wrooom- I have sugino 75 crank and ring and love them both. The crank is nice and stiff. I don't race at a track, but I ride pretty hard sometimes and even do "sprints" on flat straightaways.

The ring is nice and round. Almost perfectly. The chain maintains an even level of tightness no matter what position the pedals are in.

The finish on both the ring and the crank is very smooth looking. No flaws

What else do you want from a crank? How about you tell us exactly what is wrong with Sugino 75 stuff instead of just spreading your magic hate dust all over it...
