A question on stem length
Hello to you,
Will appreciate your opinion on that
In the enclosed photo, the stem length (-17 deg.) is 120mm.
I got an S-works carbon **integral handlebars-stem** with a (-17 deg. too) 90mm stem.
Do you think I'll be good with this 30mm shorter one ?
Thanks a lot.

In your picture your arms seem to be at the right angle so I am not sure why you wish to shorten your stem. Are you currently getting pain while riding, if so where? We need more info in order to give a good response.

You look like a tall and fairly fit person.
In the photo, your position looks pretty good.
3cm shorter will definitely put you in a more upright position which puts more weight on the saddle.
Unless you have compelling reasons to do this, you probably shouldn't.

Thank you Doc V.
The reason I raised the qustion was mainly because I received (for free) this nice intgrated s-works bars and I wondered if I can use it in spite of the fact that it's a 90mm one.
I thought that my current 120mm stem is a bit (perhaps 10 mm or so) too long .
From your reply I understand that I better not change.
Thanks again.

Thank you andr0id.
I'm only 177 (frame is 54)
I guess what you and doc V suggest is right.
Will remain with current setup.
Thanks.

I look at:
- Line from eyes to front hub, if it passes well forward of the bar tops, stem (or top tube) is too short.
- Imagine rider is in the drops, forearms horizontal, body in a low aero position, really hammering, if elbows are well behind the knees (just overlapping is normal), then stem (or top tube) is too short.
By my rules of thumb, that stem + top tube is just barely long enough for you.

You could always try it out and see if you like it. I will say that your position on the bike looks good so long as your fore-aft of saddle has your knee in the right position. For help with fore-aft, Google Peter White and Steve Hogg both have good techniques for determining a good saddle position.
