It took me a couple months to break my butt in on a Spesh Avatar Expert. That was probably on top of months on a Fizik Aliante VS on another bike.

Both seats were good for 5 miles, after that I had to fidget and stop often.

After a few months, both seats are OK for up to 36 miles, my longest ride so far. I still lift off the seats a bit and stop for a snack now and then, but consider them good saddles.

My thinking now would be, on a unseasoned butt the seat should be good for 5 comfortable miles.

I tried a Spesh Romin. Only got a couple comfortable miles out of it, returned it and got the Avatar.
