Description
Silica has now partnered with Vittoria to create the world's most advanced inner tube that reduces rolling resistance and rim-driven punctures, along with the best ride feel for modern clincher tire setups.
Why Latex? Compared to standard bicycle inner tubes made of butyl rubber, latex is considerably more elastiC The damping coefficient of latex rubber is considerably lower, and after stretching latex rubber returns to its normal shape faster and with less energy loss. What this means is that the use of a latex inner tube will generally increase efficiency by an average of 2 to 5 watts (per tire) over a 48 km cruise compared to a tube made of other materials. They are also much less likely to puncture the rim and provide superior grip and feel when used with flexible, low-rolling tires.
The tube is designed to fit 24-30mm tires, which is equivalent to the 23-28mm tires used on today's increasingly wider rim widths. The valve stem length is 42mm and can be used on all modern disc wheels.
In a 2014 interview with Slowtwitch.com, developer and owner Josh said the latex inner tube is the easiest and greatest benefit upgrade custom cyclists can makE Until recently, latex inner tubes were primarily limited to use with tubular tires. Latex tubing is closely associated with both the superior puncture resistance and ride quality of tubular tires.
And Josh put this in simple numbers.
Silica latex inner tube upgrade (2 wheels): 4-10 watts, $30
Full wheelset ceramic bearing upgrade (6 cartridges): 0.8-1 watt savings, $400-$1000.
Ceramic bearing derailleur pulleys: 1-3 watts, $200-400.
Latest aero road helmet: 4-8 watts, $300.
SPEC
- Ideal for tire measurements: 24-30MM (22-28mm tires when used on wide rims, 24-30mm tires when used on narrower rims)
- Premium latex, 42mm valve stem
- Compatible with all modern disc wheels
- Removable Presta valve core
- 85 grams
When using latex inner tubes, it is strongly recommended to use tubeless rim tape. Tubeless rim tape makes installation easier for any tire and reduces rim-striking punctures.
