Shimano Ultegra R8000

I purchased the 11-34 Ultegra R8000 cassette from Mantel to replace my current Ultegra 11-32 cassette. Good service and quick delivery. I do a fair bit of hill climbing and as I get older, I needed a little more help. I was concerned at first thinking that the gear ratios may be difficult to get use to. To be fair it is brilliant I love the ratios - the 30 tooth gear is ideal for most hills, saving the 34 tooth ratio for that really tough climb, or when I'm fading!
