I've been riding the same seatpost that came stock on my Raleigh R700 seven years ago. It has no identifying features, no logos, no stickers, no imprints, nothing to differentiate it from any other seatpost in the world. But, it faithfully did it's job. I never really questioned whether or not I could improve on it or not. I don't know how much it weighs, it's a standard shape and has a standard seatrail clamp. For all intensive purposes, it is generic...
When I was at the North American Handmade Bicycle Show several months ago, I came across a bicycle manufacturer named Kent Eriksen. Their bikes were nicely handcrafted machines but, the one thing that really struck my eye (oddly) was their seatposts. Their Sweetpost seatpost appeared simple, clean, and almost virtuous. What do I mean by that? I am a big fan of simple effective design. If elements of a component can be eliminated without reducing the functionality of the whole, then I feel those elements were superfluous. In my opinion, reducing unnecessary elements, while retaining durable, effective structure and function elevates a component to the next level.
With this seatpost, Kent Eriksen has done just that. The head of the post consists of nothing more than a titanium cylinder and two end caps. The end caps are drilled out to accommodate the seat rails of a saddle. This is really great for a couple of reasons:
ONE. It's very easy to get an ideal saddle position. The caps allow for almost unlimited, microtunable saddle angle. Simply loosen the caps and rotate the saddle and tighten the caps. Other seatposts can be much trickier, having multiple parts to align and position. Positioning the saddle fore and aft is just as easy to dial in which is great for people who are finicky about their saddle position.
TWO. The drilled out cap that cradles the seat rails offers a much greater surface area than most standard seat rail clamps. The seat rails on my saddle are horrible marred from years of use being pinched by the clamp on the stock seatpost that came with my bike. The wide gripping points on the Eriksen Sweetpost don't create pressure points like most seatposts. This is especially great if your saddle has carbon seat rails.
The Sweetpost post is constructed entirely from Titanium with aluminum seat rail clamp caps. The minimalist design is super light weight and reasonably indestructible. The ride is as comfortable as any other seatpost. You probably wont notice any difference in flex of the post from others unless you ride with a great length of the post exposed out of the seat tube.
Pros: Simply, clean design. Light weight. Durable titanium construction. Seat rail friendly clamp.
Cons: Seat rail clamp may not fit all saddles. If you are thinking about picking up a new seatpost, bring your saddle along to see if it fits into Eriksen's Sweetpost or call before ordering to see if your saddle will be compatible. If you are like me, you're somewhat married to your saddle and are unwilling to sacrifice comfort for a cool seatpost.
Ed. Note: Eriksen does make hardware for oversized carbon rails, customers should call to order direct for the non-traditional rails.
