    how deep is too deep?

    when does the benefits of an aero carbon wheel become more of a hindrance in either ride comfort or wind?

    I live in a not so windy climate and was wondering how deep is to deep with carbon wheels?

    they would be used for fast group rides and races I'm 6'4 and currently 210lb trying to get down to 185-190lb would I be blown around on 60+mm wheels? or is this highly over exaggerated?

    was looking at a boyd package of an 85 rear and 50/58 front. or 85's all the way around

    edit: forgot to say I live in Florida...climbing is non existent and the avg wind at best is around 10mph or so.

    oh and anyone feel free to add pictures of their bike w/ 60+mm deep rims.

    In a similar vein, is a 38mm wheel noticeable? 44mm? How shallow can you go before the benefit is negligible?

    All depends on your handling skills. If you know how the bike is going to react to a crosswind, you will be fine. I've ridden 808's with 25mph cross gusts and lived to tell about it. Prepare for internet experts to tell you that you will die because of a crosswind.

    Edit: Just saw your weight, you will be fine with deep wheels. I weigh 150lbs.

    both bikes look awesome! so you like the staggered setup better than say the dual 80's?

    rarely will I ever see such windy conditions here thanks for the help

    anyone else?

    Thanks -- I prefer the staggered setup because I don't like the way the extra weight of the 88mm front wheel affects the handling.

    Move a little further east ... winds over here top out at 25mph and are more like 15mph on average December through April (even over the last week).

    That being said - I'm getting 66mm deep wheels.

    How about this recent heat?

    At your weight and the given wind conditions, you should be fine. I'm 120 and have taken my Edge 66mm front with a disc in back through a ~25mph cross wind with 30+mph gusts on my TT bike. I'm not saying I wasn't scared, but I managed to maintain control.

    If you're goal is weight loss and fitness, having to work harder to stay with the pack is never a bad thing. My race wheels don't come out until race day.

    Where do you live?

    I'm use to the heat its never been a problem for me but yeah it's been unseasonably hot so far June was the hottest june on record in Broward county ever. I live about 10 miles from the Beach...not too much further east to go!

    these will be used for race day, but I'll definitely ride them to learn how they feel

    thanks

    Ah, perfect!!! Definitely test them out on a bad day.

    LOL, there have been a lot of threads lately about wheels to go faster in non-racing scenarios.

    I think that all of the replys so far have overlooked one thing about the OP. "this will be primarily for fast group rides/races." This would make me skeptical about running a 60-80mm depth up front. Sounds like a good way to take out the peleton. Maybe you should consider the 60-80mm depth in the rear, and go with the 40-50mm depth range up front. This would give you good aerodynamic capabilites while not compromising handling.

    Lots of people race 60+mm up front and don't take out the peloton.

    I've seen plenty of racers take out chunks of the peloton without the assistance of deep rims. Just sayin'.

    Not too convincing when there are bandages present.

    I've ridden my sram S60 60mm depth wheels in 50 mph gusts and 40mph constant winds here in ND and SD and it was quite scary and I weigh 175-180 lbs. I currently have a set of easton ec90 sl carbon clinchers that are 38 mm deep and want less rotating weight and less wind affecting my bike.

    Seeing mjd's bikes keep making me think I should have gone deeper.

    I ordered the 50mm front and rear.

    Why did you sell these wheels?

    Wife wants a bike to take to the beach the week after next. They are listed but not yet sold. I did a 45 miler yesterday afternoon on them, I'll probably order another set in a month or 2.
