Removable 26.0 Clamp Is the handlebar clamp diameter. 26.0 is a common drop bar size.
Threadless 1.125" Is the clamp onto the steerer tube of the fork and is common for both road and MTB.

- Is my extra flat handlebar indeed a 25.4mm or is it really a 25.2mm? This is where everything starts. Assume that it's 25.4
- Do I really need to get new brake cables to convert from dropbar brakes to flatbar brakes? If so any recommendations? Yes. Get decent ones which come packaged with inners and outers. Make sure the inners have sideways cylinder ends for MTB brakes.
- So I really need to by a new stem (see dimensions above)? Get the 25.4 stem. You'll be happy you did.
- Any suggestions on grips? Comfort or control? Ergons (as mentioned) for comfort, Grippy narrower cylindrical grips for control.
- Are there conversion bundles I can get that has all of the above? Not that I've heard of.
