I've never seen a Retrospec in person, but given that their website doesn't even bother telling you WHAT type of steel they're using and the fact that they look like Pure Fixes or Big Shots sister company, I'd say yes they're junk. It's a fashion statement, not a bike.

Windsor on the other hand has some fans. It's a bikesdirect brand.

Depending on your budget, most people will recommend the Kilo TT.
