With two front wheels with 40 CM tires, the Avid BB7 brakes are all I
need. I've actually backed off on them so a full pull will not lock
them up until I've slowed down to 7 or 8 MPH. I prefer not lift the
rear wheel off the ground and slam the chain rings into the ground.

Nice setup for your vehicle. Hub brakes are always
dramatically more effective on smaller wheels of course.

The Catrike's front wheel hubs are very different from a two wheel
bike in that the wheels are only supported on one side. A hub brake
could be done, but not with entirely different headsets and wheel

Right, stub axle like an auto or many modern motorcycles.
Regarding braking, any hub brake (drum, belt, roller, CB or
disc) will have dramatically increased effect on a 20" wheel
compared to a 700C wheel.
This is very evident in practice, as ancient bicycle
mechanics demonstrated with Atom drum brakes on Schwinn
Krates, leaving long black marks on dealership tile floors
long long ago. Atom drum brakes are unimpressive at best on
a 700C wheel.
Even a band brake is snappy on a Panasonic 12" folder!

Wrong.. they're not the least bit grabby. Most of my braking involves
gentle modulation.
It can give at low speeds anyway an illusion of power, but I can-At imagine >> with the riding you do that you-Are remotely pushing the brakes hard.
A few years back I was averaging 17/18 miles per hour on 40 mile
rides. There were occasional road and highway crossings where I'd
hadn't planned on stopping but quickly had to stop. The first five/six
years on thr Catrike I often rode 60/70/80 mile rides on some fairly
hilly terrain, where, once again, there were highway crossings. On
some of those downhills I was doing over 40 MPH.
With the CatTrike weight static ie you can-At move on the seat back, when
braking plus the bulk of the weight forward Its not surprising that the
potential to lift the rear wheel is there.
Truth is that throwing the weight forward when the center of gravity
is about rear axle hieght makes it harder to lift the rear wheel than
on a two wheeler where the center of gravity is 20/24 inches higher.

Cable always is less modular than hydraulic nature of the technology, and
the fact you have wound them back says you do think they are grabby,
braking hard but on the edge ie keeping the tyre on the edge of grip with
the rear wheel trying to lift potentially is much easier with such systems.
And? ThatAs not a type of riding that will push brakes, nor will road useIt can give at low speeds anyway an illusion of power, but I can?t imagine >>> with the riding you do that you?re remotely pushing the brakes hard.

I keep hearing horror stories about leaking hydraulic lines

college, and both brake cables snapped. It was a very cold
day which may have made the cables more susceptible to
breaking.

That's not what happened.
Moving your bike from indoors (70F ambient) to midwest
winter commute (-25F) is insignificant to steel strength.

Right, stub axle like an auto or many modern motorcycles.
Regarding braking, any hub brake (drum, belt, roller, CB or
disc) will have dramatically increased effect on a 20" wheel
compared to a 700C wheel.
This is very evident in practice, as ancient bicycle
mechanics demonstrated with Atom drum brakes on Schwinn
Krates, leaving long black marks on dealership tile floors
long long ago. Atom drum brakes are unimpressive at best on
a 700C wheel.

Wrong.. they're not the least bit grabby. Most of my braking involves
gentle modulation.
Cable always is less modular than hydraulic nature of the technology, and
the fact you have wound them back says you do think they are grabby,
braking hard but on the edge ie keeping the tyre on the edge of grip with
the rear wheel trying to lift potentially is much easier with such systems.
Wrong... I have no trouble modulating them, but, originally, a full
pull would actually lock up both front wheels at way too high a speed.
When a dog ran out in front of me on a rather fast downhill I panic
stopped, stopping much quicker than I needed to. It lifted the rear
wheel off the ground and almost slamming the chain rings into the
ground. I backed them off to make them anti-lock like on vehicles, not because they were grabby.

Truth is that throwing the weight forward when the center of gravity
is about rear axle hieght makes it harder to lift the rear wheel than
on a two wheeler where the center of gravity is 20/24 inches higher.
I-Ad be very surprised if that is true!
It's a simple fact that raising the center of gravity makes things
easier to tip over. Panic braking on a standard two wheeler can
actually lift the rider weight up and forward.

I don't worry about hitting the chain rings on the ground, I simply
know that it's possible. It's actually much more common for two wheel
riders to lift the rear wheel when braking hard given the higher
center of gravity.

I'm pretty sure I've done it more times on two wheelers than on the
Catrikes, but granted I used to ride my two wheelers pretty hard and
some would say "carelessly."

So it's not too surprising to see hydraulic disc brakes even on lower

I keep hearing horror stories about leaking hydraulic lines on bikes

Moving your bike from indoors (70F ambient) to midwest
winter commute (-25F) is insignificant to steel strength.
But yes can be fair temperature change, on rides particularly if from a

The only thing IrCOm aware of with low temperature which can happen in the hills of Wales, is the diesel freezing in parts in the tank, which tends to make the lorry/bus cough for a while.
In other colder places I believe there are tank heaters to prevent this.

With two front wheels with 40 CM tires, the Avid BB7 brakes are all I
need. I've actually backed off on them so a full pull will not lock
them up until I've slowed down to 7 or 8 MPH. I prefer not lift the

It's a simple fact that raising the center of gravity makes things

actually lift the rider weight up and forward.
Since yourCOve claimed to worry about hitting your chainrings, which like >>> your legs are quite forward of the front axel of the CatTrike lifting a

I'm not sure what point you're trying to make. My single piston avid
brakes have served me well, and if someone gave me a set of hydraulic
brakes I'd put them up for sale. I've used the Avid's ability to
modulate to slow down on fast curvy downhills where equally modulating
the front wheels is critical. They're also capable of locking the
front wheels on a fullpull, although admittedly, my pull is probably
above average, which is why I backed them off. As for center of
gravity, my center of gravity is further forward than on a two
wheeler, but it's much lower and like I said, lifting the rear wheel
on a two wheeler is more common than on a Catrike.

With two front wheels with 40 CM tires, the Avid BB7 brakes are all I
need. I've actually backed off on them so a full pull will not lock
them up until I've slowed down to 7 or 8 MPH. I prefer not lift the

2/4 pistons or pad material and so on.
There is a healthy jump in just braking force, just going Hydraulic, after all plenty of 160mm road/Gravel and originally MTBrCOs but a larger rotor doesnrCOt appear to be enough to close the gap even if you installed 180 or 203mm rotors, and equally 4 pot callipers are most definitely more powerful again, larger rotors is one way to maximise power but the intended design will will have more impact.
It would be rough equivalent of going to 203mm rotors but considering BB7
And your vehicle notably has excellent rotor diameter to
wheel diameter!
is a old design itrCOs well over 10 years if not more, and that isnrCOt going to suddenly make it a powerful brake let alone the very front forward
weight distribution of the CatTrike.
Rotor size and % to wheel isnrCOt a huge difference, much more so is the brakes intended use and thus design.

I'm not sure what point you're trying to make. My single piston avid

brakes I'd put them up for sale. I've used the Avid's ability to

front wheels on a fullpull, although admittedly, my pull is probably
above average, which is why I backed them off. As for center of

on a two wheeler is more common than on a Catrike.

I have Sram G2 on my FS and Avid BB7 on my hardtail. Both have 180/160
mm rotors front/rear.
The G2s have decidedly more power, but also better modulation than the
BB7s. The BB7s have plenty of power (especially for a guy my size) and modulation. I'll take the bike that is better suited to the terrain I'll
be riding.

With two front wheels with 40 CM tires, the Avid BB7 brakes are all I
need. I've actually backed off on them so a full pull will not lock

Cable always is less modular than hydraulic nature of the technology, and

My Avid G2 180mm disks are over 4 years old with 9400 miles and I'm
thinking about replacing them at $41 apiece which puts them at or over
the average price for the standard six bolt disks. It looks like the
more expensive disks simply have a fancier type of attachment.

With two front wheels with 40 CM tires, the Avid BB7 brakes are all I
need. I've actually backed off on them so a full pull will not lock
them up until I've slowed down to 7 or 8 MPH. I prefer not lift the
rear wheel off the ground and slam the chain rings into the ground.
I swapped out the MTN calipers for the road versions so I can use Cane

What you?re describing is a grabby braking system, or one without much
modulation which is a generally a trait of cable disks. >>>>>>>>>>>>>>>>
gentle modulation.
Cable always is less modular than hydraulic nature of the technology, and
the fact you have wound them back says you do think they are grabby,
braking hard but on the edge ie keeping the tyre on the edge of grip with
the rear wheel trying to lift potentially is much easier with such systems.
Wrong... I have no trouble modulating them, but, originally, a full
pull would actually lock up both front wheels at way too high a speed.
When a dog ran out in front of me on a rather fast downhill I panic
stopped, stopping much quicker than I needed to. It lifted the rear
wheel off the ground and almost slamming the chain rings into the
ground. I backed them off to make them anti-lock like on vehicles, not
because they were grabby.
doesn?t do as you can feel the bite point and the slip point of the tyres.
Nonsense... locking up the wheel on a full pull is not the definition
of grabby brakes. Any decent brake system should be able to lock up
the brakes.
That?s why the old school roadie with its Rim brakes is more grabby than
even the MTB with its 180mm rotors which are levels more powerful than the
commuter bike with old hydraulic disks and the Gravel bike. >>>>>>>>>>>>>
And? That?s not a type of riding that will push brakes, nor will road useIt can give at low speeds anyway an illusion of power, but I can?t imagine
with the riding you do that you?re remotely pushing the brakes hard.
A few years back I was averaging 17/18 miles per hour on 40 mile
rides. There were occasional road and highway crossings where I'd
hadn't planned on stopping but quickly had to stop. The first five/six
years on thr Catrike I often rode 60/70/80 mile rides on some fairly
hilly terrain, where, once again, there were highway crossings. On
some of those downhills I was doing over 40 MPH. >>>>>>>>>>>>>>>>
in general, there is a reason disks started with MTB?s and even now have
larger rotors and 4 and even 6 pot brakes.
I don't think my riding pushes the brakes at all. That's why I said I

With the CatTrike weight static ie you can?t move on the seat back, when
braking plus the bulk of the weight forward Its not surprising that the
potential to lift the rear wheel is there.
Truth is that throwing the weight forward when the center of gravity
is about rear axle hieght makes it harder to lift the rear wheel than
on a two wheeler where the center of gravity is 20/24 inches higher.
I?d be very surprised if that is true!
It's a simple fact that raising the center of gravity makes things
easier to tip over. Panic braking on a standard two wheeler can >>>>>>>>>>>>>> actually lift the rider weight up and forward.
Since you?ve claimed to worry about hitting your chainrings, which like
your legs are quite forward of the front axel of the CatTrike lifting a
rear would seem much more of a thing, at least for that type of tadpole
design, the Adaptive MTB?s being used in much more challenging terrain the
weight is further back, and thus can have big hydro disks and so on.
I don't worry about hitting the chain rings on the ground, I simply
know that it's possible. It's actually much more common for two wheel
riders to lift the rear wheel when braking hard given the higher >>>>>>>>>>>> center of gravity.

I'm pretty sure I've done it more times on two wheelers than on the
Catrikes, but granted I used to ride my two wheelers pretty hard and
some would say "carelessly."

Yup modulation which is independent from braking force, yes hydraulic

Lifting a rear wheel slightly isn?t a problem, just the nature of the
technology.

That?s a lot of weight forward, the fact it?s got a lower centre of gravity
isn?t going to change that.
I suspect that cables are used for ease of folding and maybe cost saving?

Braking variables are dependent more on swept area (disc
diameter) than puck size or mechanism (cable/hydraulic) or
2/4 pistons or pad material and so on.
There is a healthy jump in just braking force, just going Hydraulic, after

It would be rough equivalent of going to 203mm rotors but considering BB7

My Avid G2 180mm disks are over 4 years old with 9400 miles and I'm
thinking about replacing them at $41 apiece which puts them at or over
the average price for the standard six bolt disks. It looks like the
more expensive disks simply have a fancier type of attachment.

180mm stainless rotor should be around $30, not $41.
(online prices run a few dollars under that but then again
you'd add delivery)
