Yes, the OneUp EDC Lite Tool, EDC Threadless Carrier, and EDC Threaded Carrier are compatible with Helm, depending on the length of your steerer tube after cutting. Refer to the EDC Fork Calculator & Compatibility page on OneUp's website for more information. Threading the steerer tube of your Helm to use the EDC Threaded Carrier will not void the warranty if you properly follow One Up's instructions.
