11 Speed Shimano free hub body with 10 speed DA cassette

[Doncantador]

I have received my wheels from built. Built on Tune Mag/Mig 170/70 tubless rims Stan's 340 mode year is 2013 24/28 CX Ray spokes. As I mentioned 11speed freehub body. I haven't receive with it the spacer (1.8mm) in order to use my 10 speed cassette Dura Ace 28/11. Never the less I installed the 10 speed DA cassette with the 1mm spacer it comes with and there is no freedom at all but the ride is "heavy" feeling, it seems like it is very difficult to accelerate with the wheelset. I can compare it to my Zipp 404 tubular wheelset I have (almost the same weight with my current wheels around the 1300 gram for pair) but so much different...! I'm waiting for the 1.8mm spacer to arrive but I wonder if the lack of this spacer can be the cause of this "heavy" acceleration feeling or it has nothing to do with it and it is most probably the wheels alone. Ill love to hear your take on that.

Missing 0.8 mm of spacer shouldn't change the rolling resistance of the wheel but it will affect the chain line and rear derailleur indexing.

Check the dish of your new wheel and make sure it's not rubbing on the brake pads or the frame.
