Loudest hub I've personally had the pleasure of hearing. So rest assured that you won't have to announce your presence on the trail. Others will hear you coming from a long way off. This wheel is also super easy to set up tubeless, and really lightweight for not being carbon.
I've cycled through a couple roof mount yakima/thule bike racks and this is by far the most secure. The mechanism to lock the front wheel into place is well made and very intuitive. In addition the locking cable is sleek and easily stored, making it difficult for would be thieves to steal your bike.
