I struggled between 3 and 4 in fairness
- Familiarity: I've used it several times
- Fit: True to size
Let's call this a 3.5... this is a racing saddle. RACING is the point to take away from this. I don't recommend this for seated endurance rides at any length. It's nice and light, feels great for 45 minutes, but anything longer than that it's unbearable. Lots of hotspots and sit bone pressure, which is surprising because for the first 30 minutes it feels like a pillow.
I would recommend this to anyone who is putting it on a race bike where they intend to stand for lots of efforts. Do NOT put this on the training bike you use for doing 3.5 hours at endurance pace or anything like that. Additionally, there aren't a million ways to sit on this one, it gives you a solid powerful position and you're pretty much stuck there.
