I am sorry what was a question I had, developed into this.
I enquired into the 9 speed freewheel as I had not been able to find a wheelset with wide rims that are rim brake capable as I was thinking about running 35 to 38 wide tires. I didn't think I could run tires that wide on narrow road bike rims. My 2016 Diamondback Insight 1 has 135mm spacing, it currently has a 3x8 drivetrain.
If I can run wide tires on a road bike rim, I would probably go to a 10 or 11 speed drivetrain. I do use all my gears, like having closer spacing so I didn't have such big jumps when changing gears and I do need to have a bigger granny gear as I get older and don't have the legs I used to and have no interest in a ebike.
As far as just getting a new bike,almost everything is going to a 1x system these days, which I would not prefer, rather have a front derrailer either a 2x or 3x. I am not crazy about a lot of the current bikes that are available plus my bike is in perfect condition.
I appreciate everyone's help but apologize for causing such a problem.
