I have a Sugino XD 600 and LX crankset. I was just thinking I never used my lowest gear on my crankset. And this crankset is getting worn down. I was thinking of a two ring crankset, and a 8-Speed Road Cassette 12-26. My commute is a very flat run, and thought I could get smaller grouping of gearing with a 8-Speed Road Cassette 12-26.
