Whats the most effective way to maintain the delicate balance between chain wear and cassette degradation on a mixed terrain bike, considering the constant switching between road and dirt, and how do you reconcile the conflicting demands of minimizing wear on the drivetrain with the need for optimal gear range and crisp shifting, particularly when it comes to the often-overlooked but crucial interface between the chainrings and cassette, and are there any specific cleaning and maintenance protocols that can help mitigate the inevitable trade-offs between durability and performance in this context, or is it simply a matter of accepting that mixed terrain bikes are inherently compromised and that we just have to live with the consequences of trying to have our cake and eat it too?
