Description You might be asking yourself, "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. The Silca Latex 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.

Great for wider tires
Latex tubes, paired with high quality tires, provide great road feel and modestly lower rolling resistance than butyl tubes. Silca's are designed for wider tires (think 25mm ), and work nicely with wider contemporary clincher rims, which can add 2-3mm effective width to your tires. The valve stem-42mm-is perfect for most low profile rims, and not uneccessarily long given that deeper rims will need extenders anyway...These tubes aren't cheap, but last long and are worth the extra bucks to optimize your ride.

PRs Improved
Switched to GP 4000S II and these latex tubes, my times have definitely improved slightly - nothing like a wheel upgrade but I'll take any improvement I can get.

Faster
Research says 2-5 watts per wheel. If youre a TT racer, thats huge. Theyre not cheap, but winning sometimes takes a little extra.

There is a difference, on can feel it...and seems to measure on Strava
The Latex tubes were less fussy to install than I feared they would be. now with several hundred miles on them they feel inspired. The ride is more comfortable than t was with the butyl tubes, I adjust the air pressure before each ride....a very good purchase.

Free Speed! For a modest price.
The studies say 2-5 watts per wheel, so I guess I gotta have em for my TT bike! Plus, these have a durable stem with the perfect length to fit my disk wheel.
