OKO´s Magic Milk Hi-Fibre Bicycle Tyre Sealant assists a tubeless-ready tire to bond to a rim strip fitted inside the rim of a bicycle wheel.
It also coats the inside of the bicycle tire, making it ready to seal punctures instantly with a negligible loss of air pressure:
and it assists with filling the miniature holes that are present in the sidewalls of many tubeless-ready tires.
The tire sealant remains inside the tire so it is able to seal multiple punctures allowing the tires to remain fully operational for longer.
This latex-based ´milk´ sealant will dry out and require topping up to create a new active layer of sealant:
but the active life of this sealant is longer than competing brands (3-9 months depending on local temperatures).
Recommended dose is 30-120ml per tyre in most road to mountain to downhill bikes, depending on size.
RECOMMENDED FOR.
Road race tires:
handles high pressures.
Downhill low pressure tires.
MTB/XCO tires.
NOT RECOMMENDED FOR.
Not designed for use in tires with inner tubes:
for these the OKO ´Puncture Free´ product is capable of sealing bigger puncture holes and will last for the life of the tire.
