This is an absolutely crazy idea. Would you buy a bike with no ability to change seat height, or a helmet with strap length adjustment?

Buying a bike that requires no spacer is buying a bike that you can NEVER lower the bars, no matter what happens to your fitness and flexibility.


AND, some fork steerer failures came from not having a spacer to distribute flex between the headset and stem.


Ideally, a bike that is perfectly fit would have 10-20mm of spacers so you can still lower the stem and have some spacer for steerer health.
