The lightweight Max Speed Ball with the matching Kewlus Adapter will allow you to quickly switch to a faster cobra bag ball in mid session. This ball is made from a lightweight synthetic fibre material (the SF in the name stands for Synthetic Fibre) that is also strong and springy, making your cobra bag that little bit faster and rebound further. It is easy to install the included Kewlus Cobra Bag Adapter due to the ball's zip opening. The velcro strap at the bottom covers the zip puller and gives it a very neat look.

IMPORTANT: please ensure the ball is inflated properly when training. Punching a poorly inflated ball can cause damage to the adapter.

CAUTION: Please do not use a compressor to inflate the ball as it is likely to burst.

Max Speed SF Ball & Adapter Combo

Great bag

Great service and fun bag to use.

Good products!

I recommend


Oh my. I assumed the speed increase would be fairly noticeable, but it’s much more than that. This cobra bag was already awesome as a whole, but now it’s elite with this additional speed. And I haven’t even combined it with the red bar yet…

Called Max Speed for a Reason

Like I said In the title, it’s called max speed for a reason, the adapters easy to use, the balls super soft so knuckles feel great and also super fast , way faster then other bags you can get at the same price, best bag out there especially for the price
