Klein Quantum vs Aura

[airtrainer]

Hi all !
New to the forum, I'm currently looking for a Klein... I knew the Quantum from when I was riding but just discovered a later model, the Aura. Any thoughts on these two ? From what I see the pre-Trek Quantum is more desirable, but would the Aura be a bad choice ?
Thanks for any imput !

Hi All,

Didn't want to start another Kl**n Quantum topic, so apologies for resurrecting this thread with a question.

A Quantum from 1994 - would that be aluminium or steel frameset? And if steel, then what steel?

Thank you.
