SRM PowerMeter DuraAce 7950 Compact

£2,499.00 £2,299.00

Manufacturer: SRM GmbH

Product Information


The full system comes complete with the SRM Powermeter, SRM Powercontrol 7 (different colour options), Suunto heart rate belt, ANT+ speed sensor (frame / fork mounted), Oversize handlebar mount, cadence switching magnet, software plus manual and download / charging cables.

The Powermeter only comes with fitting instructions and the cadence switching magnet so can be used with either our current PC7 as a 2nd powermeter or with an ANT device such as the Garmin series.

Note the system can also be suppled with a standard bar mount, tribar fitting or quick release skewer speed sensor at no additional charge.  Please contact us if you need any of these options.


Shimano's development of the Dura-Ace Di2 electronic shifting system makes gear changes faster and virtually eliminates missed shifts, but the force on the chainrings is much higher than before. Therefore Shimano developed new DuraAce 7950 compact chainrings which are significantly stiffer. If you ride Shimano DuraAce 7950 conventional or Di2 - you benefit from increased power transmission.

Professional riders and enthusiastic Amateurs all rely on the SRM PowerMeter DuraAce 7950 compatible - especially for the hard mountain stages in the Giro D'Italia.
