FAQ

What is the difference between the Grande and the Standard Mattone?

The Grande is 0.74L, nearly twice the 0.41L of the Standard. Same Boa Closure System and build quality. If you ride far enough that you need multiple tubes or want CO2, levers, and a multitool all in one bag, the Grande is the right choice.

Will the Mattone Grande fit my aero seatpost?

Yes. The attachment system accommodates standard round and aero-profiled seatpost and saddle rail combinations. The Boa strap cinches securely around both types without adapters.

How does the Boa Closure actually work?

Turn the dial to ratchet the strap tight, and the bag locks in place with significantly more force than a Velcro closure. To open, lift the dial and the strap releases instantly. One-handed operation even with gloves on.

Best For

Cyclists doing long road rides, gravel events, or bikepacking routes where carrying two or three tubes is smart preparation. Also the right choice for mountain bikers who need extra tube volume without resorting to a full frame bag.
