I've used Albins gears for years, so has Tony Flood. I'd rate them as good as PPG they just are not marketed as well as PPG outside of motorsport. I have broken a 5th and a second gear in 4 seasons of hard core rallying using synchro helical group 'N' gears. I currently have a straight cut Albins dog drive (all 5 gears) but in a road car I wouldn't go past a 6MT. Less stuffing around than a built 5 speed in my opinion.
