I recently purchased a second hand Giant road bicycle, a TCR Comp.. Dura ace groupset, shimano 105 Brakes, and Ultegra Cranks. I have an emotional attachment to this bike as was the first bike i managed to push to over 75kph.
Here is a picture i found on-line of one very similar, I will upload some actual pictures of my bike sometime this week.
The only visible difference between this bike and mine is the wheels, i have ALX600’s on mine. I’v done about 400km so far on these rims, and so far they are handling very well. Did a bit of research and found they are a bit pricey, but very durable. Between $600 and $900 for the wheelset. Do a bit of looking before settling on a supplier as you may find cheaper.
