FAT BIKE RIMS

CONTACT SURFACE ANALYSIS

contact-surface-analysisG

We have compared four different tire and rim set-ups, all inflated at similar pressures and all submitted to the same weight pressure. Tires have been coated with a marking solution and the imprint left on the ground after pressure was measured. Tests have been conducted in two steps, first with tires inflated to 6 psi, then with tires inflated to 10 psi.

CONCLUSIONS:
• Low pressure (6 PSI, appropriate for new, loose snow after regular and impor- tant snowfalls) : Combining a 4,7’’ tire with a 100mm wide rim offers a contact patch 38% larger than a 4’’ tire on a 80mm wide rim. Additionally, the pattern of the patch of the 4,7’’ tire has a wider shape, which means better floating and traction abilities.

• High pressure (10 PSI, appropriate for hard-packed snow, lack of precipitation) :
The 4,7’’ tire/100mm wide rim combo offers a contact patch only 26% larger than the 4’’ tire/80mm rim combo. Simply put, a 4,7’’ tire/100mm wide rim combo is the most efficient setup in soft snow conditions, with a contact patch clearly superior. On the other hand, in firm, packed snow conditions, the gap between the contact surfaces of a wide and a narrow rim is less significative, which minimises the unwanted friction inherent in a wide rim set-up.

AL100:
Fat bike 100mm Aluminum rim
TRACTION AND STABILITY AT THE RIGHT PRICE.

This extra-wide 100mm-wide aluminum rim is designed to provide traction in the worst winter conditions. Stretched at a width of 100mm, any tire will see its contact surface widened significantly, which means a very stable ride and all the traction needed on new snow. In soft conditions, you’ll be pedaling while the other will be pushing.

AL90:
Fat bike 90mm Aluminum rim
LIGHTNESS AND SPEED AT AN AFFORDABLE PRICE.

Slightly wider than the average at 90mm, this aluminum rim extends the contact patch of the tire, giving that extra traction needed on deep, soft surfaces while staying fast on hardpacked soil.
