Oversize bars-legit improvement or marketing hype?(11 posts)

Oversize bars-legit improvement or marketing hype?dawgcatchr
Aug 1, 2003 10:52 AM
HI. I am in the market to replace my stem to a different length-is it worthwhile to buy an oversize stem? I have been noticing that most new bikes are coming with oversize setups. I would have to buy new bars as well (not a big deal, with the 3TTT Zepp bars going for $40 these days). Should I buy the oversize stem, or just stick with the regular 25.8 clamp (and save $40)? FWIW, I am 150 lbs.
I think it depends on your weight...Dave Hickey

I'm the same size as you and I cannot tell but I'm seeing fewer new 25.8/26.0 bars and stems. They might be going the away of 1" steerer tubes..

I am 200 lbs and put some loads on the handlebar while climbing.
I used the standard 25.8/26.0 on an older bike I had and could really feel the flex in the handlebar at the mount.
On my new bike I've had for 2 weeks , it has a 3T Forgie stem and handlebar with the 31.8 OS .
I can truely say that I can notice a considerable amount of less flex while climbing that I did with the 26.0 setup.
So with me it has made a difference.
Luckily , the flightdeck I put on it has the mounts for 31.8.

They went with standard bars AND Aluminum stearers on their forks.

I can't say I'm all that impressed with the 3TTT Zepp. I find that the bar especially in the drops feels very weak. I can noticeably flex it just by using my wrist strength. In that respect the ITM Millennium OS or Deda Newton 31.7 is better. Currently I have the carbon Millennium OS which I like too. It's mega stiff compared to the Zepp. To be honest however, I don't the OS factor is all that important. In my opinion the bar design itself plays a much larger role in the over all stiffness or lack thereof.

...for what it's worth. The oversize stuff came on the bike. I was getting a new stem and bars anyway for weight-weenie purposes, but I specifically wanted standard size... really, really fed up with trying to mount computer, lights and, occasionally, aerobars on it. The computer just barely fit on at the bulge, but for the light bracket, I had to remove bar tape way down past the bulge and clamp it where one normally puts hands. For the aerobars clamps, I got some compatible but slightly longer bolts at Lowes which allowed the larger bulge to fit in a crude fashion.

As far as stiffness and whatnot, I can't say that I notice a difference. I'm slightly lighter than you at 140 pounds.

I suppose as the new size become more standard, gadget makers will make clamps to fit both sizes. I contacted the maker of my light (Light & Motion), and they claimed an oversize clamp was in the works.
At 150 lbs, stick w/ 25.8 barsTig

The oversize bars are good for bigger riders and sprinters who can put plenty of weight and power into the bars and cause flex or even damage. For us lighter riders, the good ol' standard 25.8 or 26 mm bars are just fine, unless for some reason we want a rougher ride up front.

I asked the same question in this board recently. I don't have a huge amount of experience with road bikes however here is my $.02. My Specialized Allez comp came with OS bar/stem combo and I am looking at changing the bar/stem to a Deda (Newton VS 215 with Newton stem to suit) setup. A friend recently got the 31.8 Newton bar/stem combo and I find the flex to be mostly from his Olmo carbon steerer! Whereas with my setup most of the flex seems to be from the bar itself (I have a alloy steerer) and the Newton bar feels really stiff. (I have an Easton CT-2 bar on my XC MTB and it flexes a lot!). I am only a light weight (145lb/64kg) and it seems in general the 26mm combo is lighter also so I am thinking of going back to the old 26mm std. I hear MTBs are going to 31.8 OS bar next year (04) also.... another marketing ploy?!

Make sure your computer has a mount for OS bars. I switched to 3TTT Forgie XL's and had to rig up a mount for my computer with a couple of zip ties. Otherwise the computer would have had to be mounted almost 2" to the right of the stem.

Just something else to think about.
