Yup, I read too fast and missed the Sachs part. however, I stand by the spring tension issue. Around '96, Shimano switched most of their rear derailleur parallelogram springs from the stronger torsion springs to the lighter tension linear coil springs. This adversely affected shifting in the smaller cog range and gave Gripshift a bad reputation for a time. A lot of aftermarket parts were sold to counter this, from higher tension springs to Bass Worms - remember those?
