    Well the SLR is considerably less expensive than the Aeolus.

    I had a set of Cosmic Carbone SL SSCs that were my favorite wheels. Buttery smooth hubs and absolutely bomb proof. I have heard similar stories about the Aeolus and the new SLR. Don't really think you could go wrong with either. So price maybe deciding factor.

    both are good choices but i think that if you are going to pay retail.
    assuming that your not getting a deal on either of these,
    maybe you should think about a hand built wheelset
    for example
    edge 1.45
    sapim spokes
    tune hubs

    would be cheaper than the bontragers
    just thinking outloud...
    if you are deciding just between those two wheelsets
    i would say the bontragers.
    i have a pair that i have raced cross on for 3 years
    i weigh 195
    so we know they are durable

    ok as for the aero factor
    the mavic is 52 mm deep and weighs 1595 g retails for 2000$
    the bontrager is 50 and weighs 1610 grams retails for 2800$
    the edge is 45 clincher or tuby

    if you want to get really aero then you should get the edge 1.68 which is offered in a clincher or a tuby
    the huge advantage that the edge has over the mavic aside from durability is that it is a full carbon clincher and weight
    so the mavic between to 3 is the most inferior but its the cheapest

    as for the differences in the aeolus it has dt 240 hubs
    these are heavy
    and flexy because the flanges are so narrow
    plus they are a low spoke count which does almost nothing for the aero factor
    and makes the wheel even flexier!?!?!
    if you want to build a sweet wheelset tune hubs are the same price
    handmade in germany
    lighter
    and have much wider flange bodies that build much stiffer wheels
    so if you are willing to pay full retail for the bontragers get a hand laced wheel
    it will be lighter
    stronger
    stiffer
    last longer
    and may even cost less
    unfortunatly i do not have any pics of that specific wheelset because the edge 1.45 just hit the market
    here are 2 examples of wheels and prices...

    edge 1.68 clincher 68mm deep super aero
    tune mig 70 and mag 180 hubs 20/24 spoke count
    sapim cxray spokes
    1460 grams +- 10 grams for rim weight fluxuations
    cost labor + shipping + parts 2443$
    light and super stiff
    this is the heavier pair

    lighter pair...
    edge 1.45 carbon clincher
    une mig 70 and mag 180 hubs 20/24 spoke count
    sapim cxray spokes
    weight 1260 grams!!!!!!!!!! insane for a clincher
    cost is 2443$
    this is an insane wheelset
    this is what i would get personally
    good luck

    Cool Mavic SLR or Aeulos 5.0

    Not sure about the SLR, but I rode the previous Mavic SL and they were decent once you got them up to speed. The weight was a bit much on the climbs though. Aeolus 5.0 were definitely a step up...lighter and full carbon made the ride more plush. I still think Bontrager makes one of the best wheels around for the money and that's comparing them to my Campy Hyperons and Bora Ultras. What sold me on Bontrager at the time was the 5 year warranty. I recently broke the rear hub on a set of XXX's that were about three years old and Bontrager sent me a brand new wheel two weeks later. Now that's a great warranty. If only my Campy's and Mavic CCU came with the same warranty.

    Disagreed. I think that the reason most people think carbon rims overheat is because of improper braking technique. If you ride your brakes non stop for 20 or 30 minutes, they are bound to overheat. You simply have to be more conscious about waiting until the corners to brake.

    Dude..you sell very light Edge builds...they are all round wheel sets...do it alls. If you're going down a technical descent you're screwed cause you have to ride your brakes or you will die...you can't wait for the corners. Carbon clinchers are not good for climbing steep technical climbs...but your sub 1400 gram builds encourange climbing and often promote the face that now they are light enough to climb with. I'm sorry but I will take a 150-200 gram weight penalty and not have my tires blow out. And trust me I am speaking from experience. Every manufacturer bullshits about how they have new "resin" braking surfaces or whatever claiming they have all but eliminated overheating....talk to any experienced rider/racer and they would never ride a carbon clincher.
