Bicycle Mechanics - -25 degrees too much of a drop for a MTB stem?

Hello Everybody,

I'm thinking of flipping my stem upsidedown so I get a drop instead of a rise from them. If I did flip them, I would have a -25 degree drop. Is this too much for a MTB? Should I invest in a +/- 7 stem instead??

To put it that low will make your endo-point more sensitive, but your climbing and aero(if flatlanding/roading) will be better. 7-10 negative are a little more normal, but stem angles/extensions are a subject of personal taste ultimately. If you try it and like it, then it is cool. End of story. If it is not satisfactory, then continue experimenting.

That will be a drastic drop. ....and not to mention aesthetics, if you care, a bit odd looking for a mtb. A 10 degree stem is flipable without such a radical change in riding position.

Thanks.

Not following the rational-lower CG. Can you elaborate?

With such a drastic drop, he'll be leaning down/forward more, with CG much closer to the front wheel.

I'm wondering if the stem would actually clear the front of the headset.

Quite a few will. If it doesn't, a small spacer under it is fine.

Lots of speculation; why not just try it and let us know how it worked.

If you don't like it, switch it back; no?

My thoughts exactly.
