For many years I only used Shimano bottom brackets. I recently picked myself up a cool pair of used FSA carbon cranks and bb on ebay. Installed the cranks/bb and noticed a tiny amount of play when I grasped both crankarm ends. The bb was very smooth and rode out fine, but I attributed the amount of play to wear in the bearings. I went ahead and bought FSA’s new top of the line Isis bb, the megaquad something or other. To my surprise when everthing was installed and tightened there was a similar amount of play when I grabbed the crankarms and wiggled them. The amount of wiggle is very small, but I never had that issue with my other bikes equipped with shimano bbs. I certainly don’t notice it while riding, but my question is whether this is common with Isis bbs?
Thanks
