This dropout is specifically for the G1 12x142mm Syntace system on Intense's Carbine 275. If you're converting your 26" Carbine to 27.5", you will need the left and right side dropouts, as well as the 27.5" brake adapter
. It is compatible with any 12x142mm hub EXCEPT for Shimano. Currently Intense does not make a Shimano-compatible 12x142mm 27.5" dropout.
