TCUs are great for anywhere that weight is a critical factor, their narrow head width allows them to fit so many placements that other cams won't, like shallow seams, pockets and pin scars.
By going direct to the axle (D.A.T.) Metolius have made the world’s best selling mini cam even lighter and more versatile. This new technology makes TCU’s the lightest units in the world, opens up a myriad of placement options and makes placement easier. The design is focused on holding power, with an optimized cam angle for more outward force and wider cam faces for more grip.
