This new addition to the Crombie family is specifically designed to work with the new external splined lock nuts found on new Shimano MTB transmissions equipped with a 9-tooth final sprocket. 

This new Crombie tool features one side for the new nine-tooth lock ring, whilst retaining the traditional 'S Group' Thru Axle tool on the other side. This makes it an ideal choice for modern MTB and gravel specialist shops or garages. 

Made in Bend, Oregon.
