Having a very rigid bike, I used to avoid cobblestones roads. Since I ride with BAM City I ride more comfortably and with full control.
I also have the BAM Grips that provide me an excellent grip.
The handlebar is really well thought, it's a real shock absorber from roads imperfections. Flexible when you need it to, it remains very responsive and lets me be one with my bike.
Excellent product, I recommend!
