Two months in the past we have been the primary to identify this new Campagnolo Tremendous Document HPPM energy meter crankset within the wild – in essentially the most stunning of all locations – on the UCI Cyclo-Cross World Championships in Tábor, Czechia. And now the long-rumored, long-awaited Campy energy meter is lastly right here. These accustomed to the SRM x Campagnolo energy meter choice will see lots of similarities. However this new Campy HPPM crank has packed in new Excessive Precision Energy Measurement tech with extra pressure gauges than we’re used to seeing, to ship industry-leading accuracy at a lighter weight…
Campagnolo Tremendous Document HPPM energy meter crankset
Excessive Precision Energy Measurement is how Campagnolo describes their new spider-based energy meter. In actual fact, although its arms clearly labeled it as a Campy Tremendous Document crankset, the Italian part maker solely ever instantly refers to it because the Campagnolo HPPM energy meter. That leans into the concept that they’re specializing in the tech inside, greater than updating their already costly top-tier wi-fi highway bike groupset.
What new tech is inside?
Now, what’s inside are 16 pressure gauges organized in 4 separate Wheatstone bridges and a 1 gyroscope. That’s so that you get exact torque measurement accuracy all through the complete 360° pedaling. You get computerized lodging of temperature adjustments. And also you get high-frequency knowledge sampling that measures angular velocity (cadence) each 5 milliseconds for clean energy curves (200x per second).
These Wheatstone bridges are a bit distinctive in that essentially the most correct in-arm energy meters (E.g. Infocrank) have a tendency to make use of 1 Wheatstone bridge per arm with 4 pressure gauges to make sure accuracy & temperature compensation. Essentially the most correct spider energy meters (E.g. SRM) are inclined to have 1 or 2 Wheatstone bridges per arm with 4 pressure gauges every to make sure accuracy. Campy has 4 Wheatstone bridges positioned across the spider (presumably at every arm connecting to the chainrings) with 16 pressure gauges in complete.
The ensuing energy measurement accuracy is alleged to be +/-1% (max 4000W energy measurement), making the Campagnolo HPPM on par with the highest
Campy Tremendous Document HPPM energy meter crankset particulars
This whole Campagnolo Tremendous Document HPPM energy meter crankset is alleged to weigh simply 656g (172.5mm with 45/29T rings, bearings & crank bolt). That’s simply 38g greater than a regular Tremendous Document crankset with no energy meter. Or down a full 124g from 780g for the similar-looking SRM Campagnolo energy meter with compact chainrings.
The Tremendous Document HPPM crank retains a slim Q-factor of 148mm, up 2.5mm from normal SR cranks. (And nonetheless 17mm narrower on the BB axle with a 130.8mm U-factor to attenuate crankarm rub). And it makes use of the identical new 4-bolt 121/88mm bolt circle diameter launched with Campagnolo Tremendous Document Wi-fi for the ultra-compact gearing that matches the most recent 12-speed cassettes with 10T small cogs.
My Campy & Wi-fi compatibility
The most recent model of the My Campy 3.0 app f0r iOS or Android helps you to rapidly calibrate the brand new energy meter and examine battery cost standing. The Campagnolo HPPM energy meter has a claimed runtime of 5 weeks or 2500km on a single cost. It’s recharged in 3 hours, 45 minutes by way of the identical 2-peong magnetic USB cable as Tremendous Document Wi-fi. And the li-po rechargeable battery inside could be changed by Campagnolo.
The Campagnolo HPPM energy meter is rated IP67 waterproof. It communicates by way of ANT+ & Bluetooth at 2.4GHz. Campagnolo licensed it to be used in North America, EU/UK, Australia, New Zealand & Japan.
What’s completely different than what we noticed at CX Worlds?
Apparently, the clearly cyclocross race-ready prototypes that we noticed in February on Ryan Kamp gold Colnago G3X CX bikes weren’t precisely what we see right here. Kamp’s prototypes all appeared to incorporate the brand new HPPM energy meter spider. However they nonetheless have been utilizing the earlier era crankarms with the small bulge, nonetheless seen on present Document & Refrain carbon cranks. Kamp’s cranks additionally look to have the smaller diameter BB spindle of lower-tier cranks.
What is particularly fascinating although, a brand new bottom picture that Campagnolo has supplied of the brand new HPPM energy meter reveals that the Tremendous Document arms are fitted to the spider with a 4-toothed lockring. And seem to only be clocked with a hole pin that strains up with that small exterior opening within the carbon crankarm. That implies extra crank arm choices (and barely decrease pricing) will probably be a simple replace to roll out sooner or later.
Campagnolo HPPM energy meter – Pricing, choices & availability
The brand new Campagnolo HPPM energy meter crankset sells for $2449 / 2240€ fitted to a set of Tremendous Document hole UD carbon arms with a Extremely-Torque titanium axle and USB ceramic bearings. For that value, you choose from 170, 172.5, or 175mm arms and the most recent SRW 45/29, 48/32, or 50/34T chainring combos. And also you get the proprietary magnetic USB charging cable, that might additionally cost your Tremendous Document Wi-fi derailleurs.
An entire Tremendous Document Wi-fi groupset was already going to price you 5200€. Deleting the usual cranks would save ~$950/1000€, presumably tallying the price of an entire Campagnolo Tremendous Document Wi-fi construct with an influence meter as much as round $6900/6440€. We’ve requested Campagnolo to substantiate groupset pricing, and that the brand new HPPM energy meter ought to be accessible to shoppers beginning immediately. And we’ll replace as quickly as we obtain affirmation.
Lastly, do not forget that Tremendous Document doesn’t appear to be very prominently listed within the Campagnolo HPPM naming. Learn into that, what you need, however we couldn’t be totally stunned to see an HPPM energy meter spider pop up at different factors within the vary. Possibly on a barely heavier, barely cheaper set of Document or Refrain arms, or dare I say an off-road-ready Ekar HPPM energy meter crank.
