I ride a 7 speed bike. 1st bike Shimano Altus 12-32 T Casette 2017 Raleigh Retroglide IE. On my Second Bike Blix Aveny 48T Chainring, and Shimano Acera 14-28 T Casette. The mechanic at a LBS stated that my chain was .75 worn. What drive train changes would you recommend? Chain and Casette for the second bike? My rides are on the street and MUS Trails. Cherry Creek Trail in Denver. Any recommendations are appreciated. Thank You. I do ride in the drizzle, no mud. I've included my commute video.
