The Cogent shock is still available for $300 plus shipping, but there is a party ahead of you who have asked for it. He has been waiting for me to get back from a bike trip to Canada. I have to allow him first refusal.... and then you are welcome to it if he decides against. Fred
I think I paid $600 when new. It is in very good condition never been off-road.
Think you would be fine at your weight, especially if you have Tusk panniers and a top case etc. It is also adjustable. It really transformed the NC handling and comfort. Message me with your zip code and I'll get you a FEDEX ground discounted shipping rate estimate.
