Topeak MidLoader

The MidLoader is designed to fit most standard bicycle frames, but it is best to measure the space inside your front triangle before purchasing. Because it mounts using adjustable hook-and-loop straps, it offers flexibility, but it may not fit very small frames or frames with unique geometry.

No, the bag is made from water-repellent materials, which will protect your gear from light rain and road spray. However, it is not fully waterproof, so we recommend using dry bags for sensitive electronics or clothing if you are riding in heavy, sustained rain.

It depends on your frame size and bottle cage placement. On many bikes, the MidLoader will occupy the space typically used for water bottles, so you may need to relocate your bottles to the seat tube or use a different mounting solution if you need to carry hydration.

With a 4.5-liter capacity, the MidLoader is ideal for heavier, denser items like tools, spare tubes, a multi-tool, or a lightweight rain jacket. It is designed to keep weight centered, so it is perfect for items you don't need to access constantly while riding.

The bag mounts securely with hook-and-loop straps, but any frame bag can cause minor rubbing over time due to vibration. We recommend applying a protective frame tape or clear adhesive film to your bike's tubes where the straps and bag make contact to keep your paint finish pristine.
