DT Swiss Conversion Kit for 180/240s/350 142/148/157 x12 SRAM XD

End caps to convert the DT Swiss 180 Classic MTB CL db and 240s/350 straightpull/Classic MTB CL/IS db rear hubs with SRAM XD freehub 

Weight: 18g (to 12x142/157/197mm Thru Axle

In Picture 2 the 142 and 148 hub dimensions, as you can see the hub internal width is different from hubs so you must workout what hub you have then decide the end caps to make it fit the hub width you desire 

Picture 3 shows This is the 157mm hub and can see the extra internal width. So, the different end caps with DT make a 6[mm] difference. Therefore a 142[mm] hub can become a 148[mm] and a 150[mm] can be a 157[mm], even though it is only 156[mm] the actual difference is in the small offset amounts allowable.

Update: As we've measured up ourselves converting 150 to 157 it comes in at the 157mm total length with these end caps
