I agree with Garth about the poor gear progressions on the 13-34 Jim. The Shimano HG-50-K 13-134 is 13-15-17-20-24-29-34 which IMHO is much better, it avoids the 15-18 problem and has 2-3-4-5-5 spacing above 15 vs the Jim's 3-3-3-4-6 spacing. I used the HG-50-K on my 88 Voyageur and gives very good spacing. IRD also sold the same copy of a HG-50-K for about $30 2 years ago. I do not see it in the IRD store now. Maybe they changed suppliers.
The 13-42 is also poor do to the 13-16 jump leaving NO 2 step drop for the high gears. My 1975 Shimano 14-32 5 speed had a 14-17 jump and was always frustrating on level terrain finding a good high cog. The 13-15 solves that. In all, why does anyone want to go from 9 speed to 7 speed??? I can see them saying here is a supply of 7 speed for folks with 126 OLD rears, but if you have a 130 OLD rear just use the 9 speeds out there. They have better progression. I think RBW is pitching folks a lemon with these as saying convert from 9 to 7 speeds.
