I don't quite understand the fascination with the PT 2.4. Yeah wireless makes a cleaner bike but a well installed wiring harness isn't that big a deal. That and the 2.4GHz wireless transmitter has to drain hub batteries faster than the current SL or Pro models. I picked up from one of RDOs posts that they've gone to a coded HR strap and new HR receiver electronics with the 2.4 model, that's a nice upgrade but I still can't figure out why everybody's so excited about the new model. The PT SL is very reliable, very light and the wiring harness is pretty darn clean especially if you forego the crank sensor for cadence. The sharkfin wiring harness installs in minutes with a very clean line.Thom_y said:..... Yet, the early experience of a few with their PT SL 2.4 on this forum is making me hesitant to take the plunge just yet. ....
I've picked up PT SL race wheels, training/backup wheels and even a track wheel complete with the Surly fixed gear adapter from riders who just had to have the wireless version. All in all I've saved a couple of thousand dollars and outfitted several bikes with the wired models because folks just needed the wireless version. I don't get it. Heck, I'm not complaining but for those folks sitting on the fence over getting a PM why wait for the bugs to get worked out of the SL 2.4 when you can save some cash get a great and field tested SL or Pro version today? Is a clean and simple wiring harness that big a deal?
On another note, I used the Ergomo Pro PM for about four months and loved it. I'd still be using it if I hadn't scored these incredible deals on PT SLs. I couldn't pass up the chance to outfit my track and road bikes with PMs and couldn't afford Ergomos for all my bikes. But I did get a chance to ride my Ergomo Pro and PT SL side by side for a week or so. They both tracked each other very nicely with the Ergomo reading 10 to 15 watts higher most of the time which makes sense as its an "upstream" PM. The Ergomo real time display and interval functions blow the PT out of the water with real time and AP displayed simultaneously. Real time NP, IF and TSS display and interval on and off switching instead of just the interval on markers you get with the PT. The biggest downside of the Ergomo is the difficulty validating the power readings but you can at least calibrate it if you have access to a known accurate PM whereas you can only check the accuracy of the PT, you can't correct errors if you find them. Anyway, I don't see why you'd be interested in a polar which relies on things like accurate chain weight and vibration modes for accuracy and discount an Ergomo that has signifigantly less black magic in its power measurements. Yeah I know the difficultly validating power readings is a downside, but how do you validate the accuracy of a Polar unit?
