My Designer '84 is a mid 80s with full Campagnolo Chorus 8 speed update. It has been in my stable of daily riders for many years, usually ~8 bikes out of too many in the collection. Right now the daily rider company are two built for me customs, a Tommasini Tecno and Prestige, a Colnago Master, a Vitus 979 and a Pinarello Montello. I highly value handling in crisis situations (blown front tire, oil slick on a curve, etc. ) and the Master and CIOCC have proven themselves. It's the original brilliant red and I may hear more "Nice old bike" as the latest carbon rocket passes me than any of the others and certainly it draws conversation from folks who don't know the mark. It's not the lightest or fastest but not far off and one of the ones I take when I am trying to keep up with the kids. I have always found SLX a nice ride and while I would not choose it for a 40+ mile ride its classic racing geometry is not what I would call "twitchy".
