Lastly, we have air springs, which are sometimes used in telescopic seatposts. The main advantage is that you can adjust the spring stiffness to a higher degree of accuracy. Suspension Seatpost Designs

Until now, the Ergon seatpost has been specced on some Canyon bikes, known as the ‘VCLS’ seatpost. Russell Burton / Our Media If using clip-on aerobars on a regular road bike, it certainly makes sense to have two different saddle positions available. The RedShift Dual-Position Seatpost achieves this goal extremely well and is very well designed and manufactured.Maybe in the future RedShift could offer different versions of the seatpost to accommodate individual preferences and riding styles. In addition, the amount that the 5 cm change in saddle position makes to joint angles depends on saddle height, with the relative change being greater for someone like me who has a relatively low saddle height and slightly less for a taller person with a higher saddle. The reason for my preference is that on most rides I’m not typically able to stay on the aerobars constantly for long periods and then use the hoods and drops constantly for a long period. Instead, I fluctuate between periods when I’m mostly on the aerobars, but changing frequently, and periods when I’m mostly using the hoods and drops.

When I got the pre-load right for off-road terrain, I found there was more bob than I’d like on the road. Unfortunately, the pre-load bolt is not particularly accessible as it’s at the bottom of the seatpost, so it’s not an adjustment that you’d want to make too regularly.In addition to requiring a few more minutes to install and make fit adjustments, owners need to remove the post and clean between the leaf springs several times a season, especially if riding in wet and muddy conditions.
