Alternatively, most of the time a manufacturer will list this under their specifications in the Frame/Fork section. Make sure you are looking at the correct model year as these sizes can change year to year. The other main option to compare against would be an increased tyre size, which can also increase comfort when set at suitable pressures. Still, while this can be advantageous, it can also have downsides, such as slower rolling resistance in some cases and frame clearance in most gravel bikes.

Any bag that just attaches to the saddle or just attaches to the post is fine. But when you attach to both the post and the saddle you need to account for the relative motion of the saddle to the post. This means that if you cinch down the bag when off the bike it might have some movement when you get on the saddle and compress the post a bit - this might not be a problem but it might be something that is an issue.

All Rights Reserved Its parallelogram, spring-damped design allows around 20mm of travel, and although it won't take the sting out of larger impacts it does a good job of taming high-frequency vibrations and smaller jolts.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. It works in a subtle way, squashing sudden bumps and effectively smoothing incessantly rough surfaces. I found the recommended set-up ideal, but you can tune it to suit your preference.

While 20mm of travel may seem limited, the effect is instant and noticeable. While there is no direct comparison with other suspension stems, other forms of suspension are aimed towards the same market. Your Kinekt Stem comes with 3 different springs to adjust to your riding style and terrain. Easy to change! Comes with Soft, Medium (Installed) and Firm. BMC claims the torsional stiffness is equal to a standard stem and that you’ll only feel the effects of the suspension when it comes to smoothing out rougher surfaces. The stem comes with five elastomer rigidities that can be mixed and matched to fine-tune the feel. In total, there’s up to 20mm of tunable suspension. Best method: Use a pair of calipers to directly measure the diameter or take your bike to the local bike shop and they will be able to measure it for you.

Redshift ShockStop PRO Suspension Stem – Verdict 

Pros: Reduces road buzz and hand and arm fatigue, looks like a normal stem, 10 options of rise/length

This confirms the difference in effective travel, which is claimed to be 20mm on drop bars when holding the hoods and 10mm on flat bars. Its two-bolt saddle clamp remains level atop a parallelogram linkage pivoting on dry-lube bushings. When weight is added to the post a link compresses the internal spring(s), creating user-adjustable sag, which Redshift recommends should be around 20 per cent of the 35mm total travel. In general, you'll find the +30 deg stem provides a more upright, comfort-oriented fit, whereas the +/-6 deg stem puts you in a more performance-oriented riding position (standard for a typical road bike). Redshift suggests that riders up to 80kg should only use the main spring and those from 90kg to 110kg must install the inner spring as well. With the main spring fitted, my unit weighed 538g.
