A first look at the new internal battery for EPS and first 30mm press-fit crankset

At the recent Core Bike Show we had a first look at Campagnolo's updated EPS V2 groupset, which now offers a lighter internal battery option, and Over-Torque, the Italian company's first 30mm press-fit crankset.


In a very short space of time it seems like press fit bottom brackets have become the standard on high-end road bikes, but Campagnolo has taken its time in offering a suitable crankset. Until now, you’ve had to use adapters, but that has changed, as for 2014 it adds the new Over-Torque crankset.

The new cranks use a 30mm axle with a redesigned crank arm which the Italian company claims is 5% stiffer than its regular crankset and also 5% lighter as well. Small gains but not to be sniffed at in a sport increasingly obsessed with marginal gains.

The cranks won’t be label with the familiar group names, instead there will be Comp Ultra (Record level) which weighs a claimed 540g for the cranks, while Comp One (Chorus equivalent) weighs a claimed 590g. The key difference between the two is that Comp Ultra uses hollow carbon arms, and on Comp One the arms are solid carbon.Those weights are without bearings.

The cranks come in 53/39, 52/39, 52/36 and 50/34 options and 70mm, 172.5mm and 175mm crank arms. Campagnolo will still continue to offer its regular Ultra Torque cranksets, this is an option for anyone with a PF30, BB30, BB386 bottom bracket on their frame.

To fit the cranks you’re going to need Campagnolo’s proprietary installation and removal tool.  The bearings are self-aligning which it reckons will ensure the bearings last longer and run smoother. The bearings can be popped out of the cups for easy bearing replacements. There’s a slim preload collar on the non-driveside crank, sandwiched between the crank and bearing, that can take out any play.

Campagolo EPS V2 now available

Campagnolo now has an internal battery, and here it is. The battery is much slimmer and lighter, by about 50g, than the previous EPS battery. Battery capacity is reduced by about 5%, which Campagnolo claim is good for 1,800km of riding, though of course that depends on how much shifting you do. With front shifts contributing an increased drain on the battery, riding in a mountainous area is likely to reduce that distance more than riding somewhere like Belgium.

The battery isn’t going to be compatible with a lot of frames on the market. It’s simply too large to fit inside some frames, especially those with an aero seat tube like the Orbea Orca. Alternatively, in such situations, the battery can be mounted in the down tube, but that is only doable if you can physically get the battery to negotiate the head tube/seat tube junction. If you can’t fit it internally,  it can still be fitted externally, to the down tube or chainstays.

For internal fitting, it’s designed to slide down into the seat tube and fix into place using two sided bottle cage bolts. It’s orientation can be flipped depending on the size of the frame and seatpost drop, smaller frames will probably need the battery installed cables first, which is said to be a little more tricky a job. To charge the battery when it’s concealed in the frame, the frame needs a dedicated port to access the charging wire, so you don’t have to whip the battery out every time. It’s not quite as user-friendly as Shimano’s new Di2, which has a mini-USB port located in the junction box to charge the battery. To switch the system off, magnets encased in a rubber band wrap around the area of the seat tube where the battery is, and switch the battery off.

The new battery can be used with current EPS groupsets, but you need to install the new DTI interface unit, which has been updated. This is the brain of the EPS groupset, its job is to monitor the state of the battery and check for system faults. Charge time for the new battery is claimed to be 4 hours. Weight is a claimed 130g.

If all that wasn’t clear enough, here’s a video Campagnolo has produced showing how the new internal battery is installed. 

There’s also a new 11-27 cassette option, which will be available at Super Record, Record and Chorus levels. I didn’t photograph it. So here’s a stock photo.
