Expand gears on cross to make more gravel/adventure
Hi - Have 2016 Cube CrossRace SL with full Shimano Ultegra 36/46 and 11-28. I want to have more choice on gearing - add lower end - so can do more hilly/adventure gravel riding. Should I leave crankset untouched and just replace rear cassette? Recommendations for range to go to? 11 -?? ? Will I need to change arm? chain? Sorry to be dim,hope someone can help me at least understand enough to go to LBS. TIA.
looking into the +1
Could likely put a 34 little ring on the front, but that's only really half a gear smaller. anything lower would prob need a different chainset eg grx 30-46, which brings other possible complications.
