Shimano dura Ace 7800 free hub
Hi Folks, I have just bought a second hand pair of Fulcrum Racing Zero's which appears to have a 7800 Dura ace free wheel. Consequently the SRAM cassette I have just bought won't fit and neither will standard shimano! Its definately shamano not Campag. Will i have to buy a dura Ace cassette now and if so will it be compatible with the rest of the drive train which is ultegra which I am running with a SRAM chain which i find better than Shimano's . I got the wheels for a really good price and they ar ein superb condition but I am loathe to spend £160 for a dura ace cassette. Otherwise I guess its rebuild the wheel onto an shimano/SRAM compatible hub.
All advice gratefully received

SRAM fits Shimano. If a SRAM cassette won't fit, it isn't a Shimano freehub. It can only be fitted one way though so make sure you are fitting it correctly.
If it isn't fitting, it will be a Campagnolo freehub -Shimano ones are available so just go buy one of those.0 -
I have a spare shimano pattern freehub for fulcrum zero wheels which definitely fits ultegra 10 speed cassettes. not sure about sram, but the ultegra casettes are about £45Colnago Addict!0

Fulcrum wheels are supplied with either of the following freehub bodies:
Campag 9/10/11 speed
Shimano/SRAM 8/9/10 speed
Shimano 10 speed only
If it's definitely a Shimano pattern but a SRAM cassette won't fit, it's likely to be the Shimano 10 speed only freehub.
It's odd that you say a standard Shimano cassette won't fit. All 10 speed Shimano cassettes are an identical fitment, so if an Ultegra or 105 won't fit then a Dura-Ace won't either.
Can you post a picture of the freehub?Alex0 -
Cheers Guys I can only think its a Campag hub despite my 'mate' who sold them to me said it was shimano. I have checked it against a shimano freewheel on a spare set of mavic kysiriums and theyare soooo different. My fault I should have checked more closely but then againnvvendor is a mate. I will be seeing him tomorrow to sort out.
Mrdsgs, You mentioned you had a spare Fulcrum zero shimano hub. Is it red by any chance? If so I am interested.
Cheers Spagforth :evil: :?0 -
no, the freehubs are not red, they are a dull steel/metal colour whereas the campag one are shiny alloy, much deeper splines and one distinctive stepped L shaped spline/grove.
Campagnolo make fulcrum wheels.
The distinctive feature of the axle circumference is that is is not fully round. Similarly the inside of the freehub axle hole has a couple of flat spots so you have to line them up when fitting and removing.
My zeros are, I think 2 years old and the spare freehub is boxed and other than checking it fitted it has not been used. It will definitely take an ultegra 10 speed cassette but I cannot guarantee it will fit your rear hub without knowing the age of your wheels.
th simplest thing to do is to take your freehub off and post a photo of the underside of it, and the side view. I would then be able to confirm compatibility.Colnago Addict!0 -
oh by the way, yes the HUB is red but we are taking about just the replaceable bit that the cassette fits onto (the freehub) that is what I have a spare of. Swapping them is very easy.Colnago Addict!0
