Every night when we get down on our knees and do our bedside prayers, our first request of the Almighty is a friendly, enduring collaboration between SRM and Campagnolo. We so dearly want a true-blue Campagnolo Ultra Torque Professional Powermeter… Maybe we need to re-consider that sponsorship opportunity with Amore e Vita to score some divine intervention, because we're under a pretty strong impression that this collaboration ain't happening. Not now. Not in the foreseeable future.
If you ride a Campagnolo-equipped bike, and if you can't live without the real-time telemetry and rich post-ride data provided by a SRM Professional Wireless system, one truth is absolute: Buying an SRM Dura Ace Wireless isn't an option. It's not a compatibility issue. A good mechanic can make a DA crankset work passably well with an otherwise Campy drivetrain. Rather, it's a moral issue. Perhaps no industrial design hallmark further separates Campy from Shimano than this: Shimano loves their forging machines. Despite the carbon bits they've incorporated into the Dura Ace 7900 group, they're a company fixated first and foremost with pounding metal into elegant forms with gazillion-yen school bus-sized forging machines. Campy is the opposite. Their love affair with carbon is so deep that for years you've seen its trickle down use in even their Chorus and Centaur groups. It'd be heresy to install the one Shimano component most emblematic of their mad metal-fabrication skills -- a Dura Ace Hollowtech crankset -- on a bike otherwise dripping with Italian carbon.
So what is a power-hungry Campy aficionado to do? This system is your best option. It's the SRM FSA Carbon Professional Wireless Powermeter. Like the FSA K-Force Lite crankset, this system is built with an integrated bottom bracket spindle to maximize drivetrain stiffness. This system uses the identical Professional Powermeter as what you get in the Dura Ace Wireless system. The accuracy is the same, the battery life is the same, and all functionality is identical. Like the Dura Ace version, it comes with a Powercontrol VI. The only difference, in fact, is the crankset your Powermeter is housed in.
The Powercontrol VI that comes with this system works on the ANT+ wireless platform. This means that it can communicate with any other ANT+ compatible powermeter. Keep in mind, though, that while it is an altimeter, it is not a GPS. Because of this, you don't track speed and distance via satellite (like you do with a Garmin GPS). Rather, this system comes with a small wireless speed pod manufactured by Suunto. You can mount it either on your fork or on your chainstays (depending on whether you'd like to read speed from your front or rear wheel). Along with the speed pod, this system will also come with a Suunto heart rate chest strap transmitter. While the wireless SRM transmits power data to the Powercontrol VI via ANT+, speed and heart rate are transmitted via ANT (not ANT+) -- something to keep in mind in case you try to use the pod or the transmitter with another ANT+ device.
Along with the speed pod and transmitter, you'll also receive a small BB-mounted bracket impregnated with a magnet. For those of you familiar with the wired generation of the SRM, you'll note that it looks an awful lot like the head of a sensor cable. The purpose of this magnet is to read cadence, and you must install it -- even if you don't care about cadence. Why? It's because Power = Torque x Cadence, so with no cadence reading you get no power reading.
When you first receive your system, you need go through a quick "pairing" process. This creates an exclusive connection between your Powercontrol VI and your Powermeter, your speed pod, and your heart rate strap. By doing this pairing process, it ensures that you won't pick up your riding partner's signals, and it's also the means by which your Powercontrol reads the slope of your Powermeter. (And if you own two Powermeters on two bikes, but want to use just one Powercontrol, you'll go through this pairing process when you move your Powercontrol from bike to bike -- this ensures that the slope will be correct and your power reading will be optimally accurate.)
The only values you'll need to calibrate manually are the zero offset (this is no different from the wired generation of SRM) and altitude. In terms of the latter, you'll note that there's a GoreTex membrane on the back of your Powercontrol -- this is where barometric pressure is read from for altitude data. But for the sake of absolute accuracy SRM advises that you use Google Earth to determine your exact altitude at the beginning point of your ride, and enter this in your Powercontrol.
Please note that there is NO cross-compatibility between the SRM wired Professional systems and the wireless Professional systems. The only piece, in fact, that works for both systems is the handlebar clamp. The download cable, the charger, etc, etc are all non-compatible.
When you purchase this system, you'll get the following: The FSA Carbon Wireless Powermeter in the cranklength of your choosing (170mm, 172.5mm, or 175mm -- and this will come with a 53t outer chainring and a 39t inner chainring); a Black Powercontrol VI; an oversized handlebar clamp; a Suunto speed pod; a Suunto heart rate chest transmitter; a BB-mounted cadence magnet; a new generation charger/download cable (like an iPod's, this is a dual-function cable); and an instruction manual. You will also get an FSA Mega Exo bottom bracket specific to the SRM. Please choose English or Italian based on the threading your frame model requires. NB: Other Mega Exo bottom brackets are not compatible with your SRM. You must use this bottom bracket you’re your system!
The FSA system is unique in that the outer chainring needs to be 130mm BCD. The inner chainring needs to be 110mm BCD. If you choose to go with a different ring than the 53t that comes standard here, please note that special chainring bolt machining is required! Basically, both the outside and the inside of the outer chainring bolt holes need to be countersunk (typically only the outside part is countersunk), so either contact us or SRM for the replacement chainring you need. A non-SRM dealer will not have these rings available, nor will they easily be able to procure them for you.
Nothing is more convincing as you consider purchasing an SRM Powermeter as an understanding of the virtues of training with power. We've done our best to provide this with our article "Power: The Ultimate Training Metric". Reading it will be a worthwhile investment of your time, and please feel free to contact us if we can elaborate on any of the topics brought up there.
