'T' in Cassette Specification

[Distorted Vision]

I've always wondered what the T meant. Eg what is the difference between Shimano Ultegra CS-R8000 11-28 and 11-28T?

Teeth?

Teeth?

Still don't understand. What is the difference between a T and non-T version?

I don't think there's a difference, it is the same thing written two different ways. The T in cassettes and chainrings stands for teeth.

When I write, say, 28T I always mean 28 teeth.
But I don't sell cassettes, so that's pretty irrelevant

You can always ask them - but I think it's just a cockup at their end. The T just means teeth.

I suspect they decided to add the "t", and in that one case, rather than modifying the record, created a new one. And the old one (with old price) is still showing up on the website - but as OOS because they put all their stock onto the new catalogue number.

If "T" were to mean anything other than teeth, it would appear to have the entire CC membership confused.

11-28, 11-28t, 11-28T, 11-28 teeth (and any combination of upper and lower cases in case some smart alec picks up on that) mean exactly the same thing.

The difference in price between one cassette and another cassette would be if something is out of stock, or a different quality or brand or model of cassette, or a new model has come out, marketing stuff like that. But as far as those numbers go, they are they same thing.

Good observation though and i can see how this would be something to think about for anyone new to cassettes, especially considering the different standards we have in cycling (don't get me started on bottom brackets!).

It means "Ticky". Some cassettes are engineered to amplify the ticking noise from the freewheel.

Cassettes are silent!

It's the ruddy freehubs that go TICK TICK TICK.....
