So pictured below is the crappiest brand of Mama Chari ever to leave a factory in China - Switch , if someone does offer you one of these for free ride it to the nearest high cliff and toss it as far as you can , certainly do not under any circumstances pay money for one as you are better off walking !
The first time I saw the Switch Zee tube I was dumbfounded to say the least, over the years of fixing bicycles I have fixed plenty of punctures and re fitted new tubes but the first time I worked on a Switch Mama Chari, I could not believe what I was seeing. The tube that was fitted in today's case was 27 x 1 - 3/8 which is in fact the correct size for the rim and tyre. The zee tube was marked Panaracer - made in Japan but it was considerably longer than the same size tube also from Panaracer that I fitted back into the tyre ?. So are the workers at the Switch factory in China using fake Panaracer tubes , we will most likely never know as I certainly have no intention of trying to locate their factory if I did it would be from above in a B-52 bomber ! . The tube is a good 150cm longer than needed and because of this the skilled bicycle assembly staff at the Switch factory somewhere in China decided that the best way to fit this extra long tube into the wheel was to fold it back on itself to what I now call the Zee tube. I now present to you Ladies & Gentleman the famous Switch Zee tube !
So as you can assume it does not take long for the new owner of a Switch to get a puncture and have to visit the local bicycle shop. Most Switch owners take the bike to the nearest bicycle store rather than back to the shop where it was purchased and complain , if they did the stores that sell these pieces of junk would be doing a lot of free repairs as it is certainly not the customers fault. If you are in Japan and would like to easily win a bet , download this photo and go to to your nearest Switch dealer and make a bet with the bicycle sales staff that any Switch banded bicycle they pick will have a zee tube like the one pictured above . I have seen 30 Switch banded bicycles all with zee tubes so I am sure it would be a safe bet to make !
