Cassettes

I'm currently using a Tiagra 12-28 cassette, it's the second one I've had on the bike since new and it was bought simply as a like for like replacement by the LBS in my hometown.

Now I'm looking to get a new cassette that I'd fit myself I'm unsure whether to get a 105 11-28 or the Tiagra. Both are reasonably cheap on Wiggle and the price isn't really an influence since the difference is so small.

So the question really is, is there a noticeable difference between the two? Everything else is 105 so from a matching perspective I am leaning to that, though it's not really a big deal as I'm fitting 6800 brakes at the moment in any case.

I have a tiagra cassette 12-28 but bought a new set of wheels and went for a 105 12-27. I think 11-28 spread was a bit wide, I rarely used 12t so defo did not need the 11t gear.

I've only used the 12t on a few descents, the 28t is only really used when I'm at my parents where it's a good bit hillier than where I live or when I'm not feeling good!

If you are spinning out on the 12 then get the 11-28 105, but if not I would not bother with the 11.

I would go for the 12-27 105 personally unless you really need the 28.

You just have to make sure you have the highest and lowest gears you need and personally I would always upgrade quality when replacing worn parts if there is not much difference in the cost.

There will be something like 50g weight difference, and probably no difference in shifting or durability.
