With thru axles becoming more and more common the original Crombie tool was due for a makeover. We took the piloting pin and plus sized it to work with the 12mm thru axle fitment that is actually standardized. We make this version as a dual sided tool with two S Group ends, one for thru axle wheels and the other for regular hubs. The regular side has a hole deep enough to hide a skewer nut, it's really the best of both worlds. The STANDARD version comes with a solid handle while the SUPER LIGHT has a hollow handle to save weight for the traveling mechanic. SL handles are plenty durable for lockrings that are torqued close to the 40 NM spec. If you commonly come across over torque lockrings get the standard handle. Note, this version of the Crombie tool is not compatible with any Campagnolo wheels. Made in Bend Oregon.
