When all-around speed matters most, the ENVE SES 4.5 INDR steps forward. Designed originally for the cobbles and crosswinds of Paris-Roubaix, it offers real aerodynamic gain while supporting high-volume tires. Lighter than ever and tuned for better aerodynamics, this flagship ENVE wheel turns any road into a fast line. The redesigned construction keeps strength, drops grams, and maintains that smooth, controlled ride ENVE riders expect. Key Features at a Glance Average weight: 1432 g (+/- 3%) Rim depth: 50 mm front / 56 mm rear Internal width: 25 mm Aero tire range: 27–28 mm labeled Minimum tire size: 27 mm Tubeless tire only design Hub system: ENVE INNERDRIVE Premium Straight-Pull Brake type: Disc (700c wheel size) Light Design With Real-World Speed Each layer of carbon in the ENVE SES 4.5 is placed for the perfect balance of stiffness and comfort. The rim shapes are specific for the front and rear, letting the front wheel cut through the wind and the rear offer stiffness and maintain drive. The lighter laminate lowers total mass while keeping ENVE's proven durability. Benefits Quicker acceleration and easier climbing Refined ride feel with reduced vibration Aero improvement without penalty in weight Aero Profile and Performance The ENVE SES 4.5 INDR wheelset gains its speed advantage through CFD studies and real-road testing with the UAE-Emirates XRG Team. The wide rim and tailored shape handle gusts with control while sustaining drag reduction. The sweet spot between 50 mm and 56 mm depths keeps this wheel steady in crosswinds and stable under power. Tech Points Designed around 27–28 mm high-volume tires Performs efficiently through variable yaw angles Delivers speed over cobbles, climbs, and rolling terrain Tubeless and Wide Hookless Bead Like every premium ENVE wheel, the ENVE SES 4.5 INDR uses a hookless bead and precise diameter to ensure true tubeless fit. The Wide Hookless Bead reduces the chance of pinch flats by spreading impact stress. Riders can run lower pressures for speed and comfort. Advantages Tubeless setup improves traction and grip Lower rolling resistance on rough roads Stronger sidewall protection against impacts INNERDRIVE Hub System (INDR Wheels) At the core sits the ENVE INNERDRIVE Premium hub. Straight-pull spokes and steel ratchets cut weight and increase reliability. Positioned over the bearings, the ratchets lower axle stress and maintain smooth rolling. Hub Highlights 60 g lighter than the previous generation Inboard ratchet for improved engagement Anti-twist spoke holes for perfect tension Quiet, consistent spoke contact Tire Setup and Pressure Range The ENVE SES 4.5 INDR favors wider modern tires for efficiency and comfort. High-volume rubber rolls faster on rough patches and adds stability at speed. Setup Guide Ideal labeled size: 27–28 mm tubeless-ready Minimum tire: 27 mm Typical pressure range: 70–90 psi (4.8–6.2 bar) depending on weight and surface Rim tape width: 27 mm Purpose-Built for Real Courses ENVE first created the 4.5 for Paris-Roubaix's extreme cobbles and side winds. The modern version brings that same control to open roads, race circuits, and rolling terrain. This ENVE wheel rewards confident handling where surfaces vary. Why It Stands Out Stability that invites aggressive cornering Speed consistency on uneven ground Lightweight feel that still absorbs road harshness Comparison With Other ENVE SES Models Model Rim Depth Internal Width Avg.

Specifications Wheel size: 700c Disc brake / Centerlock Rim depth: 50 mm front, 56 mm rear Internal width: 25 mm front / rear External width: 32 mm Hole count: 24 front / 24 rear Effective rim diameter: 558 / 547 mm Rim weights: 411 g front, 415 g rear, 826 g set Wheelset weight with hub, tape, valve: 1493 g Summary The ENVE SES 4.5 combines low weight, wide-tire stability, and aerodynamic efficiency in one dependable wheelset. Its INDR hub system, refined carbon construction, and tubeless-only design make it the best option for fast stages and mixed terrain. For riders demanding genuine speed under real-world conditions, the ENVE wheel SES 4.5 delivers every time.
