Few brands have been more intimately connected to the last 100 years of cycling than Silca. The Italian-born brand's legacy of legendary quality has seen company's pumps being passed down through generations of professional mechanics and cycling enthusiasts - riders who value the experience of bike maintenance and understand its performance value. Now based in the US, Silca's heirloom quality pumps have been joined by a growing selection of thoughtfully designed and stylish accessories.
Why Latex? Compared to standard bicycle inner tubes which are made of butyl rubber, Latex is significantly more elastic (10x elongation compared to 2-3x), but more importantly, Latex Rubber has significantly lower coefficient of damping which means that when latex rubber is stretched or flexed, it returns to shape faster and with fewer energy losses.
What does this mean for an inner tube? Latex inner tubes are generally 2-5 Watts (per tire) more efficient at 30mph than tubes made of other materials, are harder to pinch-flat, and offer superior suppleness and road feel, especially when combined with supple, low rolling resistance tires.This tube has been sized to fit tires measuring 24-30mm, which will equate to 23-28mm tires used on modern wider rims. Valve stem length is 42mm and will work in all modern disc wheels.
Optimized for tires measuring: 24-30MM (Tires marked 22-28mm when used on wide rims, or tires marked 24-30mm used on older narrow rims)
42mm valve stem, works in all modern disc wheels
