What are these hubs? They aren't what I was told they were

[mattyfatty]

So I bought these wheels on Ebay and it said they were 10spd Shimano. But my 10spd Shimano cassette does not fit. I took it to my LBS and they didn't know because they aren't an Easton dealer.

The wheels are Easton EA90 SLX.

Here are pictures of the hub

I had a pair (still have other Eastons). It took a lot of research to find it out, but I thnk they are Shimano compatible but with special splines. WIll try and find the page that explained it

not read in full, but may help

Unless of course you actually have a campag hub....

It's definitely shimano. I think I've found the source of the problem. These are R4SL hubs which are red. Apparently the red ones only fit dura ace 7800/7900... great! Wish I'd known that before haha.

I had red Easton ones that used Ultegra or lower... Do double check

I had a Shimano wheelset with a Shimano only 10 speed hub, it looked a bit like the one in the OP. It worked with a CS5700 (105 10 speed) cassette.

As far as I know all Shimano hub/Cassettes of the same speed should be interchangeable .....

I think so as well. They should also take Sram which are interchangeable.

Having taken a better look the pattern is not like the Shimano hubs I've seen. Also the splines are quite chewed-up which makes fitting the cassette difficult. There should also be one spline wider than the others too ....

Campag and Shimano splines completely different. Campag have 8 deep splines, Shimano 9, shallower with the fat spline.

I must stress the Shimano 10spd is ONLY compatible with Shimano 10 speed cassettes, the splines are deeper and look different to the regular shimano freehub body.

You probably have an alloy freehub with Shimano deep splines. Once upon a time Shimano decided to make some higher group freehubs lighter, so they used alloy rather than steel, but to stop the sprockets chewing into alloy splines they made the splines deeper (for corresponding deeper slots in the sprockets). For profile see this, Sheldon also discussed them here.

@the_mikey and @RecordAceFromNew ... thanks! I've learnt something today!
