Sure, get a new bike. I'll be 70 in a few weeks with too many bikes now, but if I get back into shape and start riding a lot of gravel routes on road trips here in the west, I'll be looking at a gravel-centric bike with bigger tires and disc brakes. I've got a Cannondale SuperX cyclocross bike that's about 10 years old, but I may want something with room for bigger tires. And e-shifting looks pretty sweet. Again, get yourself a new bike if you can find something appropriate for your needs.
