The Shimano WH-RS370 is a versatile 700C disc-brake front wheel built for road and gravel riders who want tubeless capability without compromising day-to-day reliability. Shared across Shimano's 105 R7000 and GRX groupset ecosystems, it pairs a welded aluminium rim with a secure 12mm thru-axle Centre Lock hub — giving you confident braking, reduced wheel flex, and the freedom to run tubeless or standard clincher tyres.

Highlights

• Tubeless-ready rim: 19mm internal width accepts tyres from 28mm to 45mm width for road, endurance, or light gravel use.
• Centre Lock disc hub: Paired with a 12mm E-THRU thru-axle (100mm O.L.D.) for maximum stiffness and precise disc brake engagement.
• Welded aluminium rim: Low-profile 19mm deep rim keeps weight in check while maintaining the structural strength needed for disc brake forces.
• Straight-pull spokes: 24 butted straight-pull spokes (2.0–1.8–2.0mm) reduce aerodynamic drag and simplify wheel truing.
• Contact-sealed bearings: Hub internals are sealed against moisture and road grit for consistent rolling performance across conditions.
• Broad tyre compatibility: Suits 28–45mm tyres (28-622 to 45-622), giving riders flexibility across road, endurance, and gravel terrain.

Rim & Hub Details

The WH-RS370 rim measures 19mm internal width and 23.4mm external width, with a 19mm depth — a profile that balances aerodynamic efficiency with all-round durability. The welded rim joint and tubeless-optimised channel wall accept standard tubeless tape and valves. Rim tape is required for tubeless setup and is not included.

Braking & Axle

The Centre Lock rotor interface (compatible with rotors up to 140mm) is Shimano's preferred mounting standard for road and gravel disc hubs, offering tool-free rotor swaps with a cassette lockring. The 12mm E-THRU thru-axle delivers significantly more lateral stiffness than a quick-release hub, translating to more consistent brake bite and improved handling under load.

Compatibility & Fit

Front axle standard: 12mm E-THRU thru-axle, 100mm O.L.D. Rotor mount: Centre Lock (rotor sold separately). Designed for 10- and 11-speed Shimano drivetrains; the front hub has no freehub body. Wheel size: 700C (622mm BSD). Recommended tyre range: 28–45mm width. Rim tape required for tubeless setup. Compatible with Shimano 105 R7000 and GRX groupsets.
