Selling the components from a Mad4One Race ISIS Light 26" (24" IUF). Everything is included except the frame, which I will keep for use with a 24" × 2" setup and a Mad4One Super Comfy saddle.
This is one of the fastest and most competitive setups available for track racing and 10 km road racing, while still complying with the standard 24" racing class through the use of a 26" wheel with a narrow racing tire.
With Unicon 22 in Austria approaching, this is a great opportunity to build a high-end racing unicycle at a fraction of the cost of buying new.
Included components:
-
Mad4One ISIS Hub ERGAL, 36 holes
-
85 mm hub spacing
-
Mad4One Agile Race cranks
-
Mad4One Handle Saddle M (Muni & Track Race version), narrow cushion
-
DT Swiss 535 26" rim
-
Complete 26" wheel (24" IUF compliant)
Condition
-
Hub and rim are practically new and in excellent condition.
-
Saddle, cranks, and pedals have seen a bit more use, but remain in very good condition and are fully race-ready.
Price
€290 for all components.
A new Mad4One Race frame costs approximately €176 including typical European VAT, meaning that for around €466 total you can build a complete high-end racing unicycle. The equivalent configuration would cost approximately €662 including typical European VAT when purchased new.
This may also be attractive for riders who already own a Mad4One Powersquare Race frame with a standard 24" × 2" setup and want a faster, more race-oriented wheel configuration using a narrow 26" racing wheel while remaining within the 24" IUF class.
Location & Delivery
Located in Sandefjord, Norway.
I will be attending Unicon 22 in Austria and arriving on July 29. I can bring the components with me and hand them over in person at Unicon, which will likely be the easiest and most cost-effective option for European buyers.
Feel free to contact me with any questions or if you would like additional photos.
