Hello, Firstly I havent used Spdsl pedals untill recently as I was using my easy to walk in spd's but as the desire for more power came out went the comfortable and in came the performance orientated- as such I bought some spdsl ultegra sl pedals and MOst carbon Panther series shoes but they creak!! Is that something that will go with time? I also havent decided if its the upper or the Carbon sole? The carbon doesnt seem to be able to flex in my hands, has anyone else had this prob? Cheers
