In USD it was about $270 plus $80 trans-Atlantic air freight via Royal Mail Global Priority.
Ignore the bit about it accepting only 23mm tyres. Mine fits Continental GrandPrix 4-Seasons in 25mm under the SKS P-35 Chromoplastics Longboard mudguards with no problem. I prefer to run 28mm, and for that, I had to cut the rear mudguard where it passed through the rear brake and mount it using
Reacharound Fender Brackets. Look at the rear brake bridge to see how it works. The front fits the 28mm just fine with room to spare, box stock.
The bike is an absolute delight. I recommend it unreservedly.
BTW, the bike it replaced was my Trek 1000, the previous iteration of your Trek 1.2. It is a far better bike by every measure.
