Interesting that there's a "T" in the serial number. T typically indicates an Attitude serial number from the pre-Trek days. Post-Trek, the Attitudes had, I believe, an L in the serial number because Klein started tubes from the Pulse.
I think and this is a guess that when trek bought Klein they bought left over tube sets and if i guess right i would think that when the bb tube was made in say 95/96 it was then left in stock and when trek bought Klein they just used all there old stock first then stamped it when it was connected to a bike, so the t i would presume means attitude due to the fact that the part is from an old attitude.
only a guess and im sure i put that all wrong
