Yup today is the day! I’ve just been informed that Easton’s New Zealand distributor has received their shipment of Easton’s M1 upgrade kits and they should be available at your local Easton dealer from today onwards for FREE. If you didn’t pay attention when we posted the initial press release, the upgrade is for any Easton M1 Hub (Havoc, Haven, EA 90, EC 90 and 70) from 2011 and 2012 and early 2013. To get your upgrade kit you need to head in to your local shop with your qualifying rear wheel as they require the serial number of all affected wheels. I’ve been running the new bearing kit for a month now and the difference is like night and day, with absolutely zero play developing.


Every Easton M1-hub equipped rear mountain bike wheel will be shipped with an updated hub. This running change dramatically increases bearing durability and will be found on all EC90 XC, Haven Carbon, EC70 Trail, EA90 XC, Haven, EA90 XD and Havoc wheelsets.

Easton is also offering a Bearing Spacer Upgrade Kit to retrofit M1-equipped wheels currently in the field. The update kit contains a bearing spacer, a new set of bearings and a new locknut and will be available free of charge to qualifying Easton wheel owners.

The affected hubs can be identified by the hub model number on the rear hub. Affected hub models end in the number 1; for example, M1-121, M1-221 and M1-321.

New wheels that have the upgrade can be identified by a green dot label on the box. Upgraded rear wheels can also be identified by the locknut on the non-drive side of the hub. The new locknut has the word “TIGHTEN” printed on it.
