Why We offer 26" Wheels For The Road?
-
26” wheels are stronger than 700c wheels. Since tandems carry
more weight than single bikes, they are ideal for running 26” wheels.
-
Disc brakes are stronger with 26” wheels. The same size rotor will have more leverage to stop the bike with the smaller wheel.
-
26” wheels have less inertia and weigh less than a comparably
designed 700c wheel. Therefore, they accelerate more quickly, climb better
and are fast.
-
26” wheels offer a versatile tire selection, from narrow
road tires to aggressive mountain bike tires.
