As stated above, the frame has already the attack for the disc brake and the Mad4One ISIS Disc hub. Have you in mind to mount your HandleSaddle laterally? In this case a brake system with an openable brake clamp is the right choice.​
The alloy used, AL7005, is of high quality and is in 17 different colors anodized. You have simply to choose the one you prefer. The Mad4One frame has double Disc Brake mounting tabs and double cable holder. The most critical point of the unicycle frames (both shapes, square and round) is the junction between seat tube and crown. This MAD frame has a double butted reinforcement seat-tube that makes it one of the strongest.

The Vee Speedster 27.5x2.80 makes the difference. The Speedster was designed for high speed and minimal rolling resistance on hardpack and paved terrain. Its honeycomb center tread provides minimal rolling resistance and unbelievably long tread life and traction. This design provides excellent grip in wet or dry conditions. Slightly larger diamond shaped side knobs enhance cornering traction. And, with its large volume casing you’ll feel like you’re floating on air.


Excellent quality, in plastic with a large sole, very robust however without metallic Pins.


MAD4ONE, version COMFORT, is ideal for Mountain Unicycle-Road, as well as Hockey and Basket. It has been designed for beginners through experts. Contrary to the traditional ones, this saddle comes with a gentle curve to reduce front pressure. Very good price/performance ratio. The integrated handle provides high comfort (no hole, more security and more space for the fingers)​.



Leg length: 74 cm min. (with cranks 138mm and saddle Mad4One Comfort)
