Zero SLR
Origin
Wilier Triestina is one of the oldest names in cycling, founded in Bassano del Grappa, Italy, in 1906. The 'Zero' line has been its flagship weight-weenie platform for years — Zero.7 and Zero.6 were rim-brake superlight climbers celebrated for skimming the UCI 6.8 kg limit. When the peloton shifted to disc brakes, Wilier faced the challenge of keeping that featherweight character while adding heavier disc hardware and full cable integration. The Zero SLR, unveiled in 2019 for model year 2020, was the answer: Wilier claimed it as the first ultra-lightweight racing frame to combine disc brakes with fully integrated cabling, at a claimed ~780 g frame weight. It debuted under the Total Direct Energie WorldTour squad and later served Groupama-FDJ, cementing its status as Wilier's no-compromise climbing race bike.
Specifications
- Frame
- Monocoque carbon, proprietary 'HUS-MOD' high-modulus fibre with liquid-crystal polymer resin and multi-directional fibre mesh
- Weight
- kg
- Drivetrain
- Electronic groupsets only (Di2 / eTap AXS) — internal cockpit channels do not fit mechanical cables; Ultegra Di2 / Dura-Ace Di2 / SRAM Force & Red eTap AXS
- Brakes
- Disc only, flat-mount hydraulic (Shimano or SRAM); 12 mm thru-axles (Mavic Speed Release)
- Wheels
- Wilier SLR38KC carbon (developed with Miche) on current builds; earlier UL/T38 carbon (CeramicSpeed) on launch team spec
The verdict
- Exceptional stiffness-to-weight — snappy acceleration and effortless climbing (~24% stiffer/gram than the old Zero.6)
- Genuinely light: complete builds hover around the 6.8 kg UCI limit with disc brakes
- Impeccable disc-brake control and comfortable, composed handling on technical descents
- Very high price and premium-only spec (electronic groupsets, integrated cockpit) — no budget builds
- Not aero — pure climber, so it gives up watts at speed to aero rivals on the flats
- Integrated cockpit and disc-only, electronic-only design make fit changes and DIY servicing harder
