A Polish handcrafted frame - also goes under the name "Ten-Four" (10-4 as stamped on right rear dropout). Built it up to withstand a commute of 25km. daily. In itself the bike was pretty decent all-round. Boring performance, but it effectively got me from a to b.

is it just super flat where you live? i feel like this is a huge gear to push around town

Denmark is the most flat country you'll find! Our tallest "mountain" rises 170m from sea level... That said, yes it's ridiculous. I only rode this ratio for a week or so, found it uncomfortable that my legs never got to spinning before going +40mph downhill. Normally I'd say the heaviest I can push while still feeling good is 50/15.

Looks like a mean machine (next to what i assume is a very sweet & fluffy one), nice!

Thanks man! I can assure you it is - mean - the other one is indeed sweet and fluffy :)

I think they are made by Mielec

In fact they are made on Mielec's factory, yes! The frame is designed by an other guy, though, who contacted Mielec to get them to help him build his bikes. It ultimately led to Mielec overtaking the production of these frames - while the original designer has been forgotten. Thanks for the input! :)

I really like this bike! Did you ever have any issues with your tires seeding properly on your Miche wheelset?

Thanks a lot - your bikes are sweet! No they were pretty straight-forward as I remember them... They're mass produced so flaws shouldn't happen - have you tried different tires?

Thanks! Thanks for the response. Hmm thats weird. I have tried other tires, and they just do not want to sit in the rim properly. Always one edge would pulled toward the center of the rum, like the rim was slighly too big for the tire. I got a blister on my hand just from removing the tire :(. Thanks anyways!
