2011 DK Opsis

For my tragic/comic attempts at learning some flatland . . .

6/17/14 Updates

I've gradually made some changes/upgrades over the last year or so.  I added a 53mm DK Alpha Stem, 28T DK Chaka sprocket, new Odyssey Hazard Lite Rims, and Demolition Momentum tires.  

I really like this bike a lot and am disappointed to learn that DK will no longer be offering the Opsis in their lineup.  I've made several upgrades, which sadly have not helped make the flatland learning process any easier.  I replaced the crappy plastic seat with an Odyssey Aiken model, added 9" S&M Intrikat bars, and replaced the crapola Tektro brakes with an Odyssey Evo II in the front, and Dia-tech Hombre in the rear, with Odyssey Ghost Pads.  Since I'm 6'3" and the bike felt short for me, I added a 43mm DK Alpha Stem, versus the 37mm stock one that was on it.  For tires I went with Odyssey Frequency Gs.  I also was fortunate to win some parts from last year during their holiday giveaway and used the Primo pedals and seatpost I got from them.
