Campagnolo Super Record Wireless: The Italian Alternative

/ 01

Why Campagnolo matters now

For 30 years Campagnolo was the only alternative to Shimano at the top of road cycling. Then SRAM arrived, then electronic shifting arrived, and Campagnolo spent 2018-2022 looking like it had missed the wireless revolution. Super Record Wireless (launched August 2023) is the response — and it's a genuinely different philosophy, not a Shimano clone.

Where Shimano optimizes for shift speed and SRAM for ecosystem flexibility, Campagnolo optimizes for shifting refinement and gear-step smoothness. The cassette jumps are tighter than either competitor. The crankset is the lightest of any top-tier groupset. And the industrial design — visible carbon, titanium hardware, ceramic bearings — is unapologetically Italian premium.

Cassette: the cadence-first philosophy

Campagnolo's cassettes start at 10T (like SRAM, unlike Shimano's 11T) but stop at 29T for the road version — far smaller than SRAM's 36T or Shimano's 34T bail-out gears. The philosophy: tight, even steps for cadence preservation, not low-end range. Single-tooth jumps run all the way to the 7th cog; after that, jumps are capped at 3T. For racers on rolling terrain this is ideal; for climbers or bike-packers, the 11-32T option (separate product) is the only sub-1:1 option.

The catch: the cassette mounts on Campagnolo's N3W freehub body, which is 4.4 mm shorter than the classic Campagnolo body and incompatible with Shimano HG or SRAM XDR. You need either Campagnolo N3W wheels or an N3W-to-HG adapter sleeve. This is the single biggest ecosystem lock-in of the groupset.

Crankset: the lightest of the three

630 g for a 172.5 mm 48/32T crankset is lighter than Dura-Ace FC-R9200 (685 g, same config) and RED AXS (689 g). The trick: a one-piece carbon spider that integrates both crank arms and the spider into a single molded unit, mated to a titanium Ultra-Torque half-axle system. USB ceramic bearings (Campagnolo's own, CULT-grade) are standard.

Chainring combinations are 50/34, 48/32, 45/29. The 45/29 is unusually compact for a top-tier groupset — it pairs with the 10-29T cassette for genuine climbing gears without going to a sub-compact crank. Q-factor is 147.5 mm (3 mm wider than the previous gen, to clear wider modern tires). Crank lengths: 165, 170, 172.5, 175 mm.

Brakes: the DB410 pad update

Campagnolo's flat-mount hydraulic disc brakes use the same architecture as the previous mechanical-shift version — the wireless update is cosmetic plus the DB410 pad, which is 30% lighter and saves ~12 g per caliper. Brake fluid is Campagnolo's own mineral oil (NOT Shimano's — they're chemically different, don't mix).

Brake feel is the firmest of the three brands — less servo-assist than Shimano, less 1-finger geometry than SRAM's E1 update. Riders coming from Shimano often find Campy brakes require more deliberate input; riders coming from SRAM find them more linear. Rotors are Center Lock, 140/160 mm, Campagnolo's own (cross-compatible with Shimano/SRAM rotors on the same hub).

Batteries: the quirk that matters

Unlike SRAM (one battery design, swappable between derailleurs) or Shimano (one frame battery for the whole groupset), Campagnolo uses two purpose-built derailleur batteries that are NOT swappable front-to-rear. The front derailleur battery (34 g) and rear derailleur battery (39 g) have different physical shapes and connectors. Lose one and you're ordering a specific replacement.

Battery life: 750 km of riding per charge (claimed), 60-minute full charge. That's roughly 3× longer per charge than SRAM's AXS batteries (~60 hours / ~1,500 km but with two cells). Charging is via USB-C directly into each battery — no cradle needed.

The three-way comparison: Shimano vs SRAM vs Campagnolo

These are the only three tier-one wireless electronic road groupsets in existence as of 2026. Choosing between them is less about which is 'best' (they're all superb) and more about which philosophy matches how you ride.
