Customer Reviews
I have been riding Crestones for 6 or 7 years now and have used them for literally everything. I’ve used them for XC racing, ripping up a bike park, to bombing down ski runs. It’s super lightweight (mine is 23lbs at the moment), fast and very fun! If I could have one bike forever it would be a Crestone!
Nonostante la richiesta di spiegazioni la bici non ancora arriva e non capisco perché.
