Video: Seat up or seat down, what’s faster?

Maybe a dropper post is worth that extra pound…

Seat up or seat down?

To determine whether saddle up or saddle down is faster, GMBN sent former professional downhill racer Marc Beaumont down their test track to give both methods a try. They also compared his saddle up and saddle down times with a rider who prefers to run his post “in the correct position.”

Are you a seat up or seat down kind of rider?

    Been riding for 25 years and yep, I’m a grumpy old timer who runs a rigid post. I still have plenty of top 10s on the descents according to Strava and a few KOMs as well. Dropper posts aren’t for me. I think the main reason is that I also used to ride BMX and would pinch the seat with my thighs for stability when doing certain tricks and maneuvers. With a lower seat, I can’t do that and the bike feels all squirrely to me. I also don’t want to deal with the extra cost, weight, maintenance, or potential failure points with a dropper. For what it’s worth, I also run bar ends and inner tubes. I pass a lot of trendy bro-brahs just about everywhere I go. the gear doesn’t make you faster, skill and experience does.

    Agree with most of your comments, I rode for the first time with a Spec.Command post on a recent Trans Provence ride. In the very lowest position I was all over the place but in the mid position full control immediately returned as I also like to pinch the seat with my thighs,also this position did feel safer with a lower centre of gravity on the rough steep stuff though compared with full height. And yes skill and experience still rule.

    i think the most value part available today is the dropper post. it allows to switch the bike behavior, from a croos cowntry (seat up) to an all mountain (seat down). i used a cheap Tmars, untill it broke down, it made my bike much more on control, specially downhill. unbelievable sense of control, seat down, straight arms, rear wheel doesn’t lock, front brake doesn’t lift rear wheel. too bad it broke, rock shox reverb or KS Lev, my next acquisition.

    Yeah no shit guys. The issue isn’t just about faster though, it’s about safety. If your seat post is high, the second the trail gets technical, you are on your ass. Or possibly your face. I just can’t understand how you managed to find a rider who rides with the seat post up… then I saw the trail… ridiculously tame XC trail… yep, that’s just about the only place you can get away with your post up. No surprises there – the problem was in the test conditions. Move away from the bunny hill shenanigans and you will instantly see exactly Zero riders with their seat post high.

    Beyond that, using a dropper post is simply an issue of convenience. Do you do it with a lever or do you do it with an allen key. Nothing more needs to be said.
