What is 41-Thermal?
41-Thermal is the 4130 chromoly manufacturing process that starts at the design stage, carries on throughout manufacturing, and is only completed when we reach the finishing steps. There are an endless amount of variables to fine tune, and every action along the way counts and matters.
We introduced 41-Thermal in 1999, and the process continues to evolve and change along with the products which proudly carry this famously trademarked name. Other companies have attempted to write the process off as a “gimmick” or they’ll say, “it’s just heat-treating.”
The truth however is that nothing has revolutionized the manufacturing of chromoly BMX forks, bars, cranks and frames like 41-Thermal has.
We pioneered it, developed it and continue to perfect it, never at the mercy of feebly asking manufacturers to do “whatever that other company is doing.” Our lab and ride testing is methodical – constantly striving to make the process better through continuous experimentation and true engineering.
Lab tested. Team Proven.
Our product testing goes above and beyond the industry standard.
- Much higher load than industry standard EN tests
- Load is applied in the correct direction
- Proper mounting rig to replicate real world use
- Test doesn’t stop until the product fails
Unmatched and Legendary Lifetime Warranty
41-Thermal products are backed by years of research and development. Most brands limit their lifetime warranty to defects alone, which is essentially just a promise that the product was made properly. The 41-Thermal Lifetime Warranty goes above and beyond.
*Normal riding conditions defined as “Using the bicycle in a controlled fashion that is within your own capabilities.” External forces such as cars, tornadoes, sledgehammers, etc. are not covered because that would be absurd. View full details and product registration.
