Eclat Torch 15 Seat PostEclat have really hit the nail on the head with this one! The Eclat Torch 15 seat post has a 15mm offset, knocking your seat back just that little further. This allows more room in between your stem and seat for your legs to move around in. I love this idea and thats why for the last few years Ive used the Eclat Torch 15 post. Epic.
