Sometime in the future I was going to change the rims on the Thorn to the rigida ones. The ones where they fire carbide at seven times the speed of sound into the rims. The rims on my Santos have them and they show no sign of wear, even though the bike had done 20,000 km before I bought it. I say was, because when I looked at them today I discovered that was exactly the rims that are on the bike. You would think he would have mentioned it in the listing?!!
