"Looked into that option - but I don't care for the higher position of the seat, and less travel fore and aft."
Raque,
I put in the Tone's seat extenders and love them. I didn't notice any appreciable height difference even though I know it's there. Maybe I'm just less sensitive than others to it though because I've heard others with that complaint. I think the extenders only put the seat about 1/2 inch higher.
The seat extenders won't affect seat travel fore and aft. The extenders just move the whole mechanism several inches forward so the travel remains the same. The only thing you lose is how far back you can adjust the seat and that hasn't been an issue for us.
