6’4” 275# isn’t gentle on seats and posts.

Time for a new seat! what to get? I like Brooks and have 2 more leather ones in other bikes. But are there seats with stronger seat rails? Brooks should be steel but I don’t know what grade and strength.

I use the Kinekt suspension seatpost also. I bought a Spongy Wonder noseless saddle years ago and the manufacture recommended replacing the seat clamp bolts on seatposts with Grade 8 bolts. His saddle design if slid back far enough would put a heck of a twisting load on the seat clamp. Ever since I have been careful to try to get saddles and handlebar setups that centered the seatpost load in a more vertical up and down direction. I have used the Spongy Wonder for years pushed way forward which centers the load over the clamp and have not had any clamp bolt issues. Just another thing to think about at my weight range (260lbs). I love the Kinekt seatpost. Best suspension seatpost I've owned and used by far.
