Re: Dual rear brake calipers

Yea, also you must be very carefull not the lock the wheel up when you downshift or that your spring setup is correct becaus if the wheel stops moving then the force of the rear caliper is no longer tranferred to the swingarm but it then works as a normal caliper.

I wonder how Jan Greven managed to ride this in a race

Re: Dual rear brake calipers

If the rear wheel locks on a downshift (if you dont have a slipper clutch) you can modulate that back out by using the clutch.

If the rear wheel locks due to a linked brake system, you have to let out of BOTH brakes to return traction to the rear brake.

That instead of the backend of the bike that raises (like in a normale situation) you will also force the swingarm downwards.
Application of the rear brake has no effect on this.

Having free sag in the rear shock does. Once the swing arm has fully extended under hard front breaking, there is nothing you can do to force it towards the ground other than letting off the front brake a little or trying to roll your hips backwards to transfer for weight to the rear of the bike.

Re: Dual rear brake calipers

notice two of those three shots they do appear to be using (or were using shortly before photo was taken) the rear brake though .

The rear has benefits. Almost ZERO of those benefits are in slowing the bike down. They are all in chassis dynamics. But it can be used.

With that said, having it linked makes controlling those chassis dynamics nearly impossible.
