The Ultimate Brakeless/Front/Rear/How many brakes? thread

I can beat that- I failed my cycling proficiency due to the condition of my bike as the brake pads were "insuficient to the task of braking".

11 years old and already running Brakless- feel me.

im sorry that you feel like that joe,

tell you what... why dont you do what i have done in academia while english is not your first language... then you can talk to me about something i have said or sone wrong...

and here is something for your no doubt un-educated self...

"we ought not to be embarrassed of appreciating the truth and of obtaining it wherever it comes from, even if it comes from races distant and nations different from us. nothing should be dearer to the seeker of truth than the truth itself, and there is no deterioration of the truth, nor belittling either of one who speaks or conveys it" Al-Kindi

un-educated? HOW VERY DARE YOU!

i have
5 gcses (a-c)
a btec in topiary
an nvq (level 2) in basket weaving

so there.

I never dun da skoooollling, but I no how too use a hamer!

Hillbilly is a tool.

Sorry I meant mechanic.

Touch my face!

OH SORRY!!

FAIL!!!! on my part.

Shut it popeye.

I'm an engineer DONT YA KNOW!!!

The point isn't that some riders will be able to ride a particualr setup safetly. The point is that some cretin who doesn't know any better may see this list and assume that it's correct. Thereby putting themself at risk as they are on a bike which they are ill equipped to stop.

Can we get a fucking hallelujah here!

God damn It children.

perfect day to ride a bike?

post crap online?

perfect day to ride a bike?

post crap online?

Some of us have to work, in-fact I'm still in my studio working...

Awesome. Perfect. That's exactly the response we were looking for:

Object, "Where's you proof? your workings? your citations? I just want to see how you've arrived at this supposition becuase as far as I can tell you've just written a list then claimed it as scientific fact!"

dr.metal, "Snowflake?"

Object, "great, thanks for the insight".

paging Tynan, you are needed on thread 17566

Just come across this thread.

This, does NOT make sense.

Ok, anyone mind if I throw my two cents in?
Assuming 100% brake efficiency (locked wheel), a skiddy will eventually stop whereas a SS front brakey will faceplant.
However, asuming maximum utilisation of the available friction coefficient (mu) then a SS brakey will have a shorter stopping distance:
The effect of braking tends to try and make the bike rotate around the front axle, so if the rider modulates the braking to prevent front lockup then there is a mass transfer to the front wheel (after all if your back wheel is off the ground it isn't carrying any mass). So the force per unit area on the tyre contact patch is increased hence the normal force is increased and you end up with a higher effective mu (kinda like how F1 cars corner at 4g, only they use aerodynamics).
A fixie skidder has to transfer mass to the front in order to unload the rear so less mass per unit area and a lower effective mu.
Higher mu gives higher rate of deceleration from a given velocity and mass.
I can't be arsed to type out the math but it works.

All the arguing about physics is pathetic, here's a formula for you:

Freewheel + front + rear brakes = Correct.
Freewheel + front brake only = For twats.

Mu doesn't change regardless of how much you brake.

Apply front brake>weight transfers forward>front wheel is forced against the road surface in relation to weight transfer = braking efficiency increases (usually to the point where you need to move weight backwards "manually", if you see what I mean)

Mu Mu!

What time is love?

Mu doesn't change regardless of how much you brake.

Agreed, but effective mu (as an axpression of the normal force in play) is a good easy way of explaining it.

And also agreed: Frewheel brakeless = Dawin's theory at work

anyone who tells another how stupid their set up is, without knowing them, or seeing how they ride = fail.
