Sirius Rx Frame

Very stylish frame but I have to push glasses back all the time when I'm riding my bicycle because they are sliding forward . I tried to play with the bridge position and tension but it didn't help. What would be really helpful is if I could bend the arm's ends around ears to keep glasses steady. The frame is light and stylish and perfect for casual use but it's intented to be used for active sports and unfortunately that part doesn't work well. Kind of disappointed, considering the premium cost I paid for it.
