Without wanting to sound like a complete No-nothing-monkey. Why have we not got round to using disk brakes on NS bikes yet.

they do on MTB dont they?

yep, you can get disk brakes on all manner of mtbs now from super sh1t to super expensive.

so why not on ns bmx?

dunno, a lot of new school riders don;t use brakes at all, they'd most likely get smashed doing grinds and sh1t
and the market is maybe not big enough, and secretly even the the skinny jeaned new schoolers have respect for old school so they keep rim brakes.

ok, I honestly don't know.

Have a read of a book called bicycle design by Mike Burrows. All will become clear. Along with why the shaft driven BMX in this months BotM is a bad idea and many other such matters.

DB did it on a prototype racebike a few years back....Can imagine they`d be ok on racebikes.Atomlab did a cable disc brake kit for a while,it bolted on to a flip-flop hub.TBH I think that it`d be a change just for the sake of change.A well set up v or u brake can work perfectly.

People have put them on BMX bikes before.

But from a racer's perspective, they aren't necessary and are heavier/more difficult to maintain than a V-brake.

i think you could easily use a disc on the rear of a race frame......couldn't see it working on a park bike though......i understand they've made a hydrolic gyro to allow the use of them but i just don't see the need myself?

good caliper or canti brakes are perfectly adequate for bmx bikes as heywood said ^^^
tbh they are probably perfectly adequate for mountainbikes too

drum brakes were tried on bmxs back in the day, but proved to be a blind alley

pickle · « **Reply #8 on:** June 17, 2008, 02:19 PM »

Discs on MTB are essential due to the mud and water you ride through, try doing a downhill course with V's!

as for your NS bikes brake Keef......we can look at those at creation mate!

but just to get you started, make sure your cables are okay and oiled and also give the pads a good rubbing on sand paper to take off any gloss

thecrooch · « **Reply #9 on:** June 17, 2008, 02:20 PM »

you simply dont need them - i've been MTBing for 10 odd years now and some of the descents you come across if you didnt have em you would simply just die!!!

on a flat surface you just dont need em...

pickle · « **Reply #10 on:** June 17, 2008, 02:22 PM »

don't you mean "you simply need them"

like you say......on some of the decents i've gone down V's just wouldn't start to scrub off the speed you get!

Biggest problem with v-brakes on MTBs is pad life. I've worn a set of pads out in a day when riding wet/gritty trails or really big descents. Disc pads seem to last longer.

Compared with mountain bikers, we use our brakes a lot less.

kingkeef · « **Reply #12 on:** June 17, 2008, 02:26 PM »

This is turning in to a good discussion .
I dont feel like a twat anymore!

pickle · « **Reply #13 on:** June 17, 2008, 02:27 PM »

with MTBs you've also got the issue of dirt and water getting into the cables on Vs and effecting the performance, plus Mud on the rims/pads effecting braking performance. with Hydrolic discs you don't have to worry about water and dort effecting cables and the postition of the disc and caliper mean they very rarely get effected by dirt.

But don't worry Keef......you're still a prat

kingkeef · « **Reply #14 on:** June 17, 2008, 02:29 PM »

Thought so!

dialledbikes · « **Reply #15 on:** June 17, 2008, 02:40 PM »

I don't think hydraulic disc brakes would go down too well with skatepark owners either if they leaked hydro oil/fluid all over the ramps after a slam.

pickle · « **Reply #16 on:** June 17, 2008, 02:42 PM »

good point....christ could you imagine how slippery that would be! and corrosive too

Dark Diggler · « **Reply #17 on:** June 17, 2008, 02:50 PM »

On occasion I have ridden my 24" Jumpy at indoor skate parcs and on a track and it has a shimano rear cable pull disc with a DXR lever and its fookin ace, so much so that the hope brake I was gonna use is not on the bike. No need for Hydro's on a jumpy/trails banger.

that said I totally agree with others that on flat ground/ park/ track you dont need a disc brake although cable pull discs are an option. Personal preference if weight isn't the priority I guess

dialledbikes · « **Reply #18 on:** June 17, 2008, 02:55 PM »

I think we might see disc brakes on some race bikes in future (2 pot discs with really small e.g. 85/90mm rotors), but can't see them being popular on street/park bikes any time soon.

But the only advantage I can see is that you can run discs with a knackered back wheel as it will still spin without the rim hitting the pads.

stidds · « **Reply #19 on:** June 17, 2008, 04:16 PM »

Some of us already have a disc brake on our BMX.

Here is my Fetish Sin Cruiser complete with rear disc set up.

How trendy am I eh?

pickle · « **Reply #20 on:** June 17, 2008, 04:25 PM »

That's a single speed MTB!

dialledbikes · « **Reply #21 on:** June 17, 2008, 04:48 PM »

Stidds, is that a 110mm or 135mm rear end spacing?
