ENVE G SES Wheels Go Wider & Fully Aero for Gravel

ENVE's new G SES series is a ground-up gravel wheel range built for the way modern gravel bikes are actually ridden: on wide, high-volume tyres at race pace. Rather than shaping a tyre to suit a rim, ENVE optimised the rim profile around the tyre — a deliberate inversion of the traditional approach — and tuned the front and rear rims differently so each does its own aerodynamic job across a spread of wind angles.

There are three wheelsets. The flagship G SES 6.7 Pro pairs a 35mm internal width with mixed 60mm front / 67mm rear depths. The G SES 4.5 Pro and G SES 4.5 both run a 30mm internal width with 49mm front / 55mm rear depths; the split between them is build, not shape — different hubs, spokes and nipples. ENVE describes the 6.7 Pro as its "fastest gravel wheel ever" for fast, wide-open terrain, and the 4.5 as the more versatile all-rounder most people would ride every day.

The core idea is that a tyre is the leading aerodynamic surface on a gravel bike, so the rim should be shaped to flow cleanly into it — not fight it. That logic only works if you commit to genuinely wide rubber, which is why these rims are spec'd around 44–52mm tyres. ENVE pairs that with its Wide Hookless Bead, a reinforced edge designed to resist pinch flats and spread impact loads over a larger area.

The catch is that the philosophy cuts both ways. Fit a tyre that is too narrow and you lose the aero benefit and, ENVE warns, court reliability problems. As Bikerumor noted, tyre choice also drives the aero story as much as the rim does.

ENVE's headline claim is that the G SES is the world's most aero-efficient gravel wheel, with the 6.7 Pro saving roughly 8 watts at 32 km/h and up to 25 watts at 48 km/h against its AG25 baseline. Against the obvious benchmark — Zipp's 303 XPLR (32mm internal, 54mm deep) — BikeRadar reports the 6.7 Pro is 1.5 to 15 watts faster depending on yaw, and the 4.5 Pro 0.25 to 6 watts faster. Cyclist cites a 14.2% drag reduction for the 6.7 Pro at 48 km/h versus Zipp's 10.9%.

The honest caveat: those gains scale with speed. On a hilly course, or at the more pedestrian pace most of us actually ride gravel, the advantage shrinks fast — and the weight penalty starts to bite.

The reviews converge on a single theme: ENVE bought aerodynamics with mass and with strict tyre constraints. Cycling Weekly even points out that part of the aero edge comes from ENVE sticking with steel spokes where rivals are moving to carbon — calling it, only half-jokingly, "a cheat code." Nobody disputes the wind-tunnel story; they question how often the average rider is going fast enough on smooth enough ground to cash it in.

ENVE prices the Pro models at US$1,400 (~R23 100) (front) + US$1,700 (~R28 100) (rear) — about US$3,100 (~R51 200) a pair, or roughly £3,499 (~R76 100) / €3,899 (~R73 100) — with the standard G SES 4.5 landing near US$2,800 (~R46 200).
