The Topeak Wedge Pack II is a versatile saddle bag whose storage capacity can be increased. You don't need to bring the same things for every ride. When you go for a short ride, you only need some essentials. When you go on long trips, it is nice to be able to bring more items. The Wedge Pack II has been designed to let you adjust the bag's storage capacity; its volume can be increased by 0.3 litres, taking it from 0.95 to 1.25 litres. QuickClick system The Wedge Pack II is easy to remove from your bike thanks to the QuickClick system. This makes the saddle bag very useful for stops en route, allowing you to store a bank card, some cash money or similar items in it. The QuickClick system involves a clamp that is to be screwed onto the saddle rail using an Allen key. Then the saddle bag is attached to this clamp with a simple click system. Another advantage of the QuickClick system is that it is compatible with other Topeak saddle bags featuring this system. This allows you to swap such bags easily. Construction The use of durable materials makes the Wedge Pack II highly reliable. Even the rear light clip is made of a sturdy rubber. As there is a reflective strip all around the bag as well as reflective strips on the zip loops, your visibility in traffic is increased not only from behind, but also from the sides. If it rains, you can use the included rain cover to prevent the bag's contents getting wet. This rain cover is a bright colour to make you highly visible in traffic.
