hey guys.

i probably want to lace my powertap with corima aero rims.

do you have the erd of these rims? how many mm should i add for the up-side-down-nipple?

otherwise: which spoke length (cx ray) do i need for the powertap sl carbon with 32 spokes (2 or 3 cross?) and radial on the front with 20 spokes on a american classic micro58?

thank you very much!!

Hi,

I did the same but with Winium rims. I ordered the rims first (they arrived in 3 days after ordering). It's best to measure the ERD yourself to be safe. To calculate the spoke lengths you could you use spocalc.

Hi Bergziege.

The ERD is 552,9 mm to be 110% accurate. I have got the information from Corima.
In the 2007 Corima brochure it says 553 mm.
You also have to add 4 or 5 mm to the calculated spoke length for the nipple since it is inside the rim.
I'm buildeng the a pair my self. PowerTap 2.4, Corima Aero HP Clincher Rim and Sapim CX-Ray.
Good luck with your build.

Ciao Ebsilon

I am not sure that's correct unless the aero rim is very different from the Winium. The "ERD" as corima lists is the inner diameter of the rim. For the Winium this is listed as 597 which is correct. However, the real ERD as I measured and built with (so did divve) was 618.

Hi strobbekoen

From Corima:

Hello,


The ERD for a 700c clincher Aero is 552.9mm. This is with the seat of the nipple. You have to add about 4/5mm for the spoke/nipple. I can ask to a technician if you know the hub size.

Best regards

The length of 618 is that the spoke length incl. the the extra length for the nipple.

This is what Corima replied to me with regards to the ERD:

Dear Sir,

The ERD is 588 mm (clincher version) and 597 mm (tubular)


And it was wrong.

edit: it was the same person as in your email.

Since corima ships fast, I would really advise to buy the rims and measure first.

Divve had the same problems with his build.. Did you calculate and buy the spokes based on that ERD ?

I hope I am wrong in your case of the Aero rim.. but for the Winium the listed ERD as in the table you showed is definitely not the ERD as is used by spoke calculators .

I have had the rims for some weeks, but I did not meassure them, and now they are sent away to be build. I sure do hope that the builder do check up on the meassures, because I did provide him with the letter from Corima :(

Hi Ebsilon :D

I will tell the builder (sub 10 in the forum) that he has to check it before building.

But i am sure that it will run like never before.

just measure the rim....

If your rim is not listed you will need to measure it. Take two spokes cut down to 250mm (cut off the elbow side). Glue on a nipple so that the top of the spoke is flush with the bottom of the slot in the nipple.

Place in opposite holes in the rim and hold taut (do not apply so much force that the rim deflects). Measure between the ends and add 500mm. Average several diameters.
