28 hole hubs - cant decide on what rim to buy!

just bought some hubs for a 28 spoke count and I cant decide on which set of rims to buy.

I was thinking of some mavic open pros but they're a little out of my price range; so after that I thought mavic open sport but they only make a 32

so help!

I've heard these need to be trued more frequently than others, is that true?
I'm also looking for a more low-profile rim; something far from some deep v's

thanks for the info on the rim though, I'll check it out

I've build wheels with Open Pros, Open Sports, and Velocity Aeros. Aero has a non-machined braking surfaces, but I didn't have any problem maintaining +/-0.001" tolerances axially and radially. The spoke holes as seen from the rim-tape side are drilled at an angle and offset to the left and right. Left holes go to the right side of the hub, and right holes go to the left side of the hub.

The Aero rims is much easier to build and quite a bit stronger than the Open Pro or Open Sport. Only minor complaint is the non-welded joint seam. I simply use a small file to blend the joint smooth (remove less than 0.001" of material from the rim). This is my favorite high strength/low cost rim. Add 1mm if you use the DT spoke cal program. I lace with DT Champion 2.0 mm straight gauge.

Aerohead is similar to Aero...a little lighter, so you would loose a bit of strength.

Since you have a low spoke count, the best rim for the $ is probably the Deep V. A low-profile rim tend to be less robust with 28-hole hub.

if you can't decide on a rim, just sell the hubs to me and be done with it.

After riding 32 spoke wheelsets for many years, I decided last year to finally build myself and try out my first 28 hole wheelset this summer. I used 28H Stronglight Delta hubs with Wolber Profil 20 rims and DT SS Aerolite oval spokes. I made a concious decision to use the Wolber Profil 20s on this build as the rims are much beefier/stiffer than previous 32 hole rims I had built up and rode (Mavic GEL280s and GL330s). The Stronglight hubs are also beefier than what i had used previously (Ofmega CX, Malliard/Spidel 700), and have very similar crossectional shapes to the Mavic 500 series hubs. The 28 spoke wheelset combination I put together seems to be working very well so far maintaining their trueness, plus the wheels feel very stiff laterally. So, I agreee that going with aero rims that are usually beefier, with more crossectional material instead of lower profile box rims will most likely be more reliable/stronger with the low count spokes. Just make sure you tensoin and true the wheel very well and do all the neccessary pre-stressing so they wheels stay true longer for you.
Please tell us what you finaly decide on and show us the final build result!

haha t-mar. I'm sorry, but the hubs are somewhat special to me. They're a set of gipiemme crono special NOS hubs for my bianchi build. I don't know why, but I HAD to have them on my bicycle...( i wanted that vintage look, but gipiemme parts)

but IF I DO happen to change my mind, you'll be first on my list to message!

yes, I understand that for many people that would be a problem, but since I have a low weight (125-130) and I like the look of the low-profile rims, I don't think strength of the rim would be THAT much of a difference.

thanks for the info though! it's like I learn something new on the forums everyday haha

don't worry, I still have a bunch of pictures to post AFTER the build of the whole bicycle. I wanted to keep it unposted till it's done.

I bought a set of mavic cxp 22s ? drilled in 28, haven't built them up yet, I don't like the fact that they are wide (like open pros), Kinda wanted to see if I could find another 28 hole rim thats better (i only really need to build a rear wheel), but its hard to find any clincher rims in 28 hole I find.
