Asymetyric rims, best end?

[wkkie]

I have to get a new rim for a wheel build. I've already got 1 rim which is standard drilling.

I'm thinking of going asymetric for the other rim, and was wondering which end it would be most benefitical at? Front or rear? Reasons?

The build will be non boost, 100mm x 15mm front and 142 x 12mm rear.

Usually the rear. The front doesn't see as much force put through it. But this is dependant on the rim. If its a choice between standard drilling and asymmetric with similar wrights from the same manufacturer then no problem. If its a toss up between a Dt ex471 and a WTB Asym i29 I would take the Dt.

Yes to rear. Tension imbalance side to side is largest on rear because of the dish needed by the cassette.

asymmetrical for the rear.

bracing angles are helped by asymmetrical rims on the rear

Rear. Because the DS/NDS tension difference is usually greater.

+1 to all the above.
