take all resistance off my wheel. February 24 2016, 3:40pm
    Roy Thomas i think ant & speed only is worth 50 watts more ..i was a super star last year ..rode 13.000km since and bought a power meter ..now i work for every km :) everyone buys when there ready thow February 24 2016, 3:48pm
    Roy Thomas was sick and still am ..maybe next week guys ( in my Arnold voice ! ) ill be back ! :)February 24 2016, 3:50pm
    MattVon So is the wattage just estimated off wheel speed? Is that how it work?February 24 2016, 8:21pm
    Roy Thomas yepFebruary 24 2016, 9:21pm
    MattVon ooh, that's not fair....;)February 24 2016, 10:22pm
    Rider X Matt, Art could explain it to you clearly. I think it depends on the trainer profile, the brand, model, tread and diameter of tire used, the amount of air pressure and how tightly you crank down the tension on the rear wheel. Lots of variables. I use a Kurt Knetic Road Machine, Michelin Pro Race 3 tires pumped up to 115 psi before every ride, and I crank down the tension on the rear wheel so that I barely get any slippage even when it's not warmed up. Now that still gives me more watts for the same effort as you're putting out - how much more I'm not sure. Phil, Justin and Shane say it's between 40 and 50 extra watts. And I still can't come close to you even with the bonus extra power. Next week, I'll increase my weight in TDG and see if that doesn't even things out a bit. I weigh 82 kilos now. How much do you think I need to increase my weight to eliminate my advantage? I was thinking adding 8 kilos or 17.6 pounds.February 24 2016, 11:07pm
    MattVon X - yeah. that makes sense. I wonder if Art has empirically tested those supported units to create the profiles or he is relying on vendor information.. I think the whole idea of this is to have fun. I don't think absolute comparison is really important. It does make it more fun if it is consistent from ride to ride, however and that the variability is due to the rider, not the equipment/settings. I think my performance here mirrors my real world ability fairly well. I'm light and I've always been very strong on climbs and time trials. Also my trainer wattage is pretty close to my Quarq meters, so I think I'm very consistent in that regard. I think Art should display real-time heart rate. If you see someone cranking 10w/kg up a hill at 130bpm, then you might not be comparing apples to apples, as they say..February 25 2016, 9:01am
