🔧 What Is the Koova 75T Hub Structure — And Why Does It Matter?
When it comes to mountain biking, the rear hub isn't just a component — it's the core of your bike's power transfer system. That’s why the Koova 75T ratchet hub is making waves in the MTB world. With strong engagement, rapid response, and boost compatibility, it's built for serious riders who demand performance and reliability.
🌀 What Does “75T” Mean in a Bike Hub?
“75T” refers to 75 teeth on the ratchet ring inside the freehub mechanism. The more teeth, the quicker the engagement between pedal input and wheel movement.
With 75 teeth:
-
Each engagement happens every 4.8 degrees of crank movement
-
Power is transferred almost instantly
-
You'll feel faster reaction times when climbing, sprinting, or navigating technical terrain
