So I need some aero wheels. Through team sponsorships I can get Mavic wheels at like 45% off retail and Zipp at 35-40% off . I can also pick up a used Zipp Super 9 disc for around a grand (USD). I originally thought I'd get a Lightweight disc but have decided spending over 2K on a disc for the limited use it would get is not worth it and I am therefore strongly considering a used Super 9. The Mavic Comete is also an option considering the big discount, but it is on the heavier side.
So my deep wheel options include Mavics (CXR 80 I guess), 808 FC, Enve 6.7, Enve 8.9, and possibly Bonts. Like I said, I want to use this wheelset on my road bike when the conditions merit, not just the TT bike. User reviews on the Mavic deep wheels are limited, so despite the impressive wind tunnel results I don't know how they'd handle in a road race or crit. I know the Bonts also do well in the wind tunnel but I don't know much more than that about them. Because I know less about the Mavics and Bonts, the 808s and Enves currently sit the highest on my list. I know guys that own the 808s and the rear often gets used on the road bike but the front almost never. I cannot find any road bike useage/handling reviews for the Enve 8.9s but I assume they would be more aero than the 6.7 for use on the TT bike, just don't know how much more aero. I know the 6.7s, although not as light as my mid depth wheels, could make for a nice road racing wheelset - but are they aero enough for TTs? Oh, and the LW Fernweg, due to the lighter weight and aero properties, would be my top pick if someone could source these to me for less than 4K, but I do not currently have a source for discounts on LWs.
OK, I've babbled enough! Tell me what to get! Do I get a disc? And which deep wheels? Or do I just get a disc and use one of my other wheels for a front on the TT rig? Too many options!
However, if mixed TT and road use is desired then a pair of 808s would be a better bet. As has been said, the 303 can be pressed into service for super windy days.
I think part of the reason you don't see many 808 pairs in road races is down to aesthetics/handling. In non time trial situations, an 808, 404 combo is arguably a better all round mix of weight, aero, all conditions usability and aesthetics.
It really depends on where your priorities lie.
I know guys that love the 808FC for use on the rear for road/crit racing but they all complain about the front being unstable in winds, not stiff enough, and just porky so for these reasons they run a 404. I'm not buying a 404 too but I do have the 303s. The 2012 808 FC reportedly has some sort of increase in stiffness over the 2011 FC for what that's worth.
Regarding the Mavics, the CCUs are a fantastic road racing wheelset but not sure they hold the aero candle. I understand that award goes to the CXR 80 but I don't have a set to demo and don't know anyone with first hand experience. So don't know how they would serve for double duty on the road bike. I did find one demo review that said they were not good in the wind or rain. Also don't know anyone that's used the Comete disc. So I am just lacking sufficient info to pull the trigger on Mavics and any first hand use of these would be helpful.
Thanks again for the input.
This chart is pre-firecrest, but it gives some idea what you get by using an 80's deep rear with a 50's front - a pretty negligable 1 watt saved......and if you are road racing you've added a 1/4 pound to the bike at the outer circumference of one wheel. http://www.spinlitecycling.com/ZippAeroEdgeFlyer.pdf" onclick="window.open(this.href);return false;

You already have great road racing wheels, so let's focus on the TT...
Enve 8.9 with Alchemy hubs would be my pick. Low drag and low cross wind issues. If you aren't under UCI rules you can put a cover on to make a rear disc, but I wouldn't bother.
That's a sweet table, handn't seen that before. Would be cool for Zipp to update that with their Firecrest line-up and include the Super 9.tommasini wrote:This chart is pre-firecrest, but it gives some idea what you get by using an 80's deep rear with a 50's front - a pretty negligable 1 watt saved......and if you are road racing you've added a 1/4 pound to the bike at the outer circumference of one wheel. http://www.spinlitecycling.com/ZippAeroEdgeFlyer.pdf" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false;
Thanks, I'll look into cost for this set-up but that may be a grand more or near double my cost for 808s, or in other words cost of 808s + disc = cost of Enve 8.9s. I like Enve, but that's a tuff pill to swallow. I do have Alchemy hubs laced to Edge 38 clinchers and Enve 45 tubs. Both sweet wheelsets - maybe I should just call up Enve for a sponsorship! Unfortunately, their home built 8.9s only come with DT 240s, which would not be my 1st, 2nd, 3rd, or ... choice of hubs.WMW wrote:Enve 8.9 with Alchemy hubs would be my pick.
But as said above you have really good rr wheels already so would be better to get a specific set for TT only.
