The Shimano Dura-Ace R9270 Di2 power meter groupset is Shimano's flagship 12-speed electronic disc groupset with the FC-R9200-P dual-sided power meter built into the chainset. You get WorldTour-level Di2 shifting, Servo Wave hydraulic disc brakes and accurate left/right power data, all from one complete kit, shipped from our UK stock with pre-bled brakes.

At a glance

  • Dual-sided power meter – the FC-R9200-P measures each leg separately, so you see true left/right balance rather than one leg doubled.
  • Works with your head unit – Bluetooth LE and ANT+ connect to Garmin, Wahoo and other bike computers and training apps.
  • 12-speed Di2 shifting – wireless ST-R9270 levers; the front and rear mechs are wired to one internal battery.
  • Faster shifting – Shimano quotes rear shifts 58% faster and front shifts 45% faster than the previous 11-speed Dura-Ace Di2.
  • Hydraulic disc brakes – BR-R9270 flat-mount calipers with Servo Wave levers for strong, quiet, well-modulated braking.
  • Configured to you – choose crank length (165–175 mm), chainrings (50-34, 52-36 or 54-40) and rotors (160/140, 160/160 or none).

Choosing your setup

Crank length

Most UK riders between about 1.70 m and 1.85 m ride 170 or 172.5 mm. Shorter riders, or anyone working on hip angle or an aero position, often choose 165 mm. If in doubt, match your current bike or ask your bike fitter.

Chainrings

  • 50-34T – the best all-round choice for hilly sportives and long climbs.
  • 52-36T – the most popular race ratio; with the 11-34 cassette it still gives a 1:1 climbing gear.
  • 54-40T – for strong riders, time trials and fast flat racing.

Rotors

Choose 160/160 mm for the most braking power, 160/140 mm for a lighter race setup, or no rotors if you are keeping your existing Centre Lock rotors.

Compatibility

  • Frame: needs internal Di2 routing, flat-mount disc brakes and space for the internal battery (usually in the seatpost).
  • Wheels: any disc wheel with a Shimano HG road freehub (11- or 12-speed).
  • Bottom bracket: Hollowtech II 24 mm spindle (BSA, press-fit and T47 options available).
  • Don't need power? See the standard Dura-Ace R9270 Di2 groupset, or the Ultegra R8170 Di2 power meter groupset.

Frequently asked questions

Is the power meter dual-sided?

Yes. The FC-R9200-P measures left and right legs separately and reports left/right balance.

How is the power meter charged and updated?

With the charging cable supplied with the chainset. Pairing and firmware updates are done through Shimano's E-TUBE app.

Is the groupset wireless?

It is semi-wireless. The levers are wireless, and the front and rear derailleurs are wired to one internal battery.

Do I need to bleed the brakes?

No. The hoses come pre-bled and attached. If you shorten the hoses for your frame, a top-up bleed is needed.

This groupset ships from our UK stock and is normally dispatched within 5 working days. Standard UK delivery is free on orders over £200.
