You may be asking, is this really necessary? The answer: It depends. Lock-on grips have become ubiquitous, save for the relatively small contingent of gram counters who opt for foam grips. The problem with lock-on grips is that clamping a circling around another circling and asking it to prevent rotation requires a very high degree of clamping force — enough that a ham-fisted mechanic could easily over tighten the grip, causing damage to the bar.
Quality wordsmithing.
And no they don't."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

And what keeps the grip on the bar?
The wedge will just help slid the grips off if rotation starts."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

The grips still have a clamp - just on one side.And what keeps the grip on the bar?
The wedge will just help slid the grips off if rotation starts.By using a bar and grip designed with a wedge interface, the only thing the lock-on portion of the grip as to do is to prevent he grip from slipping off of the handlebar — a job that can be accomplished with much less clamping force.Framebuilder

And what if you need to cut your bars down?
Lock-ons are the existing answer to this problem
Edit: I have now read the whole article :oops: , and it seems there's a Park Tool to cut the bars. Hardly a standard home workshop tool though. So now we'll have to get a bike shop just to cut the bars down0 -
Then you just cut another wedge off?Framebuilder

Park tool are making a specific cutter for it that fits to their steerer cutter - unfortunately as its park tool it will be very expensive, LBS' may have it although I don't think it will be long before other companies make their own version.

So you buy the wedge shaped grips and the park tools cutter.
An angled piece of metal to resist the turning of a plastic/rubber object. Sounds like a cheese grater to me. Once the grips are worn, you have to replace with the same kind. I also think the method of locking will accelerate the wear of the grip.
Seems like a closed loop system.
I am happy to stick to regular lock on grips.
No major advantage other than trying to get money from people.
If you wanted to do it properly then you have a notch of the handlebars removed and the piece of the grip that fits in to the slot slightly over sized (use a rubber mallet to push it in home).
Like a cog and gear system. But you would still have stresses coursing the non clamped side to rotate.
Not for me.0 -
Or a simpler way.
Three preset drill holes in the grip that are countersunk and supplied with the correct size screws, tap and dye.
This would ensure no movement of the grip.
But I don't have a problem with the original, seems like another way to screw money out of people.0 -
Yes a notch would be better.
The wedge with just put a pulling force on the clamping ring. Moving it further out and allowing more rotation."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

I must never in my life have rode my bike hard enough.. Never had a grip rotate on me under any circumstance.
Can't imagine any instance during riding that would put that much rotational force on grips that isn't already a fubar'd situation either. Maybe I'm holding the bars wrong I guess.0 -

heat, moisture, terrain, force, pressure, manufacturing defects etc. It can and does happen. Extreme circumstances, depends on what you call extreme.
My thought is, this is not the solution, only a closed loop system.0 -

I own 3 bikes that take a regular grip, a trail hardtail, a 4x bike and a bmx. the 2 mountain bikes have lock-on grips, the bmx runs normal ODI longnecks. I can't recall a time where my grips have rotated or slipped.
A lock-on grip doesn't tie you into a 'system', there are many different designs out there , some with one collar, some with and as the grip wears you can rotate them yourself0 -
This looks like an effective solution to a problem, it's just not a problem that's ever been big enough for me to need solving. I have ODI lock on grips and they, so far, have been completely stationary.0

My experience with lock-on grips has been that they lock on - this is more than a little overkill to save people from the consequences of their ham-fistedness and I don't think it will work. If a grip is loose enough to rotate, it's loose enough to slide off the bar, and the angled end will just give it a bit of extra mechanical advantage to pull off as it's rotating. So . . . it will only work if it's locked solid by some external locking device or by grip glue. Very much like a lock-on grip, in fact. Maybe a better solution would be an insert that you glue into your bar ends, and you can put a couple of screws into it?Specialized Roubaix Elite 2015

I hate to agree, but I agree.Another solution to a problem that doesn't exist.
If you can't put lock-ons on properly, there is no guarantee you'll apply this lockring properly, or we could just resort to the old end cap technique and use an extra screw that points straight into the bar and creates enough of a depression to 'bite'.
I use foam anyway, lockons are far to heavy!Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0 -
Has anyone here ever had a problem with rotating grips? Or ridden with someone who has?
I have just never known it to be a problem. Not since I had non-locking grips on my Raleigh Burner back in the mid 80'sTransition Patrol - viewtopic.php?f=10017&t=130702350 -

It really isn't. A. because you either lockon or foam for weight B. It's not even a problem. C. You're locked in to a pointless expensive (relatively) standard. D. Not to mention the stupid cutting thing0 -

A. Irrelevant to the elegance of the solution. This is simply a third option.
B. It is for some.
C. Irrelevant to the elegance of the solution. Nor do you know how expensive it is.
D. Irrelevant to the elegance of the solution. And lots of people already cut the bars to their liking.
All I'm saying is, as an engineering solution, I like its elegance due to its simplicity.All the gear, no idea and loving the smell of jealousy in the morning.

But it's not simple.
Also cost. Bars and grips will be more expensive than my £5 lock ons that's for sure0 -
