Any ideas on a relatively inexpensive disc wheel? Lighweight makes a really crazy looking one, but I reckon' they're mighty expensive. The Renn disks are pretty cheap, I could always throw a surly converter on there...but who knows about those things for racing. Maybe I'll just hit the swap meet and pick up a used HED.
At the World Cup I saw these brown discs ridden by the eastern european/russian riders, as opposed to standard mavic wheel. I think I know where I can get my hands on one of these less expensive discs, but does anyone have any info on them online, so I know about where I should haggle to with this LBS?
Yessir. I think I can get my hands on one from an LBS down here. I'm not sure, though. They're not really on the shop floor, and I know about them because of some business I was doing for them. I don't know if he wants to sell them or not.
The Renn's are pretty cheap, and seem pretty good. They're flat, which is fine for the track, little side-on wind, which is the only place lenticular matters, from what I can tell.
Vomitron, I am not sure that the Renns use an actual Shimano hub. As far as I can tell the Fixxer only works on specific Shimano branded hubs, not the generics that are used for most "Shimano compatible hubs". I contacted Renn to see if they did a Track hub and they said no...did not answer my question regarding actual brand of hub they used for the SHimano compatible discs.
Ultraman....You listed Renns site and then had a line of 8 question marks...I was wondering what your question was.....
While many of the athletes riding at the World Cup were riding on sponsors gear...I did see the FluidDisks being used(by at least the Polish team..that is where the picture is from) I do not remember seeing any Hed disks in use there.....
The Dutch team has some Disks that looked similar but did not have any markings on them...so am not sure what brand they were.
Did you see that Araya disk? The one with the blinding disco logo? Man, that thing was brilliant. When I finally buy a disc, I'm going to cover it with a giant disco logo so as to blind anyone drafting me, including members of my team! Huzzah!
The UK national squad don't have a sponsorship deal, they source what they feel is the best equipment. (i.e. the custom made UK carbon bikes, approximately 2kg lighter than the equivalent Corima or Look frame). They mainly ride Sugino cranks and Mavic discs/5 spokes. (they do have some corima discs/4 spokes left over from the wheels they were using a few years ago, but these are now used for the youth/junior teams or for training)
The MDT disc wheel that you have a picture of is not a 1980s pre-carbon disc. MDT discs are made by Corima and just rebranded with the MDT logo. A close look at the hub design and you'll see that they are exactly the same.
so what's to be gained with one disc vs another? obviously, there's aero drag coefficient, bearing drag, but that's all a function of design (lenticular, dimples, flat) vs. conditions (sidewind, etc). is the big difference lateral stiffness? or is it MOI?
edit: well, bearing drag is a function of bearing type/quality.
You gotta admit though. Some bikes look good with disc's and some look like ****. I looked at a pair of IO and Compete wheels once on display. They are probably the nicest made areo wheels I have ever seen. Also the most over priced wheels I have ever seen! Even on employee deal! I think I could equip my bike with 404's and buy a 909 disc and still spend less than on Mavic.
