Hi guys, this thread has been one of the most interesting I have read. I come from BF and I really got interested. I was thinking about making a 20mm/38mm wheelset with the suggested Soul Prodigy Hubs and probably DT Swiss aerolite spokes. Unfortunately many of the rims don't come with a minimum order of one. I was looking at this 215g rim: http://www.alibaba.com/product-gs/33933 ... bular.html and this 38mm 280 (or 330g?) rim: http://www.alibaba.com/product-gs/38040 ... e_rim.html

Using the middle ground for the 38mm rim, it would be
20mm 38mm hub spokes nipples
215 + 305 + 288 + 158 + 11 = 977g

I was thinking a 16/20 hole pattern because I weight 135 now, so I'm not too worried about stiffness.

Anyone else do something similar?

Thanks for the thread, -- Chad

So I've done a few races on my 20 mm carbon tubulars w/ Soul prodigy V3 hubs. Total wheelset was about 1000 grams. My scott addict SL w/ pedals, bottle cages, and power tap wired setup (no hub, just wire sensor and computer) weighed 14.06 lbs. These wheels have vittoria 320 tpi 23 mm tires on them. My thoughts are that these wheels are great. Plenty stiff, good braking, roll true. For $600 this is an amazing wheelset. They just float up the hills. Anyway, I have another set coming in soon, but this time I got the 50 mm carbon tubulars. Also bought the bikehubstore.com hubs for $100. They seem almost the same as the soul prodigy V3 for $150 less! Anyway, I'm excited to get these new wheels b/c I want to use them for Tour of the Gila. Maybe the first day I'll use the 20 mm tubies, but for the second day and the crit I'll use the 50 mm tubies. Great wheels for a great price. I'll post a picture of the wheels later. They look the same as Ted's who has posted extensively on this subject.

@ Chiva, as in Gila Wilderness? I was there backpacking in December. I saw the road going to and from the Cliff Dwellings marked up as if for a race. That would be an awesome road for a race!!

Hi Dan 520. I'll be racing in the Masters 40 category. Its gonna really hurt. I'll post a picture of my bike w/ the carbon wheels tonight. That way you can recognize me by my bike. Tour of the Gila should be tough as always. My team is really looking forward to it. :D

I've got a pair of the Planet X 20mm carbon tubular rims for sale in the For Sale section. Both rims are 20 hole. $225.00 plus shipping.

I've no experience building wheels, but work in a bike shop where my colleague will help me build up a set of 20mm Planet X Carbon Tubular rims (20/24) on BikeHubStore's UltraLight hubs.

I'm trying to source the parts myself so that all he has to do it build them, so I need to know the spoke lengths and ideally the best lacing pattern?

I put the details into a spoke length calculator (http://www.wheelpro.co.uk/spokecalc/) and got the following results.
Front spokes:

Rear spokes:

So what option will I go for based on that spoke length calculation, the shaded grey area shows radial if possible with the hub (is it possible with the hubs I am going to use), white is the preferred pattern, blue will work, and red is not recommended.

What have ye used and found ideal as I need to order spokes. And another question is Sapim CX ray or DT Aerolite?

Thanks in advance

Yes you can lace those hubs radially. Spoke pattern is up to you and your preferred characteristics. I've built a set 2x ND and Radial DS. Terrific so far, but 2x/2x, 2x/1x both would have worked. Lots of people have done 2x DS, Radial ND.

Both spokes build nice wheels. Can't go wrong there.

Thanks for that. Is there anywhere that I could find out the caracteristics of each lacing pattern. If I told you I was 59kg, 171cm (5'7") and fancy this wheelset as a climbing wheelset for hill climbs and hilly races what would you recommend. I am not a specific sprinter but can do a fairly decent sprint all the same if that would have any bearing on my choice. Again, I really appreciate your help.

EDIT: Also considering this is a budget lightweight wheelset, with the tims only costing $280, the hubs $110, are Sapim CX ray or DT Aerolite spokes overkill for this build? Any other relatively light spokes that would be more cost effective for my needs? Thanks

A central database would be lovely, but I haven't seen one... There is lots of info somewhere within this gargantuan thread. In principle radial spokes will resist lateral forces, and tangential spokes will handle torque from pedal and braking forces.

2x Non drive, 1x drive side (or radial) I found to work very well with the BHS hubs. 2x/2x resulted in very low ND spoke tension. Radial drive spokes allowed a significantly better balance between DS/ND.

For that build I used Sapim Laser spokes. 30% the cost of a CX-ray. You could even order them from Bikehubstore.

Random question, where are people picking up the 20mm carbon tubular rims from? I've had a look on hong fu and the smallest they do is 38mm. Any guidance much appreciated.
