Dose anybody have experience with the SDG i beam system? I am looking for a way to get more than 25mm of setback on a seat post. from the web this system appears to provide the setback I'm looking for but at 300lbs not sure if I am too heavy for the i beam post and saddle. any help would be appreciated.
