Merlin MTS325 frames, which include the Extralight, XLM, Road, Mountain and Aerial are built with Merlin MTS325 seamless titanium tubing throughout. The MTS325 standard is based on a set of four aerospace specifications, but with stricter tolerances for finish quality, which affects fatigue endurance, and for straightness, which is critical for final frame alignment. Certification is a fail-safe tracking system of quality control and continuous testing that follows the tubing as it is being manufactured. The MTS325 certification standards call for intermediate ultrasonic testing, which is usually omitted for non-aerospace tubing, and for more rigorous final ultrasonic testing and eddy current testing. These tests measure finish quality and dimensional accuracy, and if the tubing fails any test or inspection, we reject it.
Certification is our guarantee of the highest possible tubing quality and performance.
We also offer custom Road and Extralight frames through our Made to Measure program. Touring, triathlon and cyclocross frame styles are available, along with custom variations of our road racing frames. For complete details, please ask for a copy of our Made to Measure brochure.
