FORK INVERT ENDURO - 15MM AXLE - 180MM TRAVEL (BCG0180)

Invert Enduro unlocks dirt bike confidence on your mountain bike. It brings the traction and smoothness of moto-style inverted forks to more riders with less cost and hassle. It’s the kind of game-changing component that will have you unlocking the trails and features you’ve dreamed of checking off. 

160mm - 180mm travel options

Overbuilt, moto-inspired chassis built to handle the weight, power, and speed of modern e-MTB. 

Dual axle compatibility: 15mm or 20mm 

Thrives in steep, fast, rough, and high-speed terrain 

For long travel trail, enduro, bike park, and electric mountain bikes

Note: Invert Enduro comes with a 15mm axle. (20mm axle available separately).

Why Inverted
The magic of Inverted forks is described in two words – Smoothness and Traction.

By placing the larger, stiffer tubes up top and the bushings closer to the axle, inverted forks better resist the fore/aft flex that causes binding friction and chatter. The inverted design also offers significantly more front wheel traction by allowing the tire to swim - not skip - through rough, loose, and off-camber sections.

Together, this produces the magically smooth, calm, and planted front end that inverted forks are known for. Moto figured it out first, and now mountain bikes have unlocked it.

SquareLoc Axle System
Two Axle Options

With inverted forks, the majority of the feel and performance comes from the axle. Invert Enduro’s SquareLoc axle keys to the dropouts, then locks in place with 4 pinch bolts to secure the entire fork together. This keeps the legs from twisting around the axle and adds all the needed torsional stiffness to the fork. With SqaureLoc, you can tune the exact flex characteristic of the fork to suit your preferences.

15mm Axle 
17-4 Pre-Hardened Stainless Steel 
Included with Invert Enduro 
Suitable for most riders 
17% more torsional stiffness than other inverted single crown forks 
Compatible with your current front wheel – the plug & play solution 
Gives max traction by allowing front tire to stay planted instead of skipping/deflecting 

20mm Axle 
17-4 Pre-Hardened Stainless Steel 
Available Separately 
Offers maximum torsional stiffness, steering precision, and most direct front end feel 
42% more torsional stiffness than other inverted single crown forks 
Optimal performance for heavier riders or those on full power e-bikes

E-Bike Ready
While it suits analog bikes just fine, we made sure that the Invert Enduro chassis was built to handle the weight, power, and speed of modern e-MTBs. 45mm diameter upper tubes paired with 38mm lower tubes and our SquareLoc axle system make the Invert one of the most robust single crown enduro forks available. We wanted a fork that would allow us to fully utilize our e-bikes' abilities to do more laps on the most challenging downhills. We hope you brought your range extender...

SideSwipe Guards
Protection Where It’s Needed 
Dirt bikes and motorcycles use fork guards that face forwards to protect the stanchion tubes from debris being kicked up at high speed by the riders ahead. Mountain bikes simply don’t have this problem and therefore don’t need their fork guards placed in the same orientation. Invert Enduro’s SideSwipe guards are shifted to the side of the fork, where mtb forks actually take abuse. This results in a better-looking layout that’s more specific to the mountain bike application.
