Hamish: I had a Catalyst, but it developed a crack in the right seatstay and I had it replaced under warranty (have to love a lifetime warranty!)
staveb: I took a bus north, to a town called Akureyri, and basically rode straight south from there. Right across the highlands and back to Reykjavik. I was originally planing to spend two weeks up there, riding North from Reykjavik and then basically taking whatever paths I could find up there in the highlands. Unfortunately I slipped and banged my ankle on my second day - got a swelling the size of a tennis ball - so I had to cut the trip a bit short. I stayed home for a few days, recovering, and then set out again. One thing I discovered on that trip is that butterfly bars don't give you enough leverage to negotiate really rough ground, especially downhill when you have to keep your hands on the brakes.
