"New Release" Patented Mechanism Solves 3 Major Stresses of Bicycle Covers. SaDock Launches March 31st

norokka (Arkz Inc., Headquarters: Minato-ku, Tokyo, Representative Director and President: Akihiko Murazumi), which develops rain covers for bicycle child seats, etc., has launched a bicycle cover that solves the three major stresses of bicycle covers: "getting dirty, getting confused, and losing." With a new concept of fixing (docking) the main body to the saddle, "SaDock" minimizes the stress of attachment and storage and prevents clothes from getting dirty. norokka is a brand that fulfills ideas born from real-life experiences with new concepts.

"Three Innovative Smoothnesses" Achieved by a Patented Mechanism

norokka's bicycle cover solves the three major stresses associated with conventional covers – "clothes getting dirty," "getting confused about which side is front," and "losing the storage bag" – thanks to its unique patented mechanism that fixes (docks) the main body to the saddle.

1. When folding: Solves the stress of "clothes getting dirty" With conventional covers, it was difficult to remove and fold them carefully to avoid dirtying clothes. SaDock uses the saddle as a workbench, allowing you to simply fold it inwards and put it in the bag. It eliminates the hassle of careful folding, making preparation stress-free even before a busy departure.

2. When attaching: Solves the stress of "getting confused about front/back" With conventional covers, it was frustrating to have to redo it because the front and back were reversed, or the cover got caught midway. SaDock fixes the bag, ensuring the front and back are correctly set, allowing for quick attachment by simply pulling it out. You can protect your bicycle in an instant, even when it looks like rain.

3. When storing: Solves the stress of "losing the storage bag" With conventional covers, you worried about where to put them when going out and the risk of losing the storage bag. SaDock eliminates such worries because the bag is integrated. You can buckle it and carry it while it's still on the bicycle. You no longer have to worry about where to put the cover.

Recommended by professionals! Shorter hem specification

It is often thought that covering everything is best, but under the supervision of mechanics, we intentionally made the hem shorter.

[Benefits of a shorter hem] - Reduces rust by allowing moisture evaporating from the ground after rain to escape - Prevents the cover from getting dirty as the hem is less likely to touch ground mud or puddles - Allows wind to escape from underneath, reducing the risk of tipping over in strong winds

[Why a shorter hem is okay] - The true purpose of a cover is to protect movable parts (chain/derailleur/brakes, etc.) from rain and dust - Tires and rims are originally designed to get wet in the rain
