These could be the answer to all you riders that can't stand up properly.

they look like the go.......


if only i had old skool 7/8th bar clamps ??? ???


they dont seem to make ones for 1 1/8th bars >:(

I'm sure they will be able too

Is that eleven eighths?

I've heard it said the 8 out of 7 people don't understand fractions!

 ???

it says their good for clamping your over size bar,wow

It's a bit like "Two fists of F**k all"!!

Idiot!

 ::)

Don't you know 87% of statistics are made up?

At the bottom of the description!!!

Two models available – for 7/8” bar clamp using 7/8” for bars and for 7/8” bar clamp using oversized 1 1/8” oversized bars

I have sent them an email regarding size options and also to see if we can get a cheaper shipping option. Will post the reply when I get it.

And the other 13% is Bulls#@t

You were on the wrong site Pee Air - thats an off road chopper!!

I remember changing from fractured to metric and getting a calculator, Oh the joy of so much simpler calculations for drafting work. Try adding 3/64th and 5/16th and subtracting from 1-3/8th - I've got a headache already.

Ken, 1-1/64 or 1.015625

Well done Tim - go to the top of the hill.

Lets see how many more remember  (5/8 - 3/16) + 2-5/64

Here is the answer I got back from them.


We have the 1 1/8" listed. Search for listing #160321299043. We can ship priority mail it is slightly less expensive than express to Australia
- easyrider1111

(5/8 - 3/16) + 2-5/64 = 2 23/64 = 2.359375. But I guess it was going to 2/? to try and make it harder?

silly old nerds  :D :D :D ::)

that must be the same easyrider from the movie...... :D

that description says..."Model : For 7/8" clamps to 1 1/8" bars"


time he layed off the gear a bit ;D ;D

I hated maths in 1981.

I'm not interested in it now!

You young uns get life so easy. Fractured math was so much more cumbersome but we didn't know till we metricated, Ye Ha! Could never move to the USA, no wonder they are stuffed, and it probably explains why Harleys are Shyte.

Umm sorry Matt, but:

(5/8 - 3/16) + 2-5/64
= (40/64 - 12/64) + 2-5/64
= 28/64 + 2-5/64
= 2-33/64

Mat's still at the bottom of the hill!

Nup, at the top of the hill. 2 = 2 and (28-5)/64 = 23/64.

We'll have to go to the judge

Ken, is that dash meant to be a 2 And 5/64ths
Or 2 Minus 5/64ths

Ahhh, true guys.  Just another reason why imperial is a pain in the ass and metric is the way to go.  It's like 520 chain that has a different pin dia, hey Tim?  (what brand was that again?)

We could always move onto the standards for pipe sizes...
Nominal Bore,  Schedule 10, 40, 80... Then you have tube measured by the OD.  And all the different flange tables, grrr.  At least it's pretty rare to find anything other than Metric coarse or UNC in threads these days.  Pray you don't find Whitworth, I don't know what the Poms were thinking when they came up with that one!

"The Whitworth thread was the world's first standard, devised and specified by Joseph Whitworth in 1841. Until then, every industry had used their own screw threads." Ref Wikipedia.

So really it was a case of what were they thinking before Whitworth.

Mathematical convention has "-" as a minus symbol. A two and five sixtyfourths would be written 2 5/64 and to make it clear (2 5/64) would be better.

Of course there has been no discussion yet on units so we are no closer to knowing what size we are going to end up with.

In the drafting world with early typing 2-5/64 was 2 and 5/64.

Of course on the drawing it was 2 and then the 5 over a horizontal line with the 64 under the line.

Mat is right with no units being nominated ie 2-5/64" for inches of course.

And talking of course - don't forget we have Metric "fine" as well. But it's still better than a good mix of cross threaded - Whitworth, Imperial, Cycle, BSP,  Acme plus a few more I can't remember then metric thrown in to eventually dominate.

Mat I think you should be near the top of the hill if only for having a go.

Come on Boys it's about the Bar Risers, not a Maths Lesson.

Being from the old school & a chippy,when I measure a length of skirting or a noggin or what ever, I sometimes use both imperial or metric, for instance,.....1m & 2/78th ;D
Why you say, there's two reasons, one is, imperial is bigger & easier to read, & the other is my ruler is very worn & hard to read ;D but when I use my tape, it's all metric ;D

Looks like we got a rise out of someone ;D

So what your saying Ken is Mat is wrong and still at the bottom of the hill :P

I don't think Ken said that at all Tim  :P While mathematically correct I am practically wrong in terms of early drafting. Just as well we use CAD now.

Okay, just to make sure Mat is near the very top of the hill

 197/256 - (5/64 - 5/128 - 5/256) + 1 1/4 + (15/16(55-13+ 2/9 + 2/9 + 2/9))

Solve to the nearest whole number ;)

I get life the universe and everything!

Top of the hill Mat ;D

Hey Pee Air - did I detect a bit of a Dummy Spit?

No Dummy spiting here young Kenny, you and your Calculator mate's need to get back to the subject on hand!!!
