Rims Design is All About the Details
Technical specifications, features, and maintenance rundown for your ride.
Eyelets
We use eyelets on our box section rims to give extra strength to a normally thin portion of the rim extrusion. Currently, the only rim this applies to is the Atlas.
Aero section rims do not require eyelets for strength, since we use extra aluminium through the spoke bed area of the rim. We drill all rims to allow for smooth spoke adjustment, whether they have eyelets or not.
”Always place a drop of lubricant between the rim and spoke nipple when building or making an adjustment.“
Joining Techniques
We use a unique sleeve joining process to create our rims. We use a joiner extrusion that fits perfectly inside the internal cavity of the rim. It is chemically welded in place once the rim is aligned, perfectly round, and flat.
This creates a very reliable rim while maintaining the strength properties of the aluminum at the join, unlike arc or resistance weld joining techniques which can lead to weak or brittle join sections.
Recommended Spoke Tension
We recommend building to spoke tension between 110 kgf and 130 kgf. Each rim may behave differently; the mark of an excellent wheel builder is the ability to find the highest tension a rim will allow while maintaining its radial and lateral true.
Drilling Angles
Spoke holes are drilled at an exit angle of around 4 degrees, and alternate from left to right flange bias at every other hole.
Machined Sidewalls
On painted or anodized rims designed for rim brakes, we offer machined sidewalls (MSW) for superior braking performance. We remove the smallest amount of material possible to achieve a perfectly flat, raw aluminum braking surface.
It is unnecessary to machine silver or polished rims. We leave the sidewalls non-machined even if they are to be used with rim brakes. Those finishes provide great braking performance and do not blemish with wear. The material soared by not machining these rims leads to a longer service life of the rim sidewall.
Tubeless Design
Our tubeless ready rims feature enhanced web geometry for tubeless tire setup. They have tight tolerances in the bead area of the rim. Velotape is required for proper tire fit with or without tubes.
”Any rims that are not listed as tubeless ready must be used with tubes.“
