I checked the serial list
Hi Mcada, thanks for checking! Yes, just the seat cluster brazing.I checked the serial list
http://ritchey.vintagebicycledatabase.com/listing.phpUsually there is a letter, but some have these short numbers not following the concept
I can't appoint a model and I'm not sure this is a TR, mainly because of the cable routing and brake bosses
Another point is, it looks as if it's half brazed. (Only the back)? Correct? Not sure which model this had.
Did those even ever exist? Where does that info come from? Was TR doing work for KHS or did someone there bought a couple of Ritchey bikes for the team?Is it one of those KHS Montana Teams that were built by Ritchey? Before they went to True Temper?
