Description
Hard to find Shimano Deore XT BioPace inner chainring from the late 80s/early 90s when XT was the top of the range off road group. The FC-M730 chainset was used for a long time and these high polish silver rings were around in the second and third iterations of the groups: M732 and M735. BioPace was designed to offer the rider a more effective pedal stroke, it was reasonably short lived but came back with a vengeance in the mid 2000s when the bike industry had run out of new things to invent. The oval chainrings supposedly put more power into the top part of the pedal stroke thus making you faster and/or making it easier.
