The all-new lightweight GT clamps feature our 6mm bolts for ultimate grip on all bar sizes and types. 
Weighing a mere 48 grams, these are our lightest ever clamp. Compatible with aluminium, titanium and chromoly bars.
The clamp comes with a shim, making it compatible with all bar sizes. 
*Note, all bars using a clamp must have a slit cut, the length of which should sit between the height of the top bolt and the top of the clamp.
