Easton EA90 RT Wheelset - Dura-Ace Freehub

Improved ride quality, better cornering traction, fewer flats; these are just a few reasons to ride road tubeless. Easton engineers recognized these benefits and saw an opportunity to make a better road tubeless wheel system using some of the technology that’s made Easton’s UST mountain wheels category leaders.

The EA90 RT wheelset utilizes a proprietary rim design that holds a road tubeless bead securely even at pressures less than 100psi and holds an airtight seal between the rim and tire. A 17.5-milimeter internal rim width provides an improved tire profile for added stability and even better flat resistance. We didn’t skimp on details with the road tubeless: The wheels rely on our sealed cartridge bearing R4 hubs, alloy freewheel and Sapim stainless spokes. As with all Easton wheels, the EA90 RT is entirely hand-built and acoustically tuned so it stays straight and true longer.

Rated 5 out of 5 by 3 reviewers.
Rated 5 out of 5 by Great wheels at great price!!! I bought these wheels in November 2013 to date I have done on them 3,600 miles. In the wet British conditions. I'm 79 kg so on the heavy side. No issues whatsoever, No broken spokes, no cracked rims. With skewers they are 1550 grams. They are stiff and rolling smooth. In the description it says DuraAce freehub, but you can easily fit Ultegra cassette I did not try 105 but it may also fit. 07 September 2014
Rated 5 out of 5 by хлипкий барабан Колеса отличные легкие катят хорошо, но есть небольшое неудобство барабан сделан из алюминия и при использовании бюджетных кассет из стали он начинает изнашиваться образуются зазубрены. лечение это использование дорогих кассет верхнего уровня. 28 August 2014
Rated 5 out of 5 by Great value at the sale price The wheels arrived very well packaged with no chance of damage. Installing a pair of Schwalbe One Tubeless 622-23 tyres with Stans fluid took less than 10 minutes each - no tools needed. I did use a compressor to do the initial inflation and the tyres seated immediately and hold pressure perfectly. The dura-ace freehub has stepped splines, longer for the bigger gears but is fully compatible with my ultegra 6700 series cassettes - no spacer needed. On the road the wheels run very smoothly and at 90 PSI give a compliant ride whilst rolling very easily. Time will tell how well the wheels last but first impressions are very positive. 11 August 2014

Answer: 
The 'Dura-Ace freehub' has higher splines than a conventional multi-speed Shimano freehub, and is therefore only compatible with the following cassettes:

Ultegra 6700 (10sp)
Dura Ace 7800 (10sp)
Dura Ace 7900 (10sp)

It is not compatible with the new 6800 or 9000 series 11sp cassettes.

Answer: 
Check the depth of the slots that fit on the freehub on the small sprockets compared to the biggest. If they are the same then the answer is no. If the bigger sprockets have deeper slots then you should be OK. In any case Ultegra 6700 cassettes fit perfectly and are not too expensive.

Answer: 
No, the hub has stepped splines which are longer for the bigger gears. Also it does not need the 1mm spacer with a 10-speed cassette so will be too short for 9 speed

Answer: 
The freehub on this wheel is for specific Shimano cassettes only compatible with the Shimano Dura Ace 7800 and Ultegra 6600 cassettes.

Changing the freehub would be an option but would have to be sourced directly from Easton as we do not stock such spares

Will these wheels fit my Shimano XT M771 10 speed (11-34) cassette?

I recently changed my cassette as I do loads of hills and therefore not the run of the mill cassette you would find on a road bike.

Answers

Answer: 
The EA90 RT (Road Tubeless) wheels run a sealed clincher rim so work fine with both a traditional clincher tire and tube setup, or a tubeless tire setup.
