I currently have an ultegra cassette in 12-23 and am looking to switch it out for a 12-25 or a 12-27 (both also ultegra and both to make it easier on steep hills in the Colorado Rocky Mountains). I need a couple tools to get the cassette on and off, is there anything else that I need to be aware of? Will I need to adjust the chain length?
Or is it as simple as changing the cassette with another one and going for a ride?
Thanks for any input.
