HollowGram R-S 50 wheelset from Cannondale. Super nice carbon wheelset built to modern standards (optimized for 30mm tires) and uses DT Swiss's reliable 350 hub as internals, which also makes them super easy to service. According to Strava I've ridden under 10k km on them, so there's around +20k km before they need servicing. Currently equipped with a 54t ratchet, but i can downgrade to 18 (the original) for a 50 euro discount. 54t however makes the engagement faster and the sound better.

There are naturally cosmetic blemish and sign of use, but only cosmetic.
