Description
BMX Race tire 28-451 ehk 20 x 1-1/8
120 TPI
Weight 245g
Dual compound
max pressure 85PSI
Threads Per Inch (TPI)
The number of threads that cross through one square inch of a single ply of the tire’s casing. Lower TPI (ex. 60 TPI) gives better puncture, cut and abrasion resistance but is heavier. Higher TPI (ex. 120 TPI) conforms better to the terrain, offering a smoother, more comfortable ride while reducing the weight of the tire. The trade off being higher TPI casings are more fragile compared to lower TPI casings.
DUAL COMPOUND
Two compounds used within the tread of select tires to offer lower rolling resistance and increased cornering grip.
