>>1068298Brakes and drivetrain are very important aspects of a bike, you did mention frame geomtry being different already. So I'll skip the taller head tube and shallow angle.
The wheels are roughly twice as wide as those avalible on a road bike. 700cx23 is the most common race tire size.
700cx28 is considered thin for a hybrid.
A 28 won't even fit most high end road bikes (they fit piece of shit road bikes like the giant defy or trek alpha because old people trying to look cool)
The forks are different and not interchangeable.
Most hybrids also ship with disc brakes at the consumer level.
Road bikes typically have dual pivot brakes because the UCI seems disc brakes to be a hazard in the peloton.
Hybrid bike wheels are also different. They typically don't ship with skewers at the low end, track but style through axles are the.norm.
The saddle and seat post are also setback at a different angle and saddles put comfort and foam thickness at a premium over power transfer
