The ENVE G27 650b rims are ready to be built into the ultimate disc-specific gravel wheelset, designed to offer serious gravel riders a low weight, high strength performance upgrade.

There's a place between road and MTB open to discovery – somewhere beyond the range of your trail bike or the capabilities of your road bike. Terrain littered with challenges and technical demands. Higher tyre volumes and lower pressures require MTB toughness and flat resistance, while big days and long miles need the lightweight and efficiency of a fast-rolling road wheel.

With the G27, ENVE has created a wheel with the ride quality to make long miles enjoyable and multi-day treks possible while ramping up the fun, speed and ride experience.

The G27 gets its name from its 27mm internal rim width and is optimised for 27.5/650b XC 2.0 to 2.25 tyres. Riders who frequent rough and loose terrain or who primarily ride dirt, and prioritise traction and stable control over flat-out speed will gravitate towards the G27, benefitting from the additional air volume, durability, and anti-flat performance.

With a weight of just 320g, the G27 accelerates quickly and ascends with ease. However, it's not designed to be treated delicately – ENVE's G Series wheels have been tested to MTB standards tailored to the demands of gravel riding.

The rim has been designed with a bell-shaped profile for more vertical compliance and energy absorption. The result is a more comfortable and confidence-inspiring ride feel with added impact toughness that ultimately makes for faster riding. The G27 is tough and relentless on road, path or trail whether you're riding hard or going for a week-long adventure.

While the G27 has been designed from the ground-up as a dedicated gravel wheelset, it shares the Wide Hookless Bead technology seen across ENVE's M Series MTB wheels. This wide 4.5mm rim bead shape reduces the likelihood of pinch-flatting your tubeless tyre or cracking the rim by working in parallel with the rim's shape and carbon laminate to dissipate impact energy.

The G27 is intended for tubeless applications and features a moulded bead-lock to ensure that your tyres will remain secure and sealed to the rim over even the roughest terrain.

If your path leads to classics like Kielder100, AdventureX or further afield to Dirty Kanza, the G27 is your wheel.

Industry leaders in carbon fibre, every ENVE rim is handmade from raw uni-directional carbon at ENVE's headquarters in Utah, USA. The bespoke construction process utilises rim-specific carbon laminates, moulded spoke holes, removable bladders, and a gorgeous paint-free finish to reduce weight while maintaining strength, stiffness and allowing the beautiful handmade quality to shine through.
