Im looking to get a new cassette for my bike, mine is looking a bit worn.
Just looking for advice on the range.... Im thinking 12-27 to give me the full range. Prob going to get the Shimano 105.
What does anyone think?
Also, I need a new chain.... any suggestions or should I just stick with Shimano 105 for that too?

I run an 11-21 on the TT Bike when its not a hilly course... on a hilly course I will switch to a 11-23 or 25 depending on the severity of the hills.
Ill always use an 11t though!:)
You might get away with a 25 and the only alteration is to lengthen the chain
The reason I ask is that Im buying some new wheels and need a new cassette (as my old cassette is worn and Im leaving on my 'Turbo trainer wheel/tyre setup') to fit to them, Im currently running 12-27, so thats why I decided on this to stick with it.
If I did go down to 12-25, would I need to shorten the chain? Change any of the components?
Treefrog, you are a fountain of bike maintenance knowledge so please impart if you will. No curses this time though.
Dunno about the mysteries of chain shortening but I guess it will be bloody obvious if you need to do this.
You mentioned getting a 105 or Ultegra cassette and a new chain... are you currently on a 10-speed set-up? I think there may be compatibility probs between 9 and 10 speed, so you couldn't bung a 105/Ulty/Dura cassette and chain on a bike with a Tiagra/Sora chainset. Probably.
Im on a 10-speed (old) Ultegra set-up so assuming a 10-speed 105 or Ultegra will work with it fine.
Thanks
And old 10 speed and new should mix fine
Seems when an old chain stretches with age, it wears the cassette differently to when its new, so swapping either one will mean the they will be out of sync with each other slightly. And thats when you get that annoying slipping when you apply a little extra force.
Having just finished cleaning the rear cassette and chain I am now intrigued. cheers for this.
I have a 12/25 on the rear and a 53/39 at the front. When I am on the small front ring and 12 or 13 at the back, this feels harder to pedal than when I am on the big ring and either 25 or 23 ring on the back. Is this right?
