|Front derailleur capacity for triple||bcm119|
May 2, 2003 11:09 AM
|I'm building up a bike I'll use for loaded touring in mountainous terrain. I have a 24-tooth small chainring on an old RX-100 triple crank (standard Shimano road bolt diameter of 130mm). My question is, what is the largest ring I can use for the big ring- a 46 or 48? Shimano claims the front derailleur (also RX-100) can handle a 22 tooth difference between the smallest and largest ring. But 46 tooth rings in a 130mm bolt pattern are tough to find. Can I use a 48?|

|I have heard of a 26/52 being used...that's 26 teeth.Specs are uaually conservative.|

|I use a standard, modern Ultegra triple F. derailer with a 24/36/50 ring combo (110/74BCD) and Campy Ergo shifters.
26 tooth spread. No problems.
