Krzysztof over at GravelBikes.cc has been using his smartphone with a vibration meter app to compare the vibration absorption of different bike components on both a bumpy forest trail and fast gravel road. The eeSilk Post comes in a 27.2 diameter and is 350mm in overall length. Interchangeable elastomers allow the post to accommodate riders ranging from 100 lbs (45kg) to 330 lbs (150 kg). The best way I can describe spring seatposts is that they’re very springy! This makes them exceptional on off-road terrain, as they’re super responsive to bumps.

And finally, the air seatpost improved things a bit (6% improvement) but clearly requires a higher bump force to activate than other suspension seatposts. But the key difference to a carbon post is that the spring rate isn’t determined by how much exposed seatpost you have, allowing you to tune it perfectly to your body weight, using the five different elastomers available. But interestingly, data recently collected by the University of Exeter (England) suggests that once the seatpost is installed on a bike, it may not reduce vibration exposure.I’ve only gotten four or five rides in with the new Thudbuster, but I’m quite impressed. The redesigned seat clamp is fantastic, and I found the new elastomer system to work very well. Unlike some of the softer, coil-sprung posts, the new Thudbuster offers a nice mix of chatter dampening and medium-hit suspension to take the edge off of sharper bumps. And, it doesn’t feel as if it has as much of an effect on pedaling efficiency as other, longer travel posts do. Aerobars] How do aerobars affect my bike fit?This is a really important question, and it's one that we've spent a lot of time thinking about here at Redshift Sports, so get ready for a long answer! mm is common on older road bikes with drop handlebars. - There are other less common sizes that we do not provide shims for. However, other handlebar shim sizes may be available at your local bike shop. Suspension seatposts allow you to pedal while seated on terrain that normally requires standing up. Compared to a rigid post on the same bumpy climb, I find that my legs often feel fresher simply because I’m standing up less. Many of the popular models of dropper posts used on mountain bikes don’t work perfectly unless they’re setup correctly and well maintained. Fortunately, the RedShift post is far simpler and works smoothly every time with no special setup or care needed.

But there is a cost to this high reactivity. I’ve found that when spring posts are perfectly set up for rough terrain, they bob more than I’d like on smooth surfaces.Aerobars] Should I choose L-Bend or S-Bend extensions?If you don't have any previous experience using aerobars, we typically recommend the L-Bend aerobars because they put your wrists and arms in a more comfortable, ergonomic position. This is usually a better fit for triathletes and long-distance riders. If you're planning on using the aerobars for shorter, higher-intensity efforts like a time-trial, then the S-Bend shape can give you slightly more leverage to put out maximal power. If you ride a decent percentage on smoother surfaces or are sensitive to suspension bob, you will prefer elastomer seatposts as they’re less noticeable underneath you. Alternate method: Use a fabric or paper measuring tape (or print one at https://printable-ruler.net/ ) and measure the circumference of the steerer tube. You will need to remove the compression cap and loosen the two pinch bolts to get access to your steerer tube so be sure you are comfortable in doing so and then reassembling properly.
