This is my 2011 S2


I want to lower the bars, so far I have moved 1cm spacer to the top of the stem, and I wanted to go a little lower. Should I flip the stem or move another spacer?
The steerer is uncut.
Thanks

Move another spacer. Flipping it will have the opposite effect.

T2 - How long have you ridden it with the bars 1cm lower?

You do what it takes to get correct fit not for looks, why do so many people want to please others (flip it - slam it no mater what) rather that please themselves with with what makes you fit correctly on your bike?

It's already "flipped". If you want lower, either remove another spacer or bend your elbows more.

Do you have enough flexibility to go lower? Going lower will also extend the reach. It does appear there are too many spacers below the stem, put a few on top and see how it feels. Ride for a week or so on 50-100 rides and see how you feel. If you set up your bike to look pro but uncomfortable for you to ride, your bike becomes useless.

if you remove spacers, please level your saddle. Your junk will thank you for it.

Does this have a carbon steerer tube? If so, I'd try to remove a couple spacers. It's possible to damage a carbon steerer tube if you have too many spacers. I learned the hard way. Fortunately I didn't actually crack the tube, but it did have what looked like a crimp in the tube. I was able to drop the stem and cut off the damaged section of the steerer.

it's flipped, now slam that *****!

in what universe does this make sense?

Obviously you didn't look at the OPs bike

Probably 2 months, somewhere around 800 miles.

Yes, I changed the saddle and lowered the nose. Those first rides were brutal.

That's sorta what I'm trying to figure out here. The bike fits me well and is great to ride, so I'm guessing the next steps for me to take is to lower the bars bit by bit until- um- well, I don't really know. I moved two 1cm spacers so far and haven't noticed a big difference in the feel or comfort of the bike. Should I keep going until my back hates me? Also should I lower the nose of the saddle a bit as I move spacers?
That is a pretty old picture and the saddle is different now.

T2 - First, once your seat position is fixed, it stays there regardless of other changes. Other stuff can change, but seat position is a constant.

You've got 800 miles with the spacer out with no problems - cool! I'm guessing that's riding on the hoods. Have you tried riding in the drops for extended periods (>ten minutes), and if so, how did it turn out? If you're comfortable in the drops, you can either try going lower or just tack weld everything and call it good. If you're not comfortable in the drops for extended periods, you need to bump the bars back up until you are. It would suck having five miles' worth of headwind and not being able to use the drops the whole time.

Remember, this advice is worth exactly what you're paying for it.

I didnt see the OP saying any of that. Don't be overly sensitive where you read things that aren't there

If you want to go lower, remove another spacer, and think about having the steerer cut appropriately. Carbon steerers don't do well with too many spacers, on the bottom or on top!

Either way, killer looking Cervelo!
