After looking around, I was offered a test bike (500km)Specialized Roubaix SL4 expert UI2 2013 for 2500$. Should I jump on it ? Im a little unsure about the maintenance cost. If something happens, I believe its pretty expensive to replace Ultegra Di2 components
Is there a difference with a test bike and a non test bike ?
I would like to know also I can replace the cassette (11-28) for something like a 11-32. Where I live, ive got some big hills. 20% on average with some 25-30%.
Thank you.
Wow, I need to ride these hills.
2500 is a good deal for that bike. Shimano components are reliable, i would not worry about maintenance cost.
