I've got a 52cm Cross Check.
4 years old.
I changed the tires to Vittoria Randonneurs (32mm). Switched the drop bars for moustaches, and gave her a 120 deg rise dimension stem. Added a third -granny- chainring. Brooks B67 saddle. Rack and fenders.
Eventually I bought her a new fork so I could get a longer steerer as I was having some trouble in traffic. Couldn't quite see over cars.
I love this bike in every way. I've ridden long distances, short distances, commutes, drafting a better rider, toodling along on dirt. She's done Costco runs with two panniers and can pull a trailer.
If I only had one bike, this would be it.
Right now I'm yearning for a Soma Buena Vista because I want a mixte and I'm a fickle woman. But really, I have nothing bad to say about my Cross Check.
