Argon 18 Radon 2017 fork question

[DavidMtl]

I just bought a 2017 Argon 18 Radon frame NOS without the fork. I'm wondering what was the original fork steerer tube size (1 1/8 straight?).

Someone have this info?

Thanks!

If you have the frame, you should be able to tell what sized fork will fit by measuring the size of the bearings the frame takes.

1 1/8 bearings are generally 41mm wide, 1 1/2 bearings are generally 51-52mm, and 1 1/4 bearings are a little more variable, but commonly 44-47mm.

The heat tube is 41mm straight so I assume the fork is 1 1/8 sraight. Thanks a lot!
