Asymmetrical surfaces on brake pads, which mounting direction?

Hello Folks,

The Promax Decipher brakes on my MTB use Avid BB5 compatible brake pads.
Could not get the ceramic-based ones and the new semi-metallic pads are
shaped asymmetrically:

I asked at Amazon and another customer said he mounted them with the
wide part towards the back. I thought the narrower part goes back so it
wipes dirt out of the way as the disc wipes through, like a
rear-pointing arrow.

Does anyone know which direction to mount them? Do they brake as well as
the old style pads which are symmetrical and have a little more surface
area?

That's what the customer at Amazon also said. What is the reason for
mounting them this way?

Yesterday I almost was for a few seconds. Came down a hill, singletrack,
flooded section, no way to escape, dodge or stop ... *SPLOSH*

Oh we had fun!

Lucky for you the trail under that water wasn't washed out or there wasn't a hole there or you might have had a serious flying header and a long walk home.

Why do people ride at a high rate of speed into areas with no sight lines or blind corners where they can't see anyone who might be riding the opposite way? Do thet think that no one but themselves ride that area? I've seen a few accidents and near accidents that were caused by some bicyclist riding at high speed in an area where they couldn't see much and thus had no time to either react or avoid the other bicyclist. The near accidents didn't happen because at least one bicyclist was riding according to the conditions at thetime.

Riding at speed around a blind corner and then scaring a mountain lion is not a good thing. The reaction the cat might have might well be extreme.

Cheers

Another rider did but landed softly, mostly in mud.

Yeah, I know, I know. It's a section that is normally never flooded or
even muddy so you can almost stop on a dime. Just not yesterday. Then
you have two choices:

a. Brake by going into a sideways slide and possibly end up in the
drink, after which you and the MTB will look like dunked in melted
chocolate.

b. Decide to go through (which we did) and, well, plow through.

They hear you coming from far away, then make their decision wether to
stalk you or not. They prefer to stay away from people and usually
skedaddle in time. Brutus the bull OTOH ...

The recent rains have washed the roads clean. On my ride yesterday I crossed one drivel of water across the road. In was only an inch or two wide. I slowed to almost stopped crossing it. When I got home the bike was covered in mud. The world ain't fair.

The manufacturer of my MTB thought white is a good color for an MTB. No
idea what has befallen them to think that. I found that it won't get
more dirty after a certain "yuck level" and to me that yuck level is
acceptable. My wife has a very different opinion.

My road bike isn't all that clean either. On almost every ride there is
that mile or two of offroad stretch and no matter how carefully I ride
it gets dirty. So I stopped washing the raod bike as well until some
major repair needs to be done.

the colour white is universal for stressed vehicle coatings.
