Hi,
I would like to know anyones opinion on disc wheels out there, basically my choices
seem to boil down to corima, zipp, fulcrum or campag. (local stockist) given that the last 2 are hyper expensive that gives me a choice of zipp or corima. If my pocket is making the decision i would end up with the corima, I was just wondering if anyone knew where the best value lies with a tub disc?
Surely a disc is a disc is a disc the world over as long as it is rigid, strong and aero…please correct me if i am wrong.
ps I dont have any interest in covers or clinchers.
thanks for the reply, never heard of renn, not all that many brands on this little island off europe, i kind of want to stay with what the local shop has as they will be glueing the tubs for me.
i never would have thought of shapes. The wheel will be going on a ceepo venom, or perhps a giant tcr with clip on bars if something happens the ceepo.
both corima and zipp have great hubs, but realistically you will be riding a disc for years before hub durability becomes a problem if you restrict them to race use. Races with torrential downpours are rare.
I’ve got a Corima disc and having ridden beside a zipp 900 disc before, and i can tell you the sound they make are different. The corima sound is lower pitched and slower frequency (when i first rode it i thought there was a big mack truck tailing me), whereas the zipp is slightly “choppier” sounding like a helicopter and much higher frequency.
For value, i think Corima is not that cheap in the USA so you should consider something like a Williams disc. www.williamscycling.com
They use the pre-dimpled Zipp 900 disc mold which is a perfectly fine solid disc, and the price really is quite good.

I guess you have not experienced an irish summer!! The retailers here dont carry williams as far as I am aware but i will check it out. I dont know what the price diff in the states is but here its about 500 euro between the corima and the zipp 900 and 850 euro to the sub 9.
Things will vary alot from frame to frame. If your frame has a tiny gap from the wheel to the seat tube a flat disc MAY be faster (Cervelo P series, Scott plasma, etc). If you have a “gap” between the wheel and the seat tube then a bulge or lenticular disc MAY be better (Look 956, most road bikes, etc). I don’t know the gap on a Ceepo Venom.
The above will vary also by the shape of the seat tubes, chain stays, distances between them and disc, etc. Lots of things to consider.
One disc is really not “faster” then the other, because the frame you will then put them on changes the frame and wheel aerodynamics.
+1. I have the Zipp 900, but if I were to do it all over again, I would go for the Corima Carbone C+. It’s stiffer and, in my opinion, has a superior hub. Plus it’s pretty easy on the eye.
there is not much of a gap on the ceepo, and the rest of the bike is quite flat.(stays and seatpost).
thanks for the info. Its looking more and more like the corima every day.
