I'm being offered a 12-27 or 11-28, the latter I am told will make climbing a little easier and the top gear a little faster.
There is a £20 difference between the two. I need to let them know this morning which I would like so they can crack on.
I would just go with whichever is the cheaper option, there's not that much difference between them. An extra £20 is almost enough to buy a new cassette anyway
