Interesting. As I've gotten more experience, my saddle has gotten lower and lower. How far I move backward depends on how steep the descent is, which I think is pretty typical since the aim is to keep your center of gravity over the BB. On not very steep descents I can pretty much just hover above the saddle, while I've gotten tire buzz at some of the descents at Slickrock (which, in retrospect, I was probably back too far for). But if I'm back really far, I really can't pinch the saddle, since if anything, it's closer to my stomach than thighs. And I rarely mess with the saddle height on my main bike. No quick release and too lazy to stop mid ride and adjust it, so I just try to find a happy medium (at least until I pick up a Command Post, which will probably be a long time from now).

I think we are straying here; Zeo_Max is asking about paved road descents on an MTB, right? - - not off-road descending. Most efficient, aerodynamic off-road downhill tuck has already been proven to be the venerable "egg" tuck.

I am well versed in the egg tuck - arms and legs in at all times.

I do not think it is safe, if you hit 88mph you would end up warping back to 1955... though if the Libyan's are chasing you it is your call...

oh yeah! If I avoid descending to long (20 mile descents), my neck will nearly cramp tyring to keep my head up while riding the drops. Once I practice and do the ride a few times, it gets better. Justa s a long 40 mile descent wil make the triceps sore if you don't work up to it!

It's a little easier keeping the head up on the flats a there is less stress. Flying down the mtn at 40 mph for 20-40 miles can be a work out. Just as it is doing an MTB ride after a period of road riding. First couple rides back on the MTB after timeoff is a workout too. But after a couple weeks, the muscles are back in tune.

20-40 miles of this at 30-40 mph takes it's toll on your neck and arms. One of the main reasons I like to MTB, work on skills and prep the body to make these types of descents easier and more manageable. Really compliments road riding!


After climbing on a roadride like this, the 40 mile descent can take it's toll. Before I do this ride, I really work on training myself to keep my head up and work on triceps getting into form.

Haha! I've got the downhill down as far as roadbikes but on the MTB, I'm more of the Tome Jones type after getting bodyslammed on the hardpacked rocky stuff. 26% downhills aren't my thing since my MTB skills are lacking on the DH. I only do it for the climbing. MTB descending is much tougher than the roadie, even the little I do on firetrails improves my roadie DH skills.


But as far as music, this is my favorite. I talked my wife and an old guy friend into doing a good pace on the river trail so that I could use this song in the video. I like to crank this one up...warning: recreational roadie content.
