While the Sequoia bb is higher than the Diverge bb, the Sequoia does not have a high bb in general. It's lower than most mtb bb's and many cx and road bike bb's. The Diverge has a much lower bb than usual so it just looks like the Sequoia has a "high" bb in comparison. I've found that the Sequoia's bb drop is the best for my mixed 50/50 on/off road riding. That bb drop is very stable in both conditions. No, I do not have a Sequoia or Diverge but have a Roger that has similar geo to the Sequoia.
Thanks for the feedback. Would you suspect the Diverge bb would be too low for off road riding? Off road / gravel etc is all pretty new territory for me.
