Topeak MTX DXP

The Topeak MTX DXP is specifically designed for the Topeak MTX QuickTrack rack system. While it may sit on other racks, it will not lock securely into place without the QuickTrack rail system.

The bag offers a total capacity of 22.6 liters. The main compartment is spacious enough for a lunch and extra layers, while the side panniers deploy to hold groceries or additional gear, effectively doubling your storage space when fully expanded.

Yes, the main compartment is insulated to help maintain temperature. It works best for short to medium commutes when paired with a small ice pack, though it is not a replacement for a dedicated hard-sided cooler.

The bag is constructed from 600 Denier Polyester, which is water-resistant and handles light rain well. However, it is not fully submersible or waterproof in heavy, prolonged downpours, so you may want a rain cover for extreme weather.

It is quite convenient. The bag includes a detachable shoulder strap and a sturdy top handle, allowing you to quickly unclip it from the rack and carry it into your office or a store like a standard messenger bag.

Because it uses the MTX QuickTrack mounting system, the bag locks firmly onto the rack. This provides a very stable, rattle-free ride, even when you are navigating bumpy city streets or gravel paths.
