just pulled off my drive side crank to set my bike up single speed for the winter .Curiousity got the best of me when I had the arm off ,so I weighed the gravity brand crank arm and noticed it was a 170 mm arm .Its a 18inch frame can anyone else confirm this.Since I normally run 175 or 180 I haven't really noticed it . I guess I'll find out if I like 170mm for ss this evening.Anyway just wondering because I couldn't find where it said 170mm on their spec. Sheet
