Some industrial designer *genius* working for Arkel has finally figured out a simple and elegant way to install a rack on a carbon seat post without putting *any* stress on the carbon fiber! After having a rack on my carbon seat post for 3 years and always wondering in the back of my mind if my post was under weight stress, I now have a more stable rack that holds more weight if needed, without being attached to the post at all (just resting on it). What a simple and brilliant idea to attach the rack to the seat *rails* and just rest the rack against the post! I would give this product 10 stars if I could. The rack is actually very easy to install (you only need a 5mm hex key) but it took me a few more minutes than necessary because the instructions could have been worded a little more clearly and the illustrations were not as helpful as the could have been.
You just need to loosely attach the clamp to the seat rails, loosen the hex nut on the rack to pull it straight and parallel to the ground, attach the velcro seat post 'clamp' and then tighten the hex nut and the quick release seat rail clamp. It should only take about 5 minutes! Genius.
