Rear Shock

This allows for quicker riding on rough roads and trails. In conclusion, to increase your riding experience, get a bike with a rear shock if possible.
Wheels
The wheels on R.X750 Ultra are the 29″ carbon type. Having 29″ wheels means that you need less fork travel, leading to a reduction of the pedal bob effect. However, if you’re not a tall person, you might find it difficult to adapt to this wheel size.
Brakes
