Great saddle. Very comfortable
This is the third Zeta saddle I have ordered. I am putting them on all my bikes. These saddles have alleviated sit bone pain and eliminated skin chaffing.

Zeta on touring bicycle
The ZETA optima resolved sitting issues. Comfortable! Used on a two day shakedown overnighter ride and then a 5 day bikepacking tour in Kentucky. All good for longer trips.

the solution to my soreness problem
The optima is the 6th saddle I've tried in my search for comfort on my bike and it feels like it might be the one. Its the right width for me and the padding is softer than others i've tried while still providing support. Yes, it was pre-owned but it looks brand new.
