Campagnolo's new PressFit cranks and internal EPS battery

Detailed look at the installation of the new cranksets and internal battery

Campagnolo cranks have been compatible with PressFit bottom brackets with the use of adapters, but now the Italian component maker has two dedicated cranks for PressFit systems, the Over-Torque Comp Ultra and the Over-Torque Comp One. Using a one-piece BB30 spindle, the Over-Torque cranks are compatible with existing BB30 bearings. Campagnolo will also offer its own bearings in both steel and ceramic versions.

The 11-speed cranks are standalone components, separate from the Italian company's gruppos. The 563g Comp Ultra has hollow arms ($870/€651/£TBD), while the 605g Comp One ($725/€491/£TBD) has solid carbon arms like the Chorus and Athena cranks. Both come in 170, 172.5 and 175mm lengths with Campagnolo's proprieary 110 and 135mm bolt circle diameters.

"It’s probably our simplest bottom bracket to install into a frameset," said Campagnolo's Dan Large. "It does require two new proprietary Campagnolo tools — an installation tool and the removal tool — plus a lockring spanner."

Also, Campagnolo gave BikeRadar a demonstration of installing the Version 2 power unit for its electric EPS groups. At 132g, the internal battery is 50g lighter than the current external EPS battery. Campagnolo claims that this cylindrical battery, which can be tucked in either the seat or the downtube, will last for about 1,700km for each charge. A full charge from empty takes about three hours. There is one $585/£TBD model for Super Record and Record EPS groups, and a $480/£TBD design for Athena groups.

To fit into the seat tube, the Version 2 battery requires a seat tube inner diameter of at least 26.6mm. While bikes with standard seatposts should accommodate this just fine, bikes like the new Trek Madone and bikes with narrow aero seatmasts will not. The battery can be mounted externally — and it has adjustments for pitch and yaw to tuck away at the required angle — but the primary idea with this design was to be tucked out of sight inside a frame.
