A twist shift gear system is a type of gear shifting mechanism commonly found on bicycles. It consists of a grip or handlebar-mounted shifter that allows the rider to change gears by twisting the grip or handlebar. This action moves the internal mechanism of the derailleur, causing the chain to move onto a different sprocket, thus changing the gear ratio. Twist shift gear systems are popular for their ease of use and intuitive operation, making them a popular choice for casual riders and commuters. **

Additionally, the way the T-shirt is sewn together can also contribute to twisting, especially if the seams are not aligned properly. **
