They felt solid, and ran very smoothy (love the sound of the hubs – ceramic was worth it just for that)
No creaking when climbing steep hills out of the saddle and under load (650 watts according to the power meter).
Felt light and easy to accelerate.
Significant improvement on the Shimano dura ace c60’s
Paired with the GP5000 28c’s , the wider rim seem to make it feel like there was more rubber on the road – builds confidence on the grip.
Match pads were OK on the graphite rim.. the previous AL breaking surface / Shimano pads had a touch more grip and certainty, but the Koolstop pads were smooth and felt reliable
