This is the brand new Profile Design HC Bottle. The HC stands for 'Horizontal Cage.' After years of bucking the BTA trend, Profile Design has seen the light. With the HC bottle, they've clearly embraced the notion that consumers want these types of products, and they're satisfying that demand with a really smart offering that is going to wow a lot of people.
Profile Design sells the bottle complete with a compatible cage, a mounting system, and an integrated computer mount. You can figure out your own mounting setup if desired, but the stock one will work well.
