These fit many different brands of frames. We probably do not know if they will fit your frame though. So how do you check? If you still have a tensioner bolt from your frame, you can use the thread checker tool in the nuts and bolts section of any hardware store. If you do not have bolt currently, go to your local hardware store and buy a M4-0.7 bolt. They wont have a long enough one to use as a tensioner but you can buy a low quality shorter one to check compatibility with your frame. It will probably cost you under 50 cents. Once you confirm the size is the same, order these bolts.
