This model is assembled within Shimano's stunning Ultegra R8000 crankset and measures the individual power output of each leg.

The app also allows you to enjoy over-the-air upgrade capabilities such as adding new features and updates.

3T Discus C45 Ltd Stealth WheelsetIdeal for riders who want to upgrade their existing road or gravel bike, this wheelset delivers fantastic aerodynamics, strength and comfort on every ride. It features a unidirectional carbon ultralight construction, which allows you to benefit from its incredible strength to weight ratio. Aerodynamically optimised but shallow enough to keep you fully stable in strong crosswinds, these rims are light on climbs, ultra-durable and ensure lasting comfort. If you're likely to encounter poor road surfaces, gravel or even some light single track on weekend adventures, these are the rims for you.With the aerodynamic performance of the very best 60mm deep rims but in a 45mm format, the C45 rims mean that you can roll faster for longer. The wider rim section means that a standard 25mm road tyre sits at 28mm wide - not only ideal for a 3T Strada frameset but saving on weight of wider stock tyres.Remarkably, the aerodynamic properties of the C45 are retained all the way up to 40mm gravel tyres, giving you the flexibility to explore untrammelled tracks and poor surfaces at speed. If you value comfort as well as maintaining peak performance and rolling speed in harsh conditions this is a solid choice.Futureproof and forward-thinking, each set of C45 wheels comes with both SRAM XDR and Shimano driveshells so that you can swap the wheels onto future iterations of your bike when the time comes.The asymmetric carbon construction of the 3T Discus C45 Ltd Stealth Wheelset's rims allows for spokes to be offset - compensating for the space required for cassettes and brake rotors on the hubs. This enables wheels to be built with equal spoke angles on the drive and non-drive sides and crucially for you means greater stiffness and lasting durability. - Ideal for premium all-road/gravel/adventure bikes- Ultra-lightweight unidirectional carbon fibre construction- 700c with 45mm deep section but aerodynamic properties of 60mm- Innovative offset double angle drilling for maximal stiffness- Tubeless-ready clincher formatFeatures: Material: Unidirectional Carbon - ultralight layupUse: Road, Gravel and AdventureRim Size: (28"/700c) 32mm wide, 45mm deepETRTO: 622x25cTubeless Ready: YesType: ClincherSpokes: Sapim CX-Ray Straight-pull, Stainless Steel, black finish, double-butted aeroSpoke Count: Front: 24; Rear: 24Hubs: 3T GW Bombproof Hubs, Centerlock type, oversized light Alloy hub bodies, spindles & freehub body, adjustable bearings, black satin anodisedFreehub Option: Shimano/SRAMWheel Size: 700cNipples: Sapim chrome-plated brassFront Hub Spec: Thru-axle 100x12mmRear Hub Spec: Thru-axle 142x12mmRear Hub Compatibility: 10/11s Shimano freewheel and SRAM XDR Driver body includedSingle or Pair: PairPart Number: 3T7009DQDF81W Weight: 1640gBuy 3T Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
