THE UNDENIABLE RADNESS OF BRAKING
Of all riding skills, braking probably gets the least attention. But it sure is useful. And, dare I say, it’s HOT!
Here’s a preview from MMBSii. It shows some decent braking technique—and it shows how little space a decent braker needs to slow down.
Equipment: Hayes Stroker Trail brakes with 6-inch rotors, Specialized Eskar Control tires, 2008 Stumpjumper Pro Carbon frame/shock/fork
Surface: Dust over hardpack
Distance to decelerate from 24 mph to 6 mph: about 12 feet
Time to decelerate from 24 mph to 6 mph: about 0.5 second
Ramifications: Learn to brake effectively. Know you can slow down in a tiny space. Let ‘er rip!

Nice demonstration Lee.
I did notice just how far back the front wheel tucks under the front of your bike in photo #2. The axle looks to be in line with the head angle. Perhaps it’s just the photo angle.

Petey! Holy cow, the fork is bending back.
A little extra suspension, eh?

EH!

Let’s see the numbers for the effective head angle/trail!

Roughly, from the graphics program:
Fork angle at rest: 69 degrees
Fork angle under heavy braking: 72 degrees

[...] You can stop plenty fast with Strokers and 6-inch rotors. By my calculations, this represents 1.6G of deceleration. Watch that fork flex! The undeniable radness of braking [...]
