Description

Bombproof reliability.

After two years of extensive research and development, SDG Components introduces the Tellis Dropper Seatpost to eliminate the pitfalls in reliability and complex servicing inherent to many popular dropper posts on the market. That means you'll be able to ride your Tellis Dropper without worrying about constant servicing or bleeding requirements, even in the most extreme conditions. SDG did their homework in the lab by subjecting the Tellis Dropper Seatpost to a self-contained vat of muddy grit and moisture for months on end, finding it remained clean and fully functional without moisture and dirt ingress sacrificing its ability to drop and return upright in a smooth, speedy fashion.

SDG didn't stop there, deciding it's best to bring the Tellis into real-world conditions most riders will subject this dropper to over time. Their secret shed in Kamloops, British Columbia served as the perfect location for testing a dropper seatpost, seeing Kamloops sits in an area that's prone to short cold snaps down to negative four degrees Fahrenheit (that's negative 20 degrees Celsius for you Canadians). This is a huge benefit for riders extending their season through late-autumn and early-winter months where colder temperatures usually make for sluggish dropper post performance or ill-functioning when your dropper fails to return upright.

Delving into the construction of the Tellis, the robust 3D-forged head is sleekly appointed and stronger than bonded heads found on other dropper seatposts. Inside the post, you'll find a sealed hydraulic cartridge system that's both extremely reliable and easy to service or replace down the road. Also, SDG uses an intelligent keyway system that eliminates lateral head movement, plus a wiper seal that keeps muck, grit, and moisture from seeping inside and ruining your dropper's performance. It's completed with a scratch-resistant anodized finish and laser-etched graphics for dialing in your saddle height.

Please note, the thumb actuation lever mounts on the left side of your bars and works best with 1x drivetrains (it may get in the way of older 2x/3x systems with a left shifter mounted to your bars). For installation, there's a relatively painless attachment located at the base of the Tellis Dropper, so you can quickly connect, then route your cable through the frame. Routing is internal only, meaning it won't work with older frames lacking internal dropper routing.

Reliable Performer

  • Familiarity: I've put it through the wringer

The best thing about this post is that I nearly forget that it's on the bike. And isn't that really the point, and a prime indicator of a great component? It operates seamlessly, with reliable actuation, and has not required any maintenance. Definitely a solid effort from SDG.

Probably the best deal on a dropper

  • Familiarity: I've used it once or twice and have initial impressions

This dropper was extremely easy to install. Seems to be build very strong. I was a little worried about the return speed as there isn't any adjustments that I can see. However it's perfect. I like a rapid return and this provides it. Now if you like a slower return you may not like this. My previous dropper was a hydraulic hose/lever and I'll never go back to that headache. The cable actuated lever is the way to go for simplicity as well as functionality. It is as claimed "effortless and smooth". It even comes with the post and you don't have to order it separately. There's enough housing to fit any bike with a lot of extra. Even has the ferrules and a black cable end crimp. Let's talk about the saddle side to side rotation.... SDG claims there isn't any but there is. Naturally there has to be a little for it to work as you would imagine. But, it is soo slight you'd hardly notice it when moving it with your hands, sitting on the saddle you will never feel it at all. Really, it's that good. I am super impressed with the post at a very affordable price tag. I'd be surprised if they don't go up on price when riders find out how good it is and the demands increased. I was planning on spending near double until the SDG was recommended. The ONLY thing I had a small problem was getting my saddle installed as the clamps are a very low profile. Not really a negative because once it's on.....it's on and looks great. Highly recommended whether you want to spend a little or a lot. But all I can say is it performs as good and even better than some higher priced post. I've been ride for 30 years and have been a bike mechanic for many of those so I'm not now to high/low end components. You'll be pleased and glad you saves a few dollars.
