PG-1050 cassette spacers - all should be even spacing?

Anonymous

Stupid question I'm sure but re-fitting a PG-1050 cassette onto my wheel (went off for a fix) and I'm sure I've got all the spacers right, but I get a narrower gap between one pair of cogs than the rest. I'm sure this isn't right, but just checking.

What I've got is (on a 12-36 cassette), the spider plus 4 spacers of what I'd call normal size but 1 spacer half that thickness, plus the remaining cogs & lockring.

Wherever I put the half width spacer it seems it will give me a smaller gap between those cogs.

Am I doing something wrong or have I got the wrong spacer or something? This was as supplied and seems there's a limited fit to get the lockring on and thought maybe they'd done something deliberately to squeeze it on there, it being 10 speed. Wheel is a CB Iodine with corresponding CB hub. There are a bunch of washers between hub and cassette also which seem necessary to ensure the cassette doesn't hit the hub.

Yes all the spacers in the cassette should be the same giving you equal spacing on all sprockets, maybe you have one mixed up with the hub washers.

Stuck it on as I think it was and it's not shifting right at all, so it's wrong. Actually the LBS had the cassette in store for me and maybe they've given it back with something duff.

The hub washers/spacers are really tiny thin things, about 4 of them and they seem necessary to stop it striking the hub. Looks like I've got a wrong spacer in there somehow. Need to enquire.

Guessing you got your wheel back.

Why don't you just look up the instructions on SRAMs site? Oh, thats right, SRAM don't know how to write technical documents, I forgot.

Yeah, tried to find just a simple "this is how the cassette fits together" document, but couldn't. Or at least I can't navigate their site.

It might be buried somewhere on one of those 10 meter wide 100 languages diagram/instruction things that doesn't make sense even in the English part if you can find it.

Back to the only other cassette I've got for the moment which is a 9 speed. Actually runs really nice on the 2x10 X0 kit, just have to watch out for that 10th shift!.

There is 2 spacers you need to put between the cogs that are on the carrier and the first loose cog on my SRAM 10 speed cassette. Cant remember what the model number is though and I cant have a look till sunday but it might be worth checking.

If the 10 speeds are like the 9 speeds, the cheaper ones are more of a complete unit with a few loose cogs and the more expensive ones come in more bits and use more spacers. In my case with the 1050 it just turns out for some reason one of these spacers is not thick enough. Maybe a slip up somewhere shop or supplier.

Anyway, 9 speed went on to get a ride in, realised half way though that BB spacers must be the same size and I've got spares of them, so just used one of them and problem solved.
