Which axle sizes should you pick for your Tourmalet?

For the Tourmalet, selecting the correct axle mounting is the final step in ensuring your bike is held perfectly rigid within its aluminium shell. The mounting system is designed to be straightforward and robust, whether you are packing a classic rim-brake frame or a modern disc-brake machine.

For the front axle, the choice is usually between a standard quick-release (QR) or a 12 x 100 mm thru-axle (though we also offer 12 x 110 mm, 15 x 100 mm and track options). For the rear axle, you will need to match the width of your frame's dropouts: typically standard QR for most rim-brake bikes or 12 x 142 mm for most disc-brake road and gravel bikes (though 12 x 148 mm and track are available). Confirming these measurements before you order ensures that the internal mounting hardware matches your bike’s geometry exactly, providing the most secure fit for your journey.
