Standard
Classic hole drilling, with a larger 8 mm hole drilled on the outer
circumference of the rim for inserting the nipple and a 4.5 mm hole on the
inner circumference to support a standard nipple. The vast majority of our rims
are built with these standard holes. The wheels can then be trued from both the
inside and the outside.
Without rim bead hole (Tubeless ready)
In this version, only 4.5 mm holes are drilled on the inner circumference to
support a standard nipple. There are no holes on the outer circumference. This
option is ideal because no tubeless tape is needed. The disadvantage becomes
apparent when building or replacing a nipple: the nipples must be inserted into
the rim through the valve hole, which is relatively complicated.
Internal nipple hole
Internal nipples are used mainly on road bikes and when aerodynamics and a clean
appearance are the top priorities. A larger 8 mm hole is drilled on the outer
circumference for inserting the nipple, while a small 2.5 mm hole on the inner
circumference allows only the spoke to pass through to the inside of the rim.
Special internal nipples with a square head are used in this case, and the wheel
can only be trued from the inside of the rim.
