Product Information
Full details
The Topeak Toploader Dryshell is designed for endurance cyclists, gravel riders, and commuters who need a secure, weather-resistant storage solution for small essentials. Its primary benefit is the combination of a waterproof, rugged construction with a unique magnetic closure that allows for quick, one-handed access while riding. While the 1L capacity is perfect for tools, snacks, and a large smartphone, potential users should note that the bag's dimensions may restrict steering clearance on bikes with very tight frame geometries.

FAQs
Will this bag fit my 6.7-inch smartphone?
Yes, the bag is designed to accommodate smartphones up to 6.9 inches.
Can I install this on a bike without top tube bosses?
Yes, the bag is fully compatible with the included strap-on mounting system.
Is the bag completely waterproof?
It is highly weather-resistant and designed to protect gear from rain and road spray, though it is not rated for full submersion.
Does the bag rub against my legs while pedaling?
The Dryshell is engineered with a slim profile to minimize contact with your knees and legs during standard pedaling.
How do I clean the internal dividers?
The dividers can be removed and hand-washed in mild soapy water. Let them air dry completely before reinserting.
Troubleshooting
Bag shifts during off-road riding
Tighten the straps around the head tube or check that the mounting bolts are fully torqued to the frame bosses.
Magnetic closure does not seal properly
Ensure no small items are caught in the magnetic flap area and clean the contact points of any road grit or debris.
Pros and Cons

- Fully weatherproof construction keeps electronics and essentials dry
- Magnetic closure is significantly faster than traditional zippers
- Dual mounting options (bolt-on or straps) ensure a stable, tight fit
- Internal dividers keep gear organized and prevent noise
- Sleek profile avoids leg rub while pedaling
Cons
- 1L capacity is limited to small essentials only
- Not suitable for very large bulky items
- May conflict with front-mounted lights or computers on some stems
Setup, Compatibility & Care
To install the bag, first choose your preferred method. For bolt-on setups, align the bag's base mounting slots with your frame's top tube bosses and secure using the provided bolts. For strap-on setups, loop the high-quality nylon straps around your head tube and top tube, pulling them snug to prevent side-to-side movement.
To maintain the bag, simply wipe down the exterior with a damp cloth after muddy rides. Avoid using harsh chemical cleaners, as they may degrade the weather-resistant coating. If the interior becomes dirty, the dividers can be removed for easy spot cleaning. Always ensure the magnetic closure is fully aligned after closing to maintain the waterproof seal.
