UCI to ban supertuck descending starting April 1st.

I think it's quite intriguing and I had never heard of a dropper post before Saturday. I must also admit that I just cannot see the difference in his riding position even now when I watch the descent.

It's a bit more aero and allows for a bit better handling and cornering. But i agree that people are focusing way too much on mythical abilities of dropper seatpost. In contrary to the marginal ones. And rather giving the credit to the daredevil instead.

Its kind of interesting that people had never heard of dropper posts since they have been a mountain bike thing for quite some time now I assumed that everyone was aware of them. That's what I get for assuming huh?!

The first time that I used one I was amazed at how much faster I could corner (I can't imagine riding without one). Lowering your center of gravity even 100 mm makes a huge difference to CG I guess. My assumption is he or his mechanic decided to try one and they also found out how much difference a few mm can make. Lower CG and a little more aero might make up for a tiny bit of weight in the right race. They clearly had a plan, and it worked!

Off road they have other advantages too that wouldn't apply to road.

physics not mythology. He can clearly rail a bike quite well, but he wouldn't have chosen to use it if he didn't think that he could gain 'significant' time over using his standard post.

That plus likely he just wanted supertuck back.

P.S. I am sure that we will establish in the future on what attributes to lets say 95% and what 5%, When comparing dropper seatpost vs the rider.

A poor descender will never be a great descender by just dropping the seat 50 mm.

I think he only had a 50-60mm drop, so it wouldn’t be outwardly obvious, but it would give him a (marginally) lower centre of gravity, and a (slightly) smaller CdA. He only needed it to be enough extra to get a 10m or so gap. Once a descender like Mohoric gets that gap, he’s not coming back until you get the gang working together on the flat section.


As pointed out, the UCI have already confirmed they’re legit, but I can’t help thinking the end game of this is someone arrives on a World Tour start line somewhere with a 25cm seat tube and a 300mm dropper and looks utterly stupid, and the edict comes down to put the kibosh on them. Or at least limit them to 100mm or something.

The UCI approved them already (prior to this case).
"The UCI Equipment Commission approved the use of dropper seatposts in road cycling competitions in 2014. Their use is subject to the minimum 5cm setback rule of article 1.3.013 of the UCI Regulations, i.e., when the dropper seatpost is set to its highest or lowest setting, the saddle setback must be in full compliance with article 1.3.013."

I can't remember if it was Lance or JB that points out that it is already approved but nonetheless Johan asserts that it will be a goner. Take it for what it is I suppose.

If the dropper get too long they won't meet the the set-back rule so that won't happen.

Apparently already in 2014 already, and apparently Nibali had tried it out at spme point in 2017.

Back in the day it would obviously not be as appealing cause you could supertuck and Im not sure its faster tham pedaling supertuck, but this is great for cornering as well.

Imagine the gaps you could make as a great descender with a drop seat vs a weak descender without one on a hard 15km descent. Its massive.

The only drawback is the added weight for the mechamism but Im sure they can bring that down, if they even need to considering they can already get
bikes below the minimum weight

Also GCN guy only had a 10cm drop, which isnt the maximum

DT's lightweight XC model (60 mm drop):
