I have a Scott S30 bike currently running a shimano 105 2x10 speed 50-34 crankset, shimano 105 10 speed front shifter and 10 speed cassete and chain. I have a new crank that i want to install, the shimano 105 5800 53-39 but it is 11 speed. I'd like to know if i can make it work with the rest of the bike. I will change cassete and chain anyways because they already need replacement. So i have some questions:
- Can i buy the same 10 speed cassette i used before?
- I use a 12-25 cassete now, can i upgrade to a 11-28 one or does this require a special rear derailleur?
- The chain can be the same 10 speed chain or should i buy a 11 speed one? I have read mixed opinions on this. Some say its fine with 10 speed other say its better with 11...
- Are this good cables for my bike? I need to replace them but i can't spend much http://www.bike24.com/1.php?content=8;navigation=2;product=21934
