ENVE G SES 4.5 Front Gravel Bike Wheel

The ENVE G SES 4.5 Front Gravel Bike Wheel is built for gravel riders who want aerodynamic efficiency without giving up climbing feel or handling precision. With a 49mm front rim depth and 30mm internal width, the rim is shaped specifically around the wider, higher-volume tires that modern gravel racing now demands — tire sizes that create real aerodynamic opportunity once the rim profile is matched to them.

At the core of the wheel is ENVE's Premium INNERDRIVE hub, a straight-pull design with an oversized 42mm ratchet drive positioned inboard, over the bearings. That placement reduces stress on the axle and bearings for more reliable engagement and longer bearing life. Paired with a Wide Hookless Bead carried over from ENVE's M Series mountain wheel line, this wheel adds impact resistance and pinch-flat protection not typically found on an aero-focused gravel wheel.

Who It's For

•        Gravel racers and fast group-ride riders who want aerodynamic gains at higher speeds without stepping up to a heavier, deeper aero wheel

•        Riders running wider, higher-volume gravel tires who want a rim width matched to that tire for clean airflow

•        Riders who value low weight and nimble handling over maximum aero depth — for a deeper aero profile, ENVE's G SES 6.7 is the category alternative

•        Not a fit for riders needing rim-brake or non-Centerlock disc compatibility, since this wheel is disc-only with a Centerlock interface

What to Look For

•        Confirm axle and rotor compatibility: this front wheel uses 12x100mm thru-axle spacing and a Centerlock brake interface — lockrings are not included and must be purchased separately

•        Check tire compatibility: the hookless rim design requires tires rated for hookless rims and a correct tubeless setup

•        Match rim depth to your riding priorities: the 49mm front depth favors gravel racing and stability over an ultra-light, all-around touring build

Key Features

Rim and aerodynamics: the 30mm internal width and 49mm front depth are sized around today's wider gravel tires. As gravel tire widths have grown for comfort and flat protection, the rim widened to keep airflow clean across the sidewall — the source of real-world aero gains at the tire sizes gravel riders actually run.

Hub: the Premium INNERDRIVE hub uses a 100% ENVE-designed 42mm ratchet drive with automatic preload adjustment, so there's no manual bearing preload to set or maintain. The front hub weighs 109 grams on its own, part of a 326-gram front-and-rear hubset, and is built for low maintenance and easy field servicing.

Spoke build: the wheel is laced with Sapim CX-Ray spokes, Alpina Nylock brass internal nipples, and built to 120kgf spoke tension — a spec aimed at durability and tension retention rather than the lowest possible static weight.

Brake compatibility: braking runs through a Centerlock disc interface; lockrings are sold separately, so factor that into your build cost if you don't already have one.

Rider Intent Summary

•        Biggest strength: rim width and depth tuned to modern high-volume gravel tires, delivering aero benefit at the tire sizes riders actually use

•        Tradeoff: the 49mm front depth favors speed and stability over the lowest possible wheel weight — riders chasing minimum weight should compare against ENVE's shallower gravel options

•        What makes it different: the Wide Hookless Bead borrows impact protection from ENVE's mountain wheel line, a durability feature uncommon on an aero-focused gravel wheel

Victory's Take

We spec the G SES 4.5 for riders who race or ride gravel fast and want aero speed without a weight penalty. At Victory Bicycle Studio, we'll confirm your hub spacing, rotor, and tire setup before you buy so the wheel bolts on and rides right the first time.
