I just recently bought a Klein Pulse Pro. From my searching, I cannot find any information on how to decode this serial number. It seems to be different from most of the other numbers I've seen. Help please! Im figuring it's a 97-98 with a 20" frame. I've emailed trek and they said the numbers are not in their system.

Hello hillbillymachi -

That serial number has the same format as used by Trek. I have not sorted out all of the number, but this is what I think: The N means 1997 (or less likely 1996 or 1998. The 025 is the 25th frame of the year. You are right about the 20. The KB means Klein Bikes. When I get more of that format sorted out, I will post it on my site.

Cheers,
