I plan to spend no more than around $450 for a hybrid/comfort bike to use on local level and hilly pavement which is mostly bumpy, no more than 10 miles per average ride. I'm 165lb., 6'1'' and will continue to use my old Motobecane road bike for those well-paved trails at a distance from home.
Given these circumstances, I'd appreciate any opinions about the relative negatives or positives of the Shimano Altus, Acera, and Alivo rear derailleurs which seem to be on most Trek and Giant bikes in my price range. Does it make any difference if it's a SRAM X.7(on the Trek 7300)?
Thank you in advance to all those who take the time to read this and respond.
