SRAM cassette doesn't fit on Novatec F172SB rear hub?

Hello! I just built a rear wheel using a Novatec F172SB rear hub and it seems that my SRAM PG cassette only fits until some notch comes in contact with it. I read that new Shimano freehubs are not really compatible with SRAM cassettes because of the higher notches. Is there any SRAM cassette that would fit this freehub or should I just buy a Shimano cassette?

Thanks in advance!

Google pictures suggest that hub has a Hyperglide (HG) hub. It is kind of standard since 95% of all bikes have that. both SRAM and Shimano make cassettes for that (as do other manufacturers like sunrace etc.).
If you look up the exact cassette number, you see what it is, but if you have hub and cassette in hand, you should be able to fit if it fits...
HG hub has an 11T minimum cog size.

You need to turn the cogs or spider in the right degree in relation to the hub splines. All the splines are different in width and distance to each other. The cassette only will fit one way unlike a crank for example. This is to make sure the shift ramps on the cogs are in proper relation to each other. Look at the teeth, some look like worn or oddly shaped, there is a reason for that to improve shifting.

If by new shimano hub you mean their newly released 11 and 12-speed, this isn't really available yet (Microspline) . But that will be a different shape. Same way SRAM had some new hub (xD). both of those new hubs support 10T cogs and are not compatible to each other or to HG hubs and cassettes.

Sram PG cassettes fit Shimano freehubs- i have them on a few Shimano branded hubs and also Shimano style freehubs. its all the same.

The Shimano 105, Ultegra and Dura Ace 10 sp cassettes all fit perfectly. The guys at the bike shop said they didn't see such a thing before. One guy at a bike shop said it was marketing crap.

Sounds like you have a 10sp deep spline freehub. I have a wheelset with a deep spline Novatech hub. No a SRAM will not fit. I don't believe 105 will fit, either. I'm pretty sure only Ultegra and DA had deep splines.

I thought that too when I saw the title of this thread since I made a thread years ago with the same kind of problem.
New cassette will not fit on old hub? Road bike
10s 105 does have the deep spines, it is tiagra 10s that they stopped doing that. The deep spline freehub thing died off a long time ago before I even made my thread. This is a modern 11 speed compatible hub so I'm confused unless he has the model number on the hub messed up.

Or it could just be a manufacture defect that shipped out with taller splines and nobody noticed before because as long as you are running shimano 105 or higher 10 speed cassettes it wouldn't matter since they are still made to fit that old out dated deep spline freehub.
