Research - 4Bolt Mount Measurements

[hydroboy]

Gday, Im doing some research for the plaz man as he is looking at making some decent 4-Bolt - Vee Adaptors. I was wondering if people could measure the distance between the bolts for the brakes, if you know what i mean, as he is looking at having an integrated booster which runs underneath the brake.

The measurements he needs are:

A - Distance Between Top Bolts
B - Distance Between Bottom Bolts
C - Diaganal Distance ( Used as a cross reference check)

Below is a shitty diagram of what i mean.

Give me a shout and I'll let you have a look at the drawings of my home-made ones.. Two piece, very solid and quite easy to make...

edit, btw, its not the ones in my avatar. Those are the first i made.

A, B: 102mm
C: ~112mm

Identity sort of has one going, and I know a rider who is using it on a PX Tibo, so they both have the same spacing.

Don't the bikes have different dimensions depending on which manufacturer makes them? Or, are all of the bikes with four bolt mounts the same? I thought they were different.

[tomacropod]

surely that's part of the purpose of this survey - to find out the answers to your questions (bwagner).

[hydroboy]

That was the idea of me asking the question. To see what the differences are...

Also could you say what frame you are talking about, i think i can guess yours RomanR :P

edit damn you joel

[tomacropod]

you are really up much too late Alex, I'm concerned about you. Are you having troubles?

[hydroboy]

well its 8am now. didnt go to bed last night. last day of school before test week, assignments due blah.

[B1105]

you have school now? are you a college kid or a high schooler

[tomacropod]

he's what we call a "college kid" which means he's in year 12 (I think). Here College != University. High schooler to you.

PV - what you need to get you through those long nights is dark chocolate and coca-cola. Milk chocolate will put you to sleep, dark chocolate is where izat.

those look totally farken shweeeeetttttt :hsugh: ... but i already have v-mounts :wiggle: ... and you could run like 3 seperate boosters on that thing, plus the booster shape of the actual thing. lol. im a dickhead. :wuteva:

[Matt]

I agree, that is by far the nicest looking 4bolt -> 2bolt conversion I've ever seen.

[hydroboy]

Well i havnt seen that before, i like how adjustable up/down it is. It is what i meant when i said integrated booster which is why the length from side to side is a problem.

Is there any one out there with a monty or somthing different? Brisa? whatever...

[Bloodhound]

you could take that awesome adaptor, and cut the top off so you just have the two sides = perfect magura > vee adaptor for all bikes.

[trialsmasta]

Speaking of off the shelf adaptors, who besides woodman and identity make them?

[besham]

"you could take that awesome adaptor, and cut the top off so you just have the two sides = perfect magura > vee adaptor for all bikes."

That sounds like the best idea to me, then you could just use the standard magura booster on top and a regular vee booster if your into overkill (as I am)

I dont have my monty frame right now, but it was at the very limit of the magura booster if that helps

[Janson]

I like mine.
