I can live with the 40 gram increase in weight in exchange hopefully for a bit more durability and the ability to lace up a new rim myself if something happens.

Recommend switching to BRASS nipples especially for tandem use. Alloy can gall on non-eyeleted rims so you'd need to use washers to prevent that. Also they can strip, corrode and crack - tandems put a lot more stress into wheels than singles where alloys are ok. Go for durability and no headaches with brass.

Sapim Race or DT Comp (similar) front & rear would be fine unless you plan to do loaded touring or Roubaix.

Updated the order - subsituted the Sapim Race for the Sapim Strong on the rear and went with the brass nipples on both wheels. I didn't think of the corrosion issue - always have built rims with eyelets and in talking with the builders they agreed that it could be an issue down the road. I was on the fence with the Strong spokes to begin with - and the trade-off with the brass nipples brought the weight down a bit to be almost equal to the original build. Not that I'm a weight weenie - but wanted to keep them in that range.

The customer service from prowheelbuilder.com has been outstanding. They have responded incredibly quickly to all my inquiries and have made the changes I've requested immediately.

I've literally had old alloy nipples crumble in my hands. +1 on the switch to brass, its well worth the weight penalty.

Wheels arrived yesterday. Nicely packaged and all the info on the build included, spoke tension etc. Very happy with the purchase. Put them on last night and we'll take the tandem out tonight for our evening ride.

Nice.

I don't recall what you were previously riding but be sure to adjust tire pressure for the new rim width/volume. We dropped ~10psi when we switched to these 23mm wide rims from 18.5mm rims.

I'll have to reweigh our set with the new CLD 135mm hub, maybe do that this winter. I think the current build is something like 1750gm + skewers (Salsa) and rim tape (Zipp).

We are on 28mm GP 4000's. Ran at 120psi on the Rolfs. Currently at 110 psi for it's maiden voyage.

I was a bit concerned about the quality of the Kinlins - but they appear to be very nicely made. Time will tell.
