105 10spd cassette

Not exactly a mechanical problem but just wondering about this - I recently changed from an old Suntour RD, 7speed cassette set up to Shimano 105 long cage RD & 10 Speed cassette. Im not sure exactly what speed my old one was on the big cog, but size wise it's definitely smaller/the same size as my new 28T 105, yet the new 105 feels sort of harder to pedal and I'm not sure why - is it something to do with the change to more modern stuff? It's a 53 on the front and used to spin really well but now I don't really know if I could climb on this set up (also haven't cycled in a month, may be a contributing factor

The age of the sprockets don't matter, if they are the same size they will feel exactly the same. The answer is the bit I've highlighted in bold.

Haha yeah I thought it would be, a combination of that and an eerie smoothness to having a brand new cassette.
