Frame Compatibility

The inserts are compatible with most frames.

However, due to the variation in frame and headset designs, there is a chance you will not able to run extremely low offsets. This can be an issue when running inserts such as -10mm in combination with a frame that has a large head tube outer diameter and a low stack height headset. If you have this issue, there are 2 ways to address it:

1. You can avoid running low offsets that will contact your frame. Refer to table below.

 

Offset (mm)  Maximum Head Tube Diameter (mm)
-10 61
-8 65
-6 69 

 

2. You can also extend the fork stanchions in the clamps. This method works very well with Boxxer forks due to the fork design - you will only need to raise the clamps a few millimeters. For the Fox 40, this method will require a greater increase due to the fork design. For this reason (and to accommodate 29ers), we have designed the upper Fox 40 clamp to have a some drop.


*Always check the full travel of your fork when running a new offset for the first time to ensure that there are no contact points between your fork and frame. Failure to adhere to these compatibility limits will void the warranty and can result in severe injury and death, as well as damage to your bicycle.
