What are the advantages and disadvantages of a longer chainstay on a DH bike? For example : The IH Sundays have a 17.25" chainstay. The Commencal Supreme DH has a 17.79" CS The Cannondale Gracia DH has an 18" CS. There's a big difference between these 3 top DH bikes chain stays, but why? I personally noticed that my 17.8 CS DH bike is more stable at high speeds, but it turns slower than bikes with a shorter CS. I also have to use a lot more 'body English' to get the bike into corners and through rock gardens. Any info on CS length is welcome.
