Gppd you found a buyer and got a nice sale.
I have owned a few Klein bikes and they are very nice rides, light and stiff.
The steels and carbons are preferred by the majority of riders.
In the 2002+ models, Klein replaced 6061 aluminium alloy with a new alloy called ZR 9000, that used zirconium in place of chromium; the new alloy had not been assigned an industry number and it was named after the unused 9000 series.
I have a 2006 Dedacci Aluminum Italian racer that rides wonderful on par with my steels and TI bikes.
Love the color of this offering.
