Today I was going downhill a little on a narrow street when I notice a dog-leash and had to make a relatively quick full stop. Even though I was sitting with all my weight, the front brake definitely lifted the rear wheel.
I tried the same on the flat later on. I just pulled the level on full speed and the rear wheel came off the ground again.
When I go that fast and do a skid, I start fishtailing with or without rear-break.
Would a rear-break still help me stop faster?
