Hi, i recently bought a raleigh airlite road bike as a starter to get into the sport. right from the start i wasnt happy with the rear derailler, changes where sluggish and unreliable. i have fully adjusted it to run as best it can but i am at the point where i would like to maybe upgrade it. im a student and do not have alot of money to spend so i have been looking at the shimano sora range. The rear cassette is 7 speed the current derailer is a RD-TY18 (which seems to be non existant on the shimano website!) and the shifter is a bar mounted 7 speed SIS. Im wondering if its as simple as replacing the the rear derailler? i will probably upgrade to the sora STI shifters soon.
Any help will be greatly apprechiated!
