Description
Introduction
The Wild Dragon II 85-27 is a 27.5-inch carbon fat bike rim built on the same double-wall triangular platform as the original Wild Dragon — the world's first carbon fat bike rim, introduced in 2013. With an 85mm external width, it fills the gap between the 65mm Black Eagle and the 90mm Wild Dragon.
The original Wild Dragon concept emerged from professional rider Ryan Melnyck, a former Canadian national champion in mountain cross country racing and multi-time provincial champion, who also works as a mechanical designer.
The triangular cross-section of the Wild Dragon greatly increases wheel strength. In its first stiffness test, the rim reached an outstanding result of 426 kgf — more than 4 times stiffer than a standard carbon mountain wheel. The roof surface easily sheds snow, mud and sand, and the smooth rim bed makes tire installation and removal noticeably easier.
In 2015, we introduced the 27.5-inch Wild Dragon to meet demand from taller riders. The 85mm version is a mid-wide option that works well with 3.8" to 5.0" tires, giving riders a balance between flotation and agility.
Since 2013, Wild Dragon has become not only a classic NEXTIE product but also a benchmark for carbon fiber fat bike rims worldwide. More than 3,000 riders across six continents ride Wild Dragon wheels today.
The Wild Dragon II 85-27 rim weighs 610g. Recommended tire size is 3.8" to 5.0", with tire pressure between 6 and 19 psi.
Who is it for
The Wild Dragon II 85-27 is ideal for:
Riders who want a mid-wide rim between the 65mm Black Eagle and the 90mm Wild Dragon.
Riders running 3.8" to 5.0" tires on snow, sand, mud or technical trails.
Taller riders who want a 27.5" fat bike wheel with correct body proportion.
Builders pairing it with 150mm or 197mm rear hub spacing on modern fat bike frames.
Design features
An 85mm external width fits a wide range of fat bike tires for four-season riding.
The 40mm deep section adds rigidity for more aggressive riders and heavy loads.
A deep channel between the bead seats makes tire installation and removal easier.
A compact bead socket locks tires in tightly for reliable tubeless setup.
The aero-style triangular profile sheds dirt, mud and snow as conditions get rough.
