Oct 15, 2001 9:20 AM | | The only potential problem I can see...and it might not be a problem at all...is running an XTR front derailleur with a compact crankset. Shimano claims that the XTR front chnger is optimized for the standard sized XTR chainrings (24/34/46 tooth). If you haven't already bought the stuff...I would go with an XT front changer. If you've already got it all...bolt it on and see how it works.
Good luck,

Q: What's the deal with different actuation ratios?
A: Well, SRAM's ESP design uses a 1:1 ratio. This means that for each millimeter of cable moved in the shifter, an equal millimeter will be moved in the derailleur. This allows a greater acceptance of off-road conditions (dirt, water, sand, etc.) and also gives SRAM a unique shifting technology. Conversely, Shimano uses a 1:2 ratio for it's shifting systems. This means that for every one millimeter of movement in the cable there will be two millimeters of corresponding movement in the rear derailleur. The ratios are not the same; therefore, you cannot use an ESP shifter and a Shimano derailleur, or vice versa.
