Are you experiencing a slipping or sticking rear gear? No worries! These common issues can often be traced back to worn teeth on your cassette cogs. Thankfully, replacing the rear freewheel cassette or freehub can bring back the smooth shifting you love. This process involves a few simple steps: removing the wheelset, quick-release skewer or axle, and using specialized tools to swap out the cassette while ensuring it's torqued to the manufacturer's specs. Once we've got everything back together, a quick functionality check will have you back on the road, enjoying your ride in no time!
