What rims do I build with?

Hello all! I'm building my very first set of track wheels and I have a question for all you experienced track riders out there. What rims should I build with? I have a set of NOS early 80's 28 hole record track hubs that I will be using, and I have decided that I want to go the clinchers route. I only weight 130 lbs, and the bike won't see any hard city riding, so I'm not too worried about finding the strongest rim on the block, just something that will hold up. I do need something machined though, at least up front, as I will probably use the wheelset on some pretty hilly country rides where I might (just maybe) run a brake. I've been looking at open pros, aeroheads, and the DT Swiss RR 1.1 so far (all really light!). I'm not crazy about the look or weight of deep aero rims, but if there is some really compelling reason I should consider them, I'm all ears! Any advice you have for me is welcome!

Thanks!
Sam

use anything!, Anything will do with your weight and the use u want to give to the wheels... after all 28 spokes WAS something to be used only in time trials back in the day. Is your choice...

Have fun...

I just used DT Swiss R1.1's to build up my high flange dura ace hubs and they are light and stiff. I'd reccomend the DT Swiss, I have Open Pros too on another bike and like the build of the DT's better.

At your weight 28 hole will be plenty. Build them up with good quality butted spokes from DT Swiss, Sapim or Wheelsmith. Personaly I would recomend 3cross for front and rear. 28 hold laced radialy might be a bit twitchy on the track. Go with brass nipples also.

Rim wise you cannot go wrong with Mavic. The CXP33 is nice and offers some extra stiffness from being a little taller. Velocity rims are also very nice.

Just curious if that will hold true for the Mavic Ellipse that I recently purchased with 20 radial. But I believe Ellipse is under more tension by design. Any comments on how the Ellipse rides on the track?

I got a pair of Ellipses cheap and use them for training a bit. The wheels are nice and stiff, but I don't like the way clinchers feel on steep banking. I could get really expensive clinchers, but it Vittoria Pista EVO tubulars aren't that expensive and ride great.

The ellipse wheels are nice, Most people can get away with the radial lacing on that wheel because the rim is very stiff and takes up alot of the load. Its mostly enduro's and all round riders that use Elipse wheels. A 200lbs+ sprinter on any banking would find that front wheel tiwtchy at full speed. Alot of guys use those wheels at FCV without problem.

Re clinchers: Again, if you use a very good clincher tire you wont be able to tell the differance unless you a big sprinter. They tend to bounce a little at high speed.

I have ok ones on them (Vittoria Rubino Pros) but they feel squirmy compared to the EVO Pistas.

PUmping a clincher up as hard as a tubular track tire is flat out stupid. Mavics max pressure sudgested for the elipse rim is 130.... Higher pressures put a huge load on the wall of the rims.

Thats why tubulars are more common under bigger riders. They can be pumped up rock hard due to its circular carcas.

Yea, back in 1989 I had a pair of road tubulars rated at either 180psi or 200 psi, I believe it was a panaracer tire. I put them on a set of 28 hole mavic GEL 280's. Rode great. Try that psi on clinchers!!!


Can anyone remark on High(>150psi) or low(<140psi) tire pressure in relation to rider weight in regards to speed and handling (not comfort.) I'm asking this question in regards to track racing, not road riding.

Deep section rims are for low spoke count wheels. In theory the weight penalty isn't that important in a flat time trial. Zipp has some really great test data on their website. I have been building wheels on and off since the late 1970s, and the DT 1.1 is my new favorite. Also consider using the wheelsmith aero spokes (AE series). I am about 165 lbs. and I use 32 front and rear, with the aero spokes in front only, absolutely zero problems. I would advise against radial lacing on hubs not specifically built for that. You're asking the hub to take forces it wasn't designed to take.
