Bike Mielec

The forks are Columbus Tusk Air as mentioned. The Columbus logos are taped over.

Confirm that. they goes for 100€ shipped, here. Rake 45mm, 375 axle-to-crown, more or less 600 grams.

Nice Mielec.
Not that kean on the cockpit - but you got that sorted. It will look good with the new black rims as well.

What size and geo is it?
My 59 cm weighs 1.702 kg

it's a 54cm, so i think it does make sense.
74° head angle, 75.5° seat angle, 384mm chainstay, 52 mm drop and -3° top tube slope the geos =)
What do you mean for "kean"? i did not understand. But thank you for your feedback. =)
