Please help to identify a value and quality of a frameset =)
 

Hi folks! One guy is selling a road frameset, labelled "G.S.r.biri". I've googled around this brand and found just nothing, except few bikes in Poland. Is this frame worth USD 100?

I'd say it could be worth that. Maybe more. Of course, as long as there is no damage other than typical scratches. It's neat.

what kind of tubing does it has ? I think it would be wise to ask the owner first about it .

Looks like a quality frame to me , and where many italian quality brands in the past that are unknown to the wide public . But still , you better find about it as much as you can .

I would guess say it is worth a $100 if it has no significant issues. The lug work and construction look to be of better quailty and very interesting neat. Any chance of getting a close up of the tubing sticker and seat cluster. Also it might just be the pics but it looks like the BB may be dinged in at the bootom on one side I would check this closesly in person before buying.
