Hello. I have a rear triangle alignment problem on my Merlin (identified using the old string method) and confirmed to NOT be correct alignment by the frame's designer (Tom Kellogg). Merlin says that the frame can be sent back to the factory where they will cold-set it back into alignment like a steel frame. Having cold-set steel frames in the past, I am familiar with the technique. But I wonder if there are any special tips or techniques that should be used when working with ti? Thanks in advance for any info you can provide.

The force is less but the overbend necessary to get a set is a lot greater. This sort of thing is best left to someone who has practiced it.

you don't want or need to know, just send it back to merlin.

Tom's right - it DOES take a lot of deflection on a ti frame to get it to "take a set". Merlins have beefy stays similar to those on a Habanero, and would no doubt take a similar amount of force to realign.
I wouldn't be too paranoid about cold-setting it, but would sincerely recommend going slowly and carefully. Brace the frame, apply the force and re-check. Repeat until straight. In the end, don't be surprised if you end up literally standing on the frame to get it where you want it (which seems like a lot for a 3-ish pound frame, but they're pretty tough).
