Just got a Cyclone Mk2 groupset with a Symetric shifter (that I can't use without an adaptor) and I will be putting new d's on my sister's Centurion to upgrade the existing Suntour 7 group.

Suntour Cyclone 1 and 2 are very nice components... I am looking to replace the 600 Arabesque on my Raleigh with an early Cyclone group as it nearly as ornate and will work much better.
