Yes, they offer an A29 compound which they call "hard" and an A30 compound which they call "medium". But as I look at it, you may not have had a choice depending on the size you purchased. The 275 and 295 sizes are only available in the A29 / Hard compound and they probably matched that up with the same for the front if you're running one of those sizes in the rear. I am looking at a 225 front, 245 rear and have a choice.
Glad you like them, wish they were cheaper...
