I've just got a new Felt B2 Pro that comes with the same wheelset but clincher.
Therefore, I am selling my 2008 tubular Zipp 606 wheelset - 404 front and 808 rear. The set comes with Zipp titanium skewers, Shimano Dura-ace 11-23 cassette, Continental Competition tires.
This set has been used only four times on 70.3 races.
Price: $2,000 for the whole package.
If interested, please email me at firstname.lastname@example.org and I can send pictures or we can arrange a visit to inspect the wheels.
