Depends on what sort of riding you do, aero wheels are good for flats, light weight for the hills.

One of the biggest myths going is that lightweight wheels offer some significant performance advantage. They don't. Aero rules until the road grade exceeds 10% or so, after that weight--actually moment of inertia--starts to dominate wheel performance. Now before read too much into that, there's this: moment of inertia doesn't start to dominate because of its great effect. It starts to dominate because aero benefits fall of the table at slow speeds. Moment of inertia benefits just decrease more slowly. MOI is still tiny.

What really matters is body weight.

With that get aero wheels. I've got a set of wheels built with 55 mm rims and weigh 1345g that climb at least as well as the 880g wheel set I used to have.

You don't see pros climbing on 808s, but since you live in the UK. Go aero.

But you see pros climbing on Boras, Zipp 303's, Zipp 404's, and so on. So much for the pros not climbing on aero wheels myth.

It's time people get a reality check and realize this whole "rotating mass" thing with bicycles amounts to a whole lot of nothing. Do the math. Do the science. You'll see what's already been verified. FYI, the math and science show the best possible results, for a given set of conditions, for the rotating mass crowd, and those results are miniscule. In the world, the differences are even smaller.

You've obviously not climbed too many hills in the UK have you. They might be on the shorter side when compared to mainland Europe but they're generally fecking steep.

Steep. Shallow. It's all the same: rotating mass isn't the issue cyclists think it is. It's a mental thing. Full stop. Even the weight of wheels isn't that great. The only problem I see with climbing with 808's is possibly dealing with fickle winds, after the climb, and on the descent.

It be nice if one of these rotating mass believers could offer up proof of why their belief is true, but they can't: it's not in the math/science. It's that simple.

It's time to grow up, move on, and blame the suffering on a climb on something else.

Whenever im at the LBS and I hear someone talking about saving x amount of grams by paying and extra 500 or whatever, it always makes me laugh. Most of the time, the weight youre saving is the same weight you could lose by taking a piss before the ride. Also, as a rather large guy (220lbs) I cant warrant buying super lightweight stuff until im at a lighter "racing weight)

My vote goes to aero. The time difference bw shallow and deep rimmed wheels has been well documented, regardless of the weight difference. theres a good reason companies like Zipp spend so many hours in the wind tunnel. I recently read that Giant teamed up with a Formula One racing team when designing the new trinity sl TT bike
