What's the difference in mx brakes

[Barney55]

Hi,

I might be sounding daft but what's the difference in mx 1000 and mx 900 brakes??
Which is the better brake?
Is there a difference between mx100 and  mx1000a???

Cheers

Mx 1000 is a larger calliper than MX900 ... I think some frames don't suit the larger calliper

What factory pilot said ^^

MX1000 have a longer reach than MX900 (10mm longer).

Can sometimes be issues with the brake blocks not reaching the rim properly for some frames tho.

This is a fairly common question and easily answered. On any DiaCompe caliper the number refers to the distance from the centre of the bolt to the centre of the brakeblock in the middle of the slot. You ignore the zero at the end and that is the dim in mm.

So an MX900 is 90mm and an MX1000 is 100mm. The MX means moto-cross and was developed especially for BMX with a stronger cross-section than previous calipers. The later DC FS880 caliper was specifically for freestyle frames wit potts-mods and has a lower top mout for the aduster to alow it to spin under the fram down-tube and yes, you've guessed it, it was 88mm center to center.

Similarly a DC 890 is 89mm, a DC1020 is 100mm and the 1080 caliper is 108mm. Going smaller to mini frames a 610 is hence 61mm.

Any caliper stamped 1000a on the back is not DiaCompe - it is a way of copying but not infringing the copyright.

Hope that helps

Thanks alot that explains everything

Just one more, which is better for mags and which for spokes? Or is it just personal preference

Freestyle 880's. Note the upside down/reverse pinch bolt location on the one in the foreground, in order to use a potts mod on the front brake

Personal preference in my case.

For looking at, it doesnt matter, go with what suits the bike/era/your vision, for riding with any kind of exuberance, dont bother with any of them, they're all wank

Major need for a stickie; perhaps with a very comprehensive answer.
It is an obvious question without an obvious answer.

[brimfull]

Great answer Spen, really comprehensive. Can you explain why 901s are so fook ugly though? 

[Spen69]

Aha. Now I believe that the DC designers and marketing team were on a ton of coke when those design disasters were born...... 

Gotta admit I get a bit of sick in my mouth everytime I look at them myself too

Phew, I thought it was just me. I remember running a back one on my Prolite and having to run it under the frame so I didn't stand on the stupid long brake arm when doing framestands  >:(can just make it out on this pic

Still think an illustrated stickie would be good and a fun thing but meh, that's me I guess.
May be I can try to make such a stickie, perhaps I will work on it. After all I am new to the site and perhaps less gaded and assuming. I could be a fun project I think.

[Andyboy77]

Found this stickie recently 

http://www.radbmx.co.uk/forum/index.php/topic,55863.0.html

Maybe we get this one going again? We could upload pictures of those mentioned calipers there and add the info.

I don't think that one is a great one to bring up nor a good one to build on.
Give it time for a considered response
