Do any of you know whether or not taking off the crossbar will make them so weak that they shouldnt be ridden with? I figure it would make them the same as the fatbar. Am I right?

I want to remove it because I like the feel of the fat bar but I dont want to have to buy the fat bars. plus i have heard that with the bar removed it makes them less rigid and helps with the vibration.

It does, a lot of guys also just cut a gap in the cross bar so that they can still put the bar pad on

Well I just took mine completely off and put a fat bar pad on them that i had laying around.

I actually just got some in the high bend in a sweet red anodize. According to the little book that comes with them, it makes them weaker which is obvious. That's just about it.

I have three pairs of them and the first thing I do is take the crossbar off and throw it away. Much more compliant without it and besides I broke my nose on one of those wimpy crossbar pads years ago. No problems at all not using it...

Ran them a few years ago. Just saw the cross bar down the middle. Allows you to run the same bar pad and adds some flexibility (although not as much as completely removing the cross bar).

How the heck does sawing the crossbar in 1/2 not have as much flex as removing it?????? Unsure

And for the guy who has been through 3 pairs and always removes the crossbar, why not just buy fatbars?? Probably cheaper as well.

When doing this I recommend that you sleeve the crossbar with something that will keep it from turning into a sharp pointy object if your bars bend in half. Some might say this is excessive. But, how many times have you heard a story that of someone dieing in a crazy way that doesnt seem possible.

I, actually my cousin, just bent mine. It seems extremely ridiculous, but he was turning on a bank and back tire slide out and he isn't that experienced, so the whole bike fell over, but he had hold of one of the grips. The bike didn't really fall, it hit the ground and it actually bent one of the handles up somehow. Not that big of a bend, but they're still bent. They bend easy if you ask me. Damn handbook lies. ALL LIES!

Any of you that have removed crossbar willing to sell me one of the clamps that hold crossbar on . Apparently renthal doesn't sell them . They told me their glued on with special adhesive at factory to reduce vibration n won't sell me one without buying whole bar .

im not entirely sure im reading this right.. you guys saw a straight cross bar in half and leave it there? to gain flex? seriously? seems like a huge hazard, and a waste of money. Given the same thought, you would cut the expansion chamber on an akrapovic header because you "like the sound of a normal header" Unsure

They DO make fatbars, that are over $20 cheaper..Sorry Bayo, but you seem like you should be a little more knowledeable with this, bad advice dude. some dude takes a crossbar half to the eye and thats not good.

renthal obviously spen a lot of money engineering this bar, if they were asking for backyard answers for more flex because you get some stiffness in one random part of the track (that is probably from your shot suspension more than your handlebars), they would just tell you the obvious; buy fatbars.

This is a poor idea. You get a ton of flex and bending in the bars. The engineering is all off and your handling will be wonky (yes that is a scientific term). Buy a set of rubber mounts for the fat bars and hold onto your 7/8" bars as spares for the day you need a replacement set.

A lot of broscience in this thread...

I contacted Renthal about this and they said removing the crossbar is fine. They told me the difference in flex between a normal twinwall and a fatbar is 6%. When you remove the crossbar that difference is reduced to 1%.

Why not just put a 1mm cut on the bottom of the bar where it bends up after the clamp, the crossbar will stop it from bending too far and breaking. Laughing Silly

Buy a set of bars that suit what you want. They are something you don't want to screw around with.

Ive been taking the cross bar off my twinwalls for years. I called renthal and asked them and they said "Yes" you can remove the cross bar on the twinwall bars and that the bars are still stronger than any other bar on the market. People that doubt it just call them and ask there not going to say yes when they know the bar will break. I like to run the ktm factory high bend I believe its 994. They do make that bar in a "fat bar" but if I remember correctly the sweep or pull back was different even tho it was the same bar code. They still feel more rigid than pro taper or fat bars but they have a bit of flex now.

i wouldnt trust some sales rep over the phone, that still seems like an odd answer. i dont think the engineers at renthal had that in mind when they put it there. this isnt as simple as modifying an airbox for more airflow, you are compromising a piece of structural integrity. that picture above is a good example.

just think, renthal puts out "help wanted" ads for sales reps too. some johnny pencil pusher told you its ok to take the cross bar off and theyre stil the strongest bars on the market because he is paid to say that.

When renthal site comes back up you can see it for your self in the faq section.


Q 3: If the handlebar is so strong why does it need a cross brace?

A: The handlebar will run quite successfully without a cross brace. However, the addition of a cross-brace turns a very strong handlebar into an immensely strong handlebar.

I heard from a reliable source that many GP riders saw the crossbar in half like you guys talk about earlier, and keep the barpad because they want it to look like a twinwall, not a fatbar(obviously because its what renthal wants to sell these days).

Havent tried it myself (thinking about it though), but they say its more flexible and kind of reduces arm pump.. Dry

i remember seeing a pic of one of the tld bikes , in the pits , with the pad off the handle bars , and there is a sleve in the middle of the cross bar , were it was cut , and a sleve (pipe) over it , if u cut the cross bar dont just leave it with a gap , put a bigger pipe over it and tape it on does the trick , and u still get the flex ,
