are available and are interchangeable.
The freehub has 4 independently spring loaded pawls and a 36T ratchet ring. It is advisable to re-grease the freehub mechanism with good grease like Rock n Roll Super Web to keep the hub quiet and to stop water ingress weakening the spring.
They are a large flange design because large flange hub reduces the braking loads on the spokes compared to small flange designs. The front hub has 2x NTN 6902 LLB bearings and the rear hub has 2x NTN 6902 LLB. The freehub body has 1x NTN 6902 LLB and 1x NTN 6802 LLB for shimano and 1x 2x 6803 bearing for Campagnolo, XDR and N3W freehubs . All spares are available.
The rim is 430g in weight and is 19mm wide internally 24mm external width. It is 20mm deep and is tubeless ready (tubeless rim tape is installed on every wheelset). The rim is an offset for the front and rear design which means improved spoke tension balance. This one trick to extend spoke life.
The spoke and nipples are the last trick. Black Pillar TB2018 triple butted 2.0/1.8/2.2mm (at the elbow where it matters) give long service life. The elbow being 2.2mm in diameter has 21% more cross-sectional area than a Sapim race or DT Swiss Competition spokes. What is not to like about that? The nipples used are black Sapim alloy nipples. Sapim nipples are reliable, nipples failures simply don't happen on my wheels. It's a warranty if it does.
So, in short, this wheelset uses all the tricks I know to create a stiff reasonably light but robust wheelset that will give you smiles for miles. I deploy all the tricks as tubeless tyres compress tubeless compatible rims (tight fitting standard clinchers do too) and this cause a significant tension drop that must be accounted for when building the wheel. I cannot raise the tension as some tyres cause a bigger drop than others. So tricks to improve tension balance and extend spoke life are a better way of creating a reliable wheel for all riders regardless of the tyres they choose to fit.
