I've tensioned my B67 8 or 9 times already. Diane at Wallbike said that was the only way to get it to stop creaking and groaning and snapping and twanging. My B67 might be the 5% that just won't stop being noisy.
Pretty sure that after the tri I'll be sending it back. Most comfortable saddle i've EVER used, but I can't stand the noise and feeling like it's gonna fall apart under me.
I'll talk to Bill and Diane, but I think I'll skip the springs which allow the frame to torque and replace it with a B72. I don't want another noisy beastie.
I'm sticking with Brooks.
