3RD PARTY LABORATORY TESTS
WHEEL ENERGY LABORATORY, NASTOLA, FINLAND – USING EXTREME TEST METHODS WITH STATE OF THE ART TEST DEVISES.
ROLLING RESISTANCE DEVISE – MEASURES MOMENT OF INERTIA AND ROTATING FRICTION IN WATTS
- 1200mm rotating drum with diamond plate surface
- Drum speed 0 to 15 mph
- Load 110lbs
- Coast testing on paved road with slight up hill – no wind – no chain – no brakes
- All tests using same type Alloy rim (28mm inner width), same type 27.5×2.50 tire, all 25 psi TLR with 4oz sealant.
Using foam insert, requires slightly more effort to get out of the gate. Once at speed the watts are hardly measurable. Coast down test proved the biggest benefit and mirrored our test rider comments “foam insert help carry momentum thru corners and over rough terrain”.
GUILLOTINE DEVISE – MEASURE SIDEWALL STRENGTH AND PINCH FLAT DEVISE:
All tests using same type Alloy rim (28mm inner width), same type 27.5×2.50 tire, all 25 psi TLR with 4oz sealant and 30 lb drop weight:
Assembly without foam insert only managed two light hits before flatting. Assembly with foam insert took several hits at max height before losing air; allowing 20% higher impact force.
Foam Insert System – 28″ drop
Foam Insert System – 30″ drop
Foam Insert System – 32″ drop
