This is the detangler (gyro) I have on my bike. It works fine. However, SST Oryg makes several different sets of these that are dependent upon the length of the upper cable you need (which is basically how tall your handlebars are), so you need to know that measurement before you order. There are the Flatland, Vert, Poser, Hardcore, and Shortcut lengths. You do not want a cable that is either too long or too short, so first contact the bike shop that sells these through Amazon so they can tell you how that is measured. Or find the information on a website (I couldn't or I would have given it here, but I am sure it is somewhere). Then order the set you need,so you the don't have to get the right upper cable later at further cost.

Anyway, the measurement you need is between the end of your brake lever (where the cable enters) to the rotor on the detangler (which is pretty much the same as measuring to the bottom of the handlebar stem on the typical setup). This is measured in a straight line between the two points (not in a curve like the cable will actually be).

If the measurement is:

180-205mm you need the Hardcore
190-240mm you need the Pro Flatland (some sources claim 210-240mm)
240-280mm you need the Pro Vert
280-320mm you need the Poser
less than 180mm you need the Shortcut

If you are measuring in inches, multiply inches by 25.4 and this will give you millimeters. For example, if the measurement you come up with is 9", you multiply that by 25.4 and you get 228mm, so you would need the Pro Flatland cable. This is actually what the majority of stock 20" and 24" BMX-style bikes would use. So if you are just guessing and don't have a clue, buy the set with the Pro Flatland cable and you will probably get the right stuff you need for your bike. In fact, both my 24" bike and my son's 20" bike can use the Pro Flatland cable. But be more careful with 24" bikes because they tend to have shorter handlebars, so even some stock bikes might need a shorter cable (like the Hardcore).

Also, you have to remember to get the set for the correct steertube diameter, which is either 1" or 1-1/8". Most name-brand bikes will be 1-1/8", but you have to know for sure!

Repaired an used bike for a friend that needed parts. Searched the internet and found all that I needed and was able to have the bike up and running again for the youngster!
