Ha! That truly is a unique experience..

There WAS a local builder named, Chris Wittman made frames under the "Slim" label (don't ask)

He called me up one day asking to come to my home work shop (Cirque folks know it well) and have me assist him with my alignment table on an Columbus EL-OS frame that he"had built a little off." Oh yeah, it was a little off alright!

Anyway, I let him do the brute force bit after I had clamped it in and realized how far off it really was... He grunted and heaved and jumped up using his whole body to try to bend it... Then out of the blue, it went POW! Totally twisted into a wrinkle potato chip! Awesome! But we both were amazed how much oomph he had to use.. Steel is real, baby!

Some steel frames, anyway. I wouldn't try that with a 753 frame!

We had more than a couple crashed 753 frames returned to us at Trek; we'd just build a new frame as a replacement. Reynolds did not recommend cold-setting 753, so we decided to see what would happen using these damaged frames as crash-test dummies. Executive summary: Reynolds wasn't kidding. Rather than taking a cold set, 753 resists completely until a critical threshold, then fails completely.
