Dura Ace seems to be too expensive, so I will probably keep what I have right now, the 7700 group. I may be changing the cassette from 7700 Dura Ace to a 6500 Ultegra, 9-speed.

I will also be changing the wheels, since the rim wear is too big on the existing ones.

So, incoming changes:

• Shimano WH-R501-30 Wheelset – Clincher – white
• Continental Grand Prix 4000 S II Folding Tire + Race 28 Tube – 25-622 – black, Valve length : S60 – 60mm
• VeloPlugs Rim Plugs
• Shimano Ultegra CS-6500 Cassette 9-speed

And hope for the best, especially time to ride my bike…
