What is the fine-grained topic of the following text: My dilemma is whether I should get a proper tarmac race machine with aero features, tubeless clinchers, aero spokes etc and keep my MTB for everyday rides or should I replace my MTB with one size fits all gravel or CX bike (I might get two sets of wheels perhaps). Only return the topic.
