Splines? Was this a Power Spline crank? If so that's some of the issue. For the number of them in service and for their claims to be stronger (splines Vs tapered square) they seem to have more loosening up problems. Maybe it's because they come on some bikes that are made to appeal to the up and coming but not yet savvy rider but don't cost enough to have a shop do a better then usual assembly job. I don't know why I just see more issues with them statisticly then other designs.
Power Splines are a Truvativ product and are not Octalink or ISIS. We don't see the same problems with them as we do with Power Splines. Andy.
