The Tufo technology in this model
Standard puncture protectionAn extra layer of rubberised casing under the tread: a barrier sufficient against most punctures, without hurting efficiency.
SPC Silica compoundTufo's reference road compound: 66 Shore A, a blend of natural and synthetic rubbers loaded with activated silica, for wet grip and low rolling resistance.
Carbon Black compoundThe training compound, proven over the years: high carbon-black content, high mileage, cut resistance.
Rubber puncture stripA layer of rubber laid under the tread: whatever passes through the rubber stops there before reaching the casing. It adds to the model's puncture barrier, it does not replace it. Tufo calls it the “protective rubber ply”.
S3 Lite et S3 Road, in a few words
What it does
This family covers the small diameters of racing wheelchairs. The S3 20" Lite, under 100 g, equips the front steering wheel. The S3 Road 26 mm versions, from 20 to 26 inches, equip drive wheels, handbikes and racing scooters.
Fitting
Like the MS3, they fit without glue on rims of specific dimensions: the tubular sits against the rim walls, does not slip and cushions side impacts. That allows them to be changed at a competition venue with no drying time.
The construction
SPC Silica and carbon-black rubber, standard puncture protection, rubber puncture strip, guaranteed maximum weight. Pressure up to 15 bar.
