Formula Light tyres 25mm 265g (verified)
The natural latex lining is retained to improve comfort and reduce rolling resistance.
The new tyres measure 25mm on wide rims (19mm internal width) ! Unlike most brands IRC know wide rims offer the best performance so size the tyres for these rims.
Compared to the RBCC tyre grip it has a bit lower but rolling resistance is lower also. Durability is still decent but as the casing is lighter, so is not as resistant to punctures or sidewall damage as its sister tyres. This is a racing tyre for better roads.
Why use tubeless tyres?
