We dig Easton wheels. We really do. Unfortunately some of the older hubs were plagued with bearing issues after extended use. Today they introduced a hub upgrade kit for M1 rear hubs used in EC90 XC, EA90 XC, EC70 Trail, Haven, Haven Carbon, Havoc and EA90 XD wheels. The Bearing Spacer Kit will be available late February 2013 free of charge for existing M1 rear hubs and is included as a running change in all M1 hub-equipped rear wheels shipped after mid-February.

Get the full scoop from Easton Cycling Brand Manager Dain Zaffke in this vid:

Easton M1 rear hubs are used in EC90 XC, EA90 XC, EC70 Trail, Haven, Haven Carbon, Havoc and EA90XD wheels. The Bearing Spacer Kit consists of an internal bearing spacer, a new set of bearings, a new end cap and there are installation tools available as well. They will be available free of charge to retrofit existing M1 wheels and can be installed by Easton distributors, retailers, or competent home mechanics (that's you!). The Bearing Spacer will also be included as a running change to all M1 hubs starting mid-February 2013.

Need help determining if your wheels are do for the upgrade? Here's a tech bulletin describing what to look for. Request your upgrade kit here.

How do you do it? Scott Junker runs you through the operation in this video (or in this print version). Seems pretty simple, yeah? We've got a few set of hoops that could use the upgrade and plan to bang it out ourselves in the near future.

Hooray for improvements, especially when they're at no charge! Cheers Easton.

    Just wondering about the hub on my Easton EA90 XC 2012. On the hub I can read M1-220. According to http://www.eastoncycling.com these hubs can only be used in configuration 135x10mm QR, but mine is 142x12 through axle. I didn't modify anything, I got it from chainreactioncycles.com. Can I apply the upgrade kit? Thx!

    Hey Bono, you might be best off reaching out to Easton directly, though their customer service page or phone number. Cheers bud.

    Crap, my Havocs are 2012, but aren't compatible (from the serial # and lockring check anyway). What do I do to get the bearings that will last?

    Timbud, here are some tips on how to get the most performance and durability out of your rear wheel.

    Easton wheels can be ridden with good bearing performance for years, however this does require tightening the hub’s preload adjuster the proper amount if it comes loose. This is very simple to do with a single cone wrench—with the wheel on or off the bike. You should only have to do this after the initial break in period or as your bearings begin to wear over time.

    Some of the bearing durability issues come when the preload adjuster has been ridden loose for several rides which can damage the bearings and the axle. Over-tightening the adjuster can also damage the bearings.

    If you have M1-120 or M1-220 hubs and want to improve your bearing life you can either send your wheel to Easton for service or at home apply a light Loctite (MS222 preferred) to the threads of the bearing adjuster on the non-drive side of the hub. If your bearings or axle are already worn they should be replaced before the repair.

    Basically if your wheel is not compatible with the new Upgrade Kit, applying Loctite Threadlocker Blue 242 to your preload adjuster will keep your bearings rolling smoothly.

    BIg move on Easton's part. I run the Havoc USTs on my Nomad and have had no issues with these amazing wheels. Thanks to easton for ensuring the performance stays top level and good work to Vital for getting the word out.

    This is a Solid Easton! Be on the Lookout for my email for my wife's EA90XC's hubs.
