Maybe a kinlin xr31?

Or an HED belgium rim? Their deeper rims are alloy but with carbon fairings.

I will go with the DT Swiss RR-511. Front 20 spokes, rear 24 spokes on my DT Swiss 240 straightpull hubs.Wich spokes do you recomand. I want the build as cheap as I can but not to heavy.

Do the spokes have to be dtswiss?

Are you big and heavy? Doing lots of sprinting? Would you say you're above average when it comes to power output?

My weight is 83kg and do a lot of clubrides with at the end it always comes down to a sprint. My nominal power output at rides is 260W

Dt spokes?

With that spoke count, weight and use, better go with a 6gr spoke. Dt don't have any bladed 5gr spokes, and 4gr is too thin.

If you do Sapim you could do cx-sprint.

If you do pillar you could do 1423 which are you best bang for the buck. 6gr and builds a bit stiffer wheel.

I would like to use DT spokes.

If that's not an option, are there dealers in europe for the Pillar 1423 spokes.

The Sapim ones are pricy, 140 euro at 44 spokes.

Cx-rays are in the 4gr category. Ok for deeper rims, ideally carbon.

None of the DT's I can use like the aero comp?

DT Aero Comp is a very good choice (based on weight/dimensions) for your wheelbuild.

Are they cheaper than Sapim?

Sapim cx sprint or cx force. Man this is not a hard choice to make.

If you agonise over spoke choice dont try to spec the wheels yourself.

What parts do you have already? What you are describing is the DT Swiss PR1600 wheelset off the shelf. Unless you've got the rims and hubs on the shelf, that'd be the way to go. If disc, get the ER version. https://www.merlincycles.com/en-us/dt-s ... 08395.html

75gr extra isn't going to make a difference in a sprint, ever. You're better off getting a wider rim of the same depth and a tire that fits that rim well.

Good point jfranci3. Does dt offer a discount on wheelsets compared to ordering parts, or are they usually more expensive?

Another affordable 6gr spoke is cnspoke aero474. Taiwanese spokes like cnspoke/pillar are usually found on aliexpress (for common models) or taiwanese sellers on ebay for obscure models.

I have a spoke tension question for you wheelbuilding experts. In the attached chart it shows measured spoke deflection as measured by a tensiometer for a given tension. Spoke #20 is the lighter weight spoke and #23 is the heavier spoke. It seems that for a given tension the lighter weight spoke will actually deflect less in a tensiometer? I recall reading comments here that a light spoke will feel very tight by the hand. This seems counterintuitive but perhaps the thinner spoke is like a string that needs to be pulled very tightly to generate the needed tension. Thanks.
