Easton announces bearing spacer upgrade kit for M1 mountain bike hubs

News Detail Image

Beginning in March 2013, 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 or in your shop’s inventory. 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.

To identify if your wheel is compatible with the Bearing Spacer Upgrade Kit:

Look for the model number on your rear hub. If your hub model ends in the number 1, it is compatible. Examples of compatible hubs: M1-121, M1-221, M1-321.

Updated wheels can be identified in two ways:

Upgraded rear wheels are shipped in a box with a green dot on the outside label. Green dot = upgraded hub.

Upgraded rear wheels can also be identified by the locknut on the non-drive side of the hub. The new locknut features the word “TIGHTEN”. New “TIGHTEN” locknut = upgraded hub.

Adding the Bearing Spacer Upgrade Kit to M1 rear hubs dramatically improves bearing durability and eliminates hub play associated with an unthreading preload adjuster. The Bearing Spacer Kit can be installed by Easton distributors, retailers or competent home mechanics. Please note: All parts of the update kit need to be used together for the kit to work.

Two separate items will be available for shipping beginning late-February 2013.

1) M1 BEARING SPACER / BEARING KIT – Part# 8004010 (Shops need one per rear hub)

2) BEARING DRIFT KIT 15 M1 BEARING SPACER – Part# 8004015 (This is the tool kit. Shops need just
one of these).
