SRAM Force Rear Mech review
In contrast to some other parts of the groupset, there haven’t been that many changes between the 2009 Force rear mech and 2010’s.
The outer pulley cage is now made from unidirectional carbon ﬁbre, which trims a few grams compared with last year’s – while a magnesium inner parallelogram link also helps to keep things svelte.
It weighs about 30g more than SRAM’s top-end Red rear mech, but is still lighter than that from Shimano’s second string Ultegra groupset.
And whereas we had a few shifting hiccups with the Red rear mech when we tested it, the Force mech behaved very well; even under race and climbing conditions we were unable to get it to mis-shift.
