The Claris FD-R2400 that came with the double Suguino XD2 on my Sam did not have enough throw when I took off the bashguard and added a third ring. My rings were 46-36-26. It was not an adjustment thing. The 2400 was not physically able to move far enough. The FD-R2000 lists the same 43.5 chainline as the 2400. So I would say NO.
I would suggest going to a triple, like a Sora FD-R3030. The chainline thing is interesting. Chainrings are typically 5mm apart. The chainline is the middle of the chainring set, measured in mm from the bike centerline. For road bikes, Shimano spec, a double crankset has one ring at 41 and one ring at 46. For triples, one ring is at 40, one at 45, and one at 50. So the chainline for a double is at 43.5, and the shifter has to be able to bring the chain in to 41 and out to 46. For a triple the chainline is at 45 and it has to bring it in to 40 and out to 50. That's Shimano spec. Rivs Silver cranks are installed with bottom brackets that move the chainline out to 47, probably because of the 135mm rear (MTB) spacing. Now a Shimano road double derailleur would have to be able to move to about 52, plus some for adjustment, to the outside of a triple on a Riv. They're just not designed for that. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
