SDG is one of the biggest names in mountain bike saddles, so it’s perhaps no surprise that it's jumped on to the dropper post bandwagon — though it’s taken it a little while.
I've had my hands on one for a short while, so read on for more details on the post and some early impressions.
SDG Tellis dropper details
SDG offers the post in 125mm and 150mm options, with both 30.9 and 31.6mm diameters. I have the 150mm x 30.9 option, which weighs in at 552g. The under-bar lever comes in at 36g. All-in with cables, you’re looking at a competitive 620ish gram set-up.
The post’s shaft is anodised, with height markings up its length, while at the base there’s a green plastic end of cable housing which gives a bit of protection to the actuation arm.
The lever at the bar is where the cable is clamped, with the nipple located at the base of the post.
The head of the post is 50mm deep, and it uses two bolts to secure the saddle. The collar is 25mm deep, and with the seatpost fully dropped, from base of collar to the saddle rail is 60mm — if you’re on the cusp of frame sizes, or aren’t sure whether you can fit a 150mm post, this measurement is important to note.
The overall length of the post is 440mm (150mm drop) or 390mm (125mm drop) though this doesn’t include the lower diameter actuator protector, which is 27mm deep and sits below the post.
Internally the action is controlled by a sealed hydraulic cartridge, which is replaceable — there’s a two year limited warranty too.
The infinite travel post’s internals are protected by wiper seals, SDG says they have been engineered for maximum performance. If you live somewhere chilly, SDG says it’s been tested to -20°C. The post will ship with Jagwire cables.
Initial Tellis dropper initial ride impressions
The first thing I noticed was that the post’s cable is clamped at the lever end. This is a massive plus point in my eyes, because setting cable tension and clamping the cable with a grub screw is approximately a million times easier when done at the lever end, rather than at the bottom of the post.
This means set up of the post took just a few minutes (once the outer had been routed through the frame’s internal routing — another story).
It did take a bit of faffing to get the cable’s tension just right. The lever has a very light feel and a slight cam in its action, so I had to use the barrel adjuster a fair bit to get it just right. I also found that the cable slipped a couple of times until I tightened the grub screw to a torque that felt more than the suggested 1.2Nm.
With the head’s bolts located close to the shaft, and not massively angled away from the shaft, adjustment with a multi-tool is a touch tricky. A ball-ended hex key makes life easier, but this is worth noting for on-the-fly adjustments.
In use, that light feel through the lever and a quick, but not wince-making, return speed means getting the post back to full height is very easy. There’s a gentle clunk when it fully returns, and as daft as it might seem, a light lever feel means you have to think about it less.
Through the first initial rides, I did have to adjust the cable tension a little. To get the post to drop, it felt like I had to press the lever further than I did for it to return, however I think a bit more fettling with the inner and outer cable tension would sort this out.
There’s no discernible twist in the post when riding, which draws no complaints. The lever has a decent length and some texturisation (yeah, I invented that word) to give extra purchase when pushing it — though they’re very rounded bumps, so I didn’t feel they added a huge amount of extra grip.
Initial Tellis dropper early verdict
Early impressions are good, but time will tell how reliable the post will be.
