I originally built my commuter up with cr720's (same thing) but I couldn't get the front brake adjusted to work right and I also had issues with them centering correctly so I eventually swapped in tektro rx-5's http://www.amazon.com/Tektro-Mini-Al.../dp/B000C17NPC. The mini-v's work much much better with my tiagra 9 speed levers. Adjustment is super easy and even though the lever has some play to it they have much more braking power. I am running coolstop salmon pads

I don't know if they will clear your tire+fender I am running 700c 35mm tires and it looks like I might have barely enough room for fenders

your LHT has barcons right? why not swap normal v's in and change the levers while you are at it?
