Currently using a Toupe 143m, after 15 months it has given way in the middle. I turned to this saddle seeking relief from numbness, and to this extent it has been ok, but not great. I'm liking the design of the mantra - the large cutout and the sweeping sides look ideal for my needs; the aforementioned numbness and also saddle sores. Although, to my own discredit, I've recently overhauled the saddle position and now find the toupe much better with respect to these!! Still, I need a replacement due to sagging. Any thoughts from users of the Mantra, it'd be great to hear from anyone with >= 12-months use? Comparisons to the Toupe?
Much appreciated
