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. Weight	Road Feel
ENVE SES 4.5	50 / 56 mm	25 mm	1432 g	Balanced Speed
ENVE SES 6.7	60 / 67 mm	23 mm	1457 g	Sprinter Aero
ENVE SES 3.4	39 / 43 mm	21 mm	1390 g	Lightweight Climbing

The 4.5 version splits the difference perfectly, lighter than deep-aero wheels yet faster than pure climbing rims.
