engineering help? please?

[StratTuner]

Dear Friends,
I bought a set of these:



and the biggest bracket isn't big enough for an NC700x.
I'm disgusted with myself for not knowing what size to order or even how to tell what size the frame is so that I can buy a bracket at Home depot.
Help?
How can I attach these "freeway pegs" to my NC?
My own ingenuity fails.

restriction: NO drilling into the frame!

Wrap a tape measure around the frame to determine the circumference. Then go here and let it calculate the diameter for you.

Either that or get a cheap slide measure designed to give internal and external measurements. I got a plastic one for about a buck.

diameter times 3.1415927 = circumference
circumference devided by 3.1415927 = diameter

diameter times 3.1415927 = circumference
circumference devided by 3.1415927 = diameter

Might want to add a few more significant digits to Pi to ensure enough accuracy.

Strat,
Much as I hate spoiling everyone's fun with pi, according to my calipers the diameter of the frame tube behind the horn, I'm assuming that's the one you're asking about, is 1.4 inches or 35.5mm. Plus or minus .1mm, just to be on the safe side.

Ok... here's the problem I'm having... if I measure the circumference... I recall I get something like 4.5 (inches or centimeters... I will have to check that at lunch time).... now if I go to Home Depot looking for the correct sized clamp.... I should look for .... ????
I don't know..... I'm not sure how you buy these.
Math and I parted ways in 6th grade. We have not met or spoken to each other since.

 

[Mike Cash]

Ask a clerk to help you.

 

[StratTuner]

ok... i will do that... I just had the stupid idea that I would as you guys first.

Here, number 7942 works, you can either attach the pegs straight or buy a folding adapter.

I'll try to find a 1.5 inch bracket... if that's the one I need... I don't get why when I measure the thing and get 4.5 that translates into 1.5... should be obvious to me, I know but it's not. 1.5 it is then.

I think this is the item that will work, now .. the next engineering problem is ... is it strong enough to support 210lbs or less.
I don't expect to put all my weight on it, but I'd like to be able to.

Those look pefect! Thank you. .... wish I could afford them.

Why would you wanna do that, Strat???? I don't think you can even do it
In what situation do you see yourself standing on the highway pegs...????

 

[Spaceteach]

It looks like you would need something closer to 1 3/8 than 1 1/2. Also, if you think about how you will be mounting it I imagine the direction of force would apply a twisting movement to the cable clamp. If you mount the pegs using that, once you get it tight, push down on the peg and check for bending. My guess is the next step would be to pull up on the peg and try to straighten out the cable clamp enough to get the footpeg back out of it. Sorry to sound negative, but I doubt the clamp would be any where near strong enough to be safe.

[bamamate]

Those would be iffy. They are cable/hose clamps and are not designed to hold significant weight. I used them for the tool tube but that is only a couple of pounds.

 

[Mike Cash]

I didn't mean that as brusque as it appears in text form.

I just meant that once you know the diameter of the frame then a clerk in the store should be able to help you pick out some suitable hardware, as he will (should?) be familiar with the various items and options available at that store.

Didn't mean to sound like I was giving you the brush off.

The reason 4.5 translates into 1.5 is that practically every home has a tape measure they can use to measure circumference while fewer homes have calipers or other suitable devices for measuring diameter. You need to know the diameter because that is how clamps are generally sold....by what range of diameters they can accommodate.

 

[StratTuner]

You are quite correct! A safe rider NEVER would stand on the highway pegs.

thank you. I get confused between diameter and circumference. 'remember radius pretty well. 'Got some clamps at the store.. They aren't pretty, but I think they'll work.
pictures will follow since folks always like to see those.

 

[Bodysnatcher]

I'm wondering how the pegs mount on the new CTX models. The frame is likely very similar or maybe identical to the NCs? I'll need to drop by a shop to eyeball them but perhaps the NC's can use (some of) the stock CTX hardware. Probably the biggest con though would be cost since the plastics would need to be swapped also. Has anybody looked into this?

 

[StratTuner]

FAIL!

I couldn't make it work. After buying two sets of pegs, various brackets, and wasting about $60, nothing worked.
Sorry, there will be no pictures to show of that.
