Oversixe vs normal bar/stem(5 posts)

Oversixe vs normal bar/stemanzoni

Are there any big differences between these? I am thinking about Deda Magic, but see a lot of people use Newton/215 combination. I have ordered a Pinarello Marvel and think Deda is the right choice, but if anyone has suggestions, please tell me!!!

I have the Deda Magic and Newton oversized stem. I read some place that it's stronger and you're supposed to get better control/response, but TBH I'm not sure if I can feel a difference.

If you're thinking of getting an oversized bar/stem setup, here's a couple of things to think about. You'll find that most (if not all) computer manufacturers do not make mounts to fit around 31.7mm bars. I had to rig my Avocet with a zip tie and it worked fine, so that was a minor problem.

If you have or are planning on getting aero bars, your old ones will not work and your choices for new ones are quite limited. Deda makes one called the Clip 1 that fits and Profile is starting to come out with models that can be used on either standard or oversized bars. I recently got a pair of their Century aero bars that work great for me. (Check out my review at http://www.roadbikereview.com/Handlebars/Profile,Design,Century,ZB,Aerobars/PRD_28038_2498crx.aspx).

I was told by some folks at a LBS that Profile will start offering their Air Stryke for oversized bars in '03. I keep hoping that Syntace will make their C2 in an oversized model, but I haven't seen that happen yet.

One last thing. Beware of the Deda Newton stem. I haven't had any problems with mine, but if you read the reviews you'll see lots of complaints.

That's my 2 cents.

I think the logic behind oversized bars is to increase strength. But I don't know if this holds water. I have Deda Magic 31.7 bars/Deda Newton stem combo that came with my groupo and I really can't tell that much difference between that combination and the Icon/Performance Forte combo that are on my old bike. The oversized bars does complicate mounting a cyclocomputer, I had to go to a "Cronometro Nob" (Colorado Cyclist) that attaches to your stem. And bar tape does not go as far, you just have to be careful when you wrap your bars and not layer it too thick(however I have 46cm bars). I have not had any problems with the Deda Newton stem. I believe the problems were with the earlier models with a 3 bolt pattern. I've messed with my stem about a zillion times trying to find the right angle for my Campy Ergo brake levers. You just can't overtighten the ti bolts. If it was me, I'd go with the Deda 215 bars and Newton stem, just because of the computer mounting problem. Or you can rig up your mount using a zip lock tie as previously mentioned.

FWIW, I switched from an ITM Big One (110)/Pro 260 combo to a 3T Forgie XL (120)/Zepp XL and I immediately noticed an increase in front end rigidity, especially for out of the saddle climbs and sprinting even tho the stem extension was 10 mm longer. FYI, I'm about 175# and ride an oversized aluminum frame w/ carbon fork/alum. 1" steerer. Bar width remained about equal (maybe 5 mm narrower) with the new bar (40 cm). I have to shim the steerer to fit the 1 1/8" stem.

Also, my Cateye Mity 2 doesn't fit the bulge of the bar so I just jam it against the bulge as far as it will go and it generally stays until I hit some major turbulance and then I just push it back.

It's kind of hard for me to provide a clear description in the difference as the Deda combo is on my Colnago Master X-Light and the Icon/Forte is on my al Klein.

I like the computer mount on the bars as it's more visible, but the stem mount is tucked out of the way and you look straight down when looking for a reading.

I found that matching the Campy ergo levers to the Deda anatomic bars took a little bit more fussing around with for finding the right angle. But that is more of a problem with the ergo levers and not the Deda bars..
