Because of higher operating pressures, the longer Triggy Alpha remote is recommended to exert more leverage.

The most important task is to get a model that fits your frame. Seatpost diameters can vary, but most modern frame, to get the correct fit. Travel is either stepless, as with the Reverb, or fixed. How many settings does the Fox DOSS have? Fox recently announced the addition of a 175mm stroke length post to the Transfer lineup, which is compatible with the Race Face 1x lever, and the new post and remote will cost the same as the other length models. It’s great to see the 27.2 option if you are running a skinnier posted bike. Andy McCandlish / Immediate MediaFox has updated its reliable Transfer dropper post, reducing weight, insertion depths and adding a 200mm travel option. It’s also released a new 1x bar remote and has made internals easier to service. BikeYoke’s Divine is one of the best posts out there – the less sophisticated hydraulics make it a little cheaper, but more importantly, enables easy travel adjustment. The business end of the seatpost is its head, which has a clamp mechanism to attach it to the saddle rails. Measuring the circumference of the post and dividing by Pi is a good method. There are even circumference tape measures to do it.

supports the saddle, might be carbon on pricier models, but if you want to save a bit of cash, aluminium For a dropper post to work, there needs to be sufficient space in the frame’s seat tube. This is particularly an issue with smaller frame sizes, which often have shorter-travel dropper posts as a result. As with all aerodynamic upgrades in cycling, it is a culmination of marginal gains that will start to make noticeable differences to your riding. So, yes, seatposts can make a difference but, in most cases, aero seatposts will come in a proprietary design to fit a specific bike, making upgrade options considerably limited. Do carbon seatposts make a difference? The neat ability to twist the bottom activator out of the way of bottle bosses and other seat tube interruptions allows for maximum insertion. You can reduce the drop in 5mm increments using the included spacers. Although the Ascend II is impressively cheap, it’s almost identical to Race Face Aeffect-R and Syncros post. If you’re after a bargain, then, look no further.Concerted efforts have been made in recent years to further squash out the road buzz that can translate to fatigue over long miles. Reverb is available in two travel options, to allow those that need less drop, such as if they have a larger

Most seatposts are a lot wider than 15.75 mm. Machining the sidewalls down would weaken them tremendously in my opinion. There's the Canyon VCLS (it stands for Vertical Comfort Lateral Stiffness) seatpost, which uses a 'v' shaped split to create two thinner strips of material and thus disrupt the buzz from that nasty tarmac before it reaches the rider. Seatpost diameters are usually a multiple of 0.2 mm (but not always, as tables 1 and 2 show). If a measured value differs and most closely matches a value that is not a multiple of 0.2, there is a high probability that the closest multiple of 0.2 mm size will fit. For example, a measured 25.5 will most probably fit a 25.4 mm wide (nominal and measured width) seatpost. A rule of thumb is that the widest post that slides in without being forced (other than pushing or twisting by hand) is the right one. If it drops in, with play, before the pinch bolt is tightened, the seatpost is probably too narrow. If you don't feel your bike needs to be any more comfortable, and you're not fussed about 100 grams, then aluminium seems like a smart choice. If you want to drop the weight or add some cushion, look to spend more. Best Lightweight Gravel/Road Dropper: FOX Racing Shox Transfer SL 27.2 Performance Elite Dropper Seatpost

Most dropper posts enable you to lower your saddle by between 125mm and 170mm, while outliers start at 100mm and go as high as 210mm. One of the longest posts on the market, the Fall Line is light and loaded with great features, but we’ve had irritating leakage issues with our samples. There are a number of advantages to this, namely that the body of the post, which needs to cope with very heavy loads, doesn’t also have to be airtight and so lower-friction seals can be used for a lighter action. It is easiest to measure the existing seatpost outer diameter – if there is a well-fitting seatpost on the bike. In case there’s no seatpost, we would need to measure the seat-tube’s inner diameter (using calipers, and minding to measure the tube itself, not the seat-clamp’s inner diameter). might look simple, but there’s a lot to consider when purchasing a new one.
