[Closed] When will ABS brakes for mountain bikes be invented?!

ABS and off-road conditions isn't a winning combination

Edit: plus skidz r cool

No it won't. ABS isn't that quick to respond that it wouldn't stop wheels locking up on loose surfaces.

Sometimes you just need to skid (eg. to impress ladies).

they already did

I'll have a go at inventing anti lock disc brakes just as soon as I've finished this packet of chocolate digestives.

Hope brakes have ABS as standard don't they?

There was an early version i saw yearssss ago that had a ring drive around the front hub that was like a ABS ring on a car, this has a teeth cog running into it which ran a pump to cause the pads to flutter in and out.
it was cool.

I suspect that given the formation mechanism of braking bumps, ABS is likely to make them worse.

Eventually the bump becomes a berm, removing the need for breaking and returning fluidity to your ride.

When they have finished selling us different wheel sizes and the 1 x 18 transmission.

😆 at

1 x 18 transmission.

ABS would make sense on a road bike but it just wouldn't work properly on a mountain bike I'm afraid skill is key...

yeah right, they'll be reinventing the wheel next..............

Doesn't everyone pulse their brakes anyway?

Why don't you just bring a spade next time you go to your local trails and fill the holes in?

I know on my old big enduro motorbike you could switch the ABS for when you were using it off road, so don't think there can be an advantage on an MTB, i prefer being able to modulate the brakes myself, any system like that means you tend to lose a bit of the "feel" of what is going on.

Thanks for the answers guys!

Apart from the fact that they already have, and the fact that ABS off road is not exactly a great idea, what is wrong with braking bumps?

They're as much a part of trails as roots, cambers, rocks, holes, steps, puddles, ruts etc.

Badly thought out and/or built trial = braking bumps.

P.s. The day bicycles evolve to include ABS as standard is the day i give up on bikes.

Artificially compacted ground is pretty poor compared to naturally consolidated material unless you can give it a good going over with a wacker plate in the right conditions.

Generally I prefer to take off the tops rather than backfill, but that's not always an option. Same with bench cutting. Its better to slice off the top to the new profile where possible, instead of disturbing and back-filling.

The game changes when you're dealing with blended standard aggregates, but even then, braking zones are always going to suffer wear. Sometimes a tweak in the trail further up to reduce approach speed, or re-working the corner a bit to reduce the need for braking so hard can combine to produce something a bit more durable.

Badly thought out and/or built trial = braking bumps.

Negative. You can have a really well built trail but if a load of spanners come piling down slamming their brakes on and skidding all over the place its going to knacker the trail. Unless a well built trail = tarmac?

It would be the most durable, but obviously rubbish! This is the problem with trails and usage. There's a constant balance of conflicting needs, and these are constantly changing.

Long time ago there was a braking bumps thread on here and someone scientificcy showed that the occurrence of braking bumps offroad was about the slowing of the wheel and would still occur if no one locked up.

Go and ride your mountain bike in some proper mountains where there are no braking bumps?

Watched some motocross the other day.
The track had bumps.
The riders used their skill to use, jump, or avoid them.
They seemed to be enjoying it.

Did you try using your skill to use, jump, or avoid them?

It might be fun.

Otherwise, well, kinda wonder why you're on the dirt, really, if you wouldn't find that sort of thing fun.

Antilock brakes were very common in my day. Simple mechanism that always worked in the wet - you could rely on your bakes not locking.

I'm not sure we're ready to go back to rod brakes even though shiny chrome rims look ace. 🙂

I'm always doing that. Over the weekend some pretty big bumps appeared. I don't know. Maybe cos we've just built it and it's not compacted enough.

Badgers or moles?

I don't know what braking bumps are! 😀

these, basically the bumps you get into a corner after (normally) a fast approach to it.

I always thought that it was full sussers that caused them, with the riders weight being too far forward so the back goes light and skips.

When cornering I try to hang my arse out the back in attack position to weight up the rear and use gentle progressive braking front and rear to dump as much speed on the straight so I'm slow in, fast out - But then I fairly sure my technique isn't best. Get the line through a corner right and it "should" have a slingshot effect on a descent.

I find most of these bumps tend to be bang in the centre of the trail and normally not on the right line for the fastest and/or smoothest route through it anyway.

EDIT

Well the line [u]I think[/u] is faster anyway, oldfart rally driver habits are hard to shake.

Speaking of rallying, the first item that gets binned in a rally car... yip the ABS relay / fuse, ideally you "steer" a rally car on it's brakes on gravel, the braking system effectively makes up 50% of the direction changing apparatus.

I find the exact opposite. Weight pushed forward and down, heels pushing down and hips following the turn. You can't steer with the rear wheel.

The initial formation of the bump 'may' be due to some braking but it's exacerbated by suspension and once the formation of a bump starts then any riding will make it worse.

As the suspension cycles over it, the pressure wave will shape the ground around it

Just learn to manual over em and brake beforehand

Afaik braking bumps can occur in pretty much any surface, I've seen it on Tarmac road and read that train tracks can get it as well. I have no way of explaining it though:)
