Though I recommend The V-GT and VX versions I am more reserved about the Cyclone GT as the cage tensioning springs were prone to failure. This was a common problem and I do not know if this was due to lightness of construction or what. My standard recommendation was afore mentioned Derailleurs (so see I was a retro guy even in the 70s!!) I do not remember when the major redesign was done (Superbe Pro) and thats probably Off Topic anyway
