Columbus SLX tubing question

[OutlawGeek]

I got one nice Peugeot frame - '89-'90 Dolomites like on the second picture.
Sticker on the down tube says that this one made from Columbus SLX tubes.
And there is no helical ribbing in the seat tube.
Is it truly SLX frame? Or tube rifling were made in various parts of tube?

SLX rifling on the seat tube is only at the bottom joint at the BB - have you checked there?

I think I see the beginnings of a rifle!

I had this very frame and yes, despite it being a Peugeot and not the best quality frame in the world it was deffo an SLX if the ribs on the lower part of the seat tube are the benchmark that is.

Interestingly mine was Campagnolo Athena not 105.

Theres a reason theres no rifling at the top of the seat tube
No seriously it will be a short rifling on the lower seat tube as well as each end of the main tubes.
