2010 SRAM XX Low Clamp Front Derailleur
The SRAM XX Low Clamp Front Derailleur is not a triple chainring front derailleur. It's not a compact double front derailleur. It is its own thing. And while it's designed to handle up to a 15-tooth differential between the big and little rings, its cage is shorter and narrower than a ...read more
2010 SRAM XX High Clamp Front Derailleur
The shifting feel of SRAM XX is accurately described as supreme. The SRAM XX High Clamp Front Derailleur is a notable part of the whole package. It's specifically designed to work in harmony with the XX double crank. The XX front derailleur is made to handle up to a 15-tooth differential ...read more
2010 SRAM X-9 High Clamp Front Derailleur
At first glance, the SRAM X-9 High Clamp Front Derailleur looks like the X-Generation with a new finish. It isn’t. The cage looks basically the same, just less metal. There’s more of a difference than that. The X-9 parts are forged, whereas the X-Gen is stamped. As component trainspotters know, ...read more

2010 Shimano XTR Front Derailleur - Top Swing FD-M970
Shimano XTR 970 front derailleurs are a refinement over the 960 series. The logo has been laser-cut through the cage, the finish matches the rest of the 9707 line, and the back of the cage is more minimal. The two features save you 7g over last year’s design. As with last year, the seat tube ...read more
2010 Shimano XTR Front Derailleur - Traditional FD-M971
After all these years, it turns out that the front derailleur can still be refined. Besides the wider link that the cage pivots off of for easier shifting, there was metal to be removed and the limit screws to be repositioned for easier access. Many will say “so what, it’s just a front ...read more
2011 Shimano XT Top Swing Front Derailleur FD-M770-10
Shimano chose to remain with a triple crankset with their Dyna-Sys 10-speed XT group. One of the key differences was a move to a tighter chainring spread. The FD-M770-10 Deore XT Front Derailleur is made just for its 24/32/42t configuration. The cage radius and plate shapes will optimize the ...read more
2011 Shimano XT Traditional Front Derailleur FD-M771-10
The anatomization of Shimano's XT Dyna-Sys front derailleurs begins with top swing (low clamp) or traditional (high clamp). The top swing design includes the E-type, and the traditional design includes the new direct mount (not to be confused with E-types foregoing their bottom bracket plates ...read more
2010 Shimano XT Front Derailleur - Top Swing FD-M770
Metal stamping. Looking at the 25th anniversary Shimano Deore XT FD-M770 Front Derailleur, we think of that lowly art. Crudely stamped and cheaply plated parts formed form thick sheets of steel adorn many a Huffy, Columbia, and Free Spirit, but high-end front changers are impressive works. ...read more
2010 Shimano XT Front Derailleur - Traditional FD-M771
Style. We'd all prefer more rather than less. Even if we don't admit it, we'd prefer a part that has something to distinguish itself from others, even if the part isn't particularly important. Shimano addressed this concern with their new Deore XT FD-M771 traditional front derailleur. It has ...read more
