hey guys im looking for some info here. my current race bike is a scott CR1 with full SRAM Red and im using the 1090R chain that comes with it, my problem is that i train alot and race this bike and im stretching chains about every 1000-1300 miles. i do all flat road stuff but im doing intervals and crits and im a sprinter type. im looking for a chain that will be the same weight as my 1090R but will have a little better life. according to campy's website the chorus is 255g at 114 links which is exactly what mine is and i always hear from guys i race with that campy chains last alot longer. so im asking what your millage like, given the type of riding that i do what could i expect.
