Question about these Easton EC90 SL clinchers

Hi,

I was thinking about picking these wheels up used for my bike with an older 10sp ultegra group. This set comes with a 10sp cassette so I know they will work now. But if I ever upgrade my bike I know there's pretty much no such thing as 10sp anymore - will this EC90 rear wheel take a 11sp shimano cassette as well? Not what year of manufacture these wheels are but they look newer dont they? They are clincher/rim brake. Thanks

I believe there are Shimano HG 11-34 11 speed cassettes that will work on 10 speed freehubs.

Are these genuine Easton wheels?

AFAIK they will not take an 11sp freehub,

but if you upgrade your bike there will hardly be rim brake as well so no biggie.

Additionally, they may have a freehub that will take Shimano but not SRAM cassette.

As far as I can tell yes. Does something about the pic tell you they aren't?

I don't think so but I believe that the Easton's use a Chinese hub and you can get an 11 speed freehub for it.

I had a set on my Madone 4.6, The constantly went out of true and have to be fixed. On the 3rd time in a year the wheel was sent to Easton and after 4 months I got it back. They replaced all the spokes and nipples. One month later it was out of true and again sent back to Easton.

In the meantime i purchased a new bike and put a set of Zipp 303s on.

I sold the Madone with the original wheels and sold the Eastons seperately.

BTW.. 26,000 miles on the Zipps and not a single problem.

I can’t directly answer the question but I suspect Easton makes an 11 speed cassette body you can swap out. Check with them.

Also, there should be ample 10s components (especially wear items like chains and cassettes) indefinitely available, even if you have to seek out NOS items on EBay etc., so factor that in. I run 10s on all my bikes and for cross-compatibility reasons will not likely go 11s ever. Next upgrade, if it happens, will be in a few years and will be 12s for sure or maybe even lucky 13.

I find that 10 speed groups run more quietly than the 11's.

FWIW, this is correct. The large 34T overhangs the freehub so this 11 speed cassette will fit a 10 speed freehub. Old thread, I expect OP has made a decision....

I have a set of those (tubular), a set of EA70s, and had a set of EC90s that the rims wore out.

They've all stayed true, but the older ones have a side-play adjustment nut that doesn't keep it's position. An updated part is available from Easton.

Odd because i've been looking for a Sram Red or Force compact crank for my son's Madone 6.2. He no longer races adn the standard chainrings are just not needed.

You can find these cranksets used all day. Also you could use an 11 speed version with no ill effects afaik.
