I’m on the fence between the Aeroroad CF SLX 8.0 disc Di2 and the same version of the ultimate. They are about the same price. I’m a tall rider between XL and 2XL. I’ve been leaning to getting the Ultimate but I went to a Rapha rep and he said he enjoyed the more upright position of the Aero vs with the Ultimate he said it felt like you are more hunched over. I was expecting the opposite but thought I would check here. Thanks!
