Specifications
CNC-machined aluminum extra-long glue-in insert for carbon forks with integrated top cap bolt anchor threads. This insert replaces the standard expansion plug and adds extra strength to the steering tube. It is 123mm long and 23.8mm in diameter, so it supports almost the top five inches of the steering tube and provides greater strength under the spacer stack. This was designed for ENVE Forks, so they will work on any Enve carbon road fork except the older 1.0 model which has a thinner wall steering tube. It will work on any carbon fork with the appropriate inside diameter. You must measure your own fork's steering tube ID. If your fork's steering tube inside diameter is less than 23.8mm, this insert will not work. If the ID is more than 25mm it will not work. We don't have data on all forks, so we don't know if it will work on your fork unless you measure.
Epoxy is not included
. We recommend using a two part epoxy such
J-B Weld® Plastic Bonder
.
**NOTE: Do not over torque the top cap bolt. Top cap must be tightened to a minimum torque to remove headset play, but no more. This is about 1 or 2 nm. Only tighten the top cap bolt while the stem pinch bolts are loose. Failure to follow the instructions will result in breaking the epoxy bond and you will have to start over.
*Watch the video for installation instructions.

Perfect Solution for Damaged Enve Steer Tube
I believe that I had over tighten the stem on the 1” carbon fiber enve steer tube which resulted in gouging and a cut in the tube. This high quality insert allowed for a perfect and safe repair and is a fraction of the cost of replacing the fork.

Old Army pensioneer
Having had four level lumbar fusion in 2014 and then fractured pelvis from motorcycle wreck in 2017 I have lost a ton of my forward flexion and needed to raise my bars. My 2004 65cm Strong has an Alpha Q Z-Pro fork so I knew about the strengthening inner sleeve concept for tall stack steer tubes. My custom Kelson is not as tall in the headtube and so when I put a longer steer tube Enve fork on it I knew I was going to need an inner sleeve. I purchased the Zinn sleeve. It arrived quickly, installation was a piece of cake, and now I have zero worries with 60mm of spacer stack on my bike.

Mr.
Installed this little gem in my full carbon fork's steerer tube. Perfect fit, and I feel much more confident that the tube won't fail. If I had other full carbon forks, I'd install this in them, too.
