Can a hybrid bike's stem be slammed to make it nearly as fast and powerful as a road or cyclocross bike?
More aggressive positions are thought to improve power transfer. That means a better workout when doing HIIT.
With a lower position, we tend to be more aerodynamic. People often find that road bikes are a few km/h faster than hybrid bikes. A cyclocross bike isn't much slower than a road bike. It must be mostly aerodynamics that played a role.
Someone might want to do this because it's cheaper and prefers handlebar mounted shifters. A pair of STI shifters can cost a few hundreds of dollars while equivalent speed shifters may cost only one third that for non-drop style handlebars.
According to the following article, it looks like we need to select a stem with an angle and length that makes the handlebar height 5 to 10 cm below that of the saddle. https://www.mec.ca/en/explore/fitting-your-bike
If I use the right stem so that the reach and handlebar heights are similar to those of road bikes, would it work? The stem may need to be longer than you can find in stores because there are no hoods to extend the reach.
