Re: {Classic Rendezvous} Campag HF Hubs vs. Spoke X-ings ?

(Example: Production Builders:LeJeune)



You may think it's overstated, but that's your opinion. In fact, I'm looking at a set of LF (LF= Large Flange, SF= Small flange) 36h, 4x wheels laced to 700c Fiamme red label sprint tubular rims. Guess what? The spokes overlap adjacent spoke heads. I haven't seen your complete wheel, but please check again.

FWIW, any time a spoke touches/crosses an adjacent spoke head, you are asking for trouble, IMO. Not only does it introduce an unnecessary stress point on the spoke, but also on the hub flange, not to mention a source of noise, clicking, etc.

This topic is a no-brainer to me, so I'll leave it as my opinion and live with it.

Take care, John
