Since measuring often can’t be done to a 1/100 of a millimeter in accuracy, the next section gives a list of the most commonly used standard seatpost diameters. If a measured diameter differs, it can be assumed that the correct diameter is the standard one that most closely matches the measured diameter. shaft is lightweight, and many will have a natural flex built in which helps dampen road buzz, making it The most important task is to get a model that fits your frame. Seatpost diameters can vary, but most modern

There are two travel styles for dropper posts: those that have fixed height settings where the post stops (20mm down, 75mm down, etc), and those that do not, often referred to as stepless or infinitely adjustable. At 300mm in length, the Enve seatpost is available in 0mm, and 25mm-offset versions. While quite a few carbon posts have a metal clamp head bonded on the top, the Enve post is carbon through and through. A more modern trend, mostly on mountain bikes, where stronger seatposts are required (without too much extra weight) led to a new “oversized” standard of 27.4 mm (and wider). Finally, there are a number of ‘non-standard’ seatpost designs worth mentioning, the primary ones being aero posts (for road and TT racing) and dropper posts (for trail and gravity MTB riding). When it comes to cancelling vibrations, there are several steps brands take to aid this in frame construction: using thin seatstays; placing the seatpost clamp lower down so that more seatpost is exposed (allowing for more flex); and using a narrower seatpost A carbon seatpost is effectively an additional step; a cherry on top.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.

As far as we are aware, the BikeYoke Revive 2.0 is the longest dropper post on the market with 213mm of travel and a 582mm max length in its biggest size, which is good news for those with long legs. Measuring a seat tube diameter is often necessary before purchasing, or changing the seatpost. How should one do that? Three methods will be explained here, but one can always be creative. 🙂 But, a narrower pipe could probably be sourced, or even a steel rod – then it’s up to finding a turner to process it into the appropriate diameter size. Whichever type of post you’re considering, you’ll need to decide on diameter, length, offset, clamp type, and construction material. Diameter is the most critical of these metrics, as it must be the right size to fit into your bike’s seat tube. The most common diameters are size 27.2, 30.9, and 31.6mm. Narrower diameter bike seatposts can help smooth your ride due to a minimal amount of flex, while wider ones are usually stiffer and thus enhance power transfer. If you do happen to have a seatpost that’s too small for your bike you can use a shim, but of course you can’t go the other way around.

Upgrading the seatpost on your road bike is a great way to lose weight and potentially add some comfort too, The most common size on modern road bikes and gravel bikes is 27.2mm. These posts can be found on some MTBs too, although the size is confined mainly to a limited number of cross-country mountain bikes. cradles, have a minimal effect on performance. Changing a Seatpost for Comfort vs Altering the Bike Fit

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.

If you use a carbon seatpost, make sure to fit it using a thin layer of carbon paste as this stops it slipping. Pay attention to the quoted torque at which you should tighten the bolt - overdoing it can cause it to snap. If you don't own a torque wrench already, here you can find our recommendations for the best torque wrenches for bikes. Road and gravel bikes tend to have a longer seat tube than mountain bikes, so usually requirer a shorter post of around 300 to 350mm. Mountain bikes typically leave more of the seatpost exposed above the frame, so require a longer post. The post comes with a shifter-style under-bar remote and internal cable routing, unlike the regular Ascend (also included in this guide), which has external routing.
