As an entry level product into the HED family, these spin up quickly and roll smooth out of the box.
Keep in mind , you will need a longer valve of you are staying clincher.
This is my first carbon wheel. Upigraded from the stock alloy on my Trek Domane. The price was excellent with the sale , and the performance so far has been a very noticeable difference in the ride. Climbing, even just cruising on flats, seems much easier and faster. Highly recommend.
