If you're upgrading from Shimano 10 speed to 11 speed this replacement hub will allow you to continue to use your Easton wheels. It's easy to swap hubs and the new 11 speed cassette works perfectly.
Well, Easton , makes the things a little bit different when it becomes about free hubs one hub for each brand (shimano, SRAM and campagnolo). In my case I use SRAM, so whe I bought my wheels Easton ec 90 sl, what a surprise I couldn't use my SRAM cassette with my wheels marked for shimano, but I found the solution with biketiresdirect.com
Purchased the freehub for my 2011 Campagnolo Chorus group.
With Easton you come to expect quality and this freehub body for Campagnolo 11 speed is no exception. The Campagnolo cassette fit perfectly onto the freehub body and due to the width of the 11 speed cassette there no need for a spacer. The fit into the R4 hub is a perfect and is the same as the 10 speed Sramshimano, which makes it easy to change between the 2 systems.
Right of the box the ball bearings are running freely and keep in mind they are standard ball bearings, non ceramic, however they are a great value at almost half the price of ceramic bearing version.
I can only recommend this freehub body.
The Easton R4 Freehub body works great. The problem is that the Easton EA90 wheels with the R4 hub are dished in such a way that I was unable to run them with the Campy 11 group. To get the rear stops set properly so that the chain would not jump down a cog the cage was too close to the spokes. I ended up selling the wheels.
I changed my groupset from Shimano to SRAM so I needed a compatible freehub body for my Easton wheels. Website provided great guidance and information. Als, great prices and fast shipping. Thank you Bike Tires Direct.com.
Easy install for my ec90tt wheelset couple of turns of the wrench and pow the Sram Free Body was off and I was ready to pop on the Campy free hub. Not too loud and quite light. I am super impressed, great overall product.
I was never happy with the hybrid dual purpose use of the original freehub. Shimano and Sram measure peaks and valleys of the cassette differently. Although both Shimano and Sram cassettes fit the stock freehub, there was a lot of slop and the freehub body tends to get chewed up. Search forums and you will find several threads of complaints. The Easton HA10E0906 red freehub is Shimano 10 speed specific and eliminated the slop. Cheap price to pay for correct and precise fit.
I have always appreciated the quality and durability of Easton products. Recently, I purchased a set of Easton EC90 wheels and have been very impressed with their performance. With less than 1,000 miles in the ceramic freehub bearings failed! I ordered the freehub body rather that just replacing the bearings because it was easier and more cost effective. Another nice thing about these wheels and the easy freehub exchange is the ability to flip quickly between Shimano and Campy-a real plus for me. I just hope this failure was a fluke- the jury is still out on ceramic bearings for me....
P.S. Love you guys.... You generally have what I need at a great price.... Appreciated....
