????♂️ What it is
A 29” carbon rear MTB wheel designed for:
- XC racing
- marathon riding
- aggressive trail / down-country use
???? The rear wheel handles:
- power transfer
- braking loads
- most impacts
So durability + responsiveness matter even more here.
???? Core concept (same as front—but more critical)
Like the front, it uses HITOP compliance technology:
- allows controlled flex
- reduces harshness
???? But on the rear wheel this also:
- improves traction when climbing
- keeps the tyre in contact with the ground
⚙️ Key features explained
