sorry, this is probably the eleven'teenth time this has been posted, but what's the consensus on mavic open pro's vs. the velocity deep v's? i'm a consensus kind of guy...

one is box, the other is aero

Not to muddy the waters here too much but if you are considering the Open Pro also look at the DT Swiss RR1.1. Same sort of design but they are a little lighter (10g per rim) and they are a couple of bucks cheaper too. https://www.dtswiss.com/index.asp?fus...ikedetail&id=8

just get the open pros,they have eyelets

Can you elaborate on the benefits of eyelets? stronger, perhaps?

Eyelets are supposed to make for more durable wheels by reinforcing the spoke hole, but I believe it depends on how they're done. The MA3, for example, uses single eyelets which actually require a larger hole and can weaken the rim leading to spoke pull through. The Open Pro uses a double eyelet--also known as a socket--so that the both the inside and outside surface of the box section end up supporting the spoke tension. Using stainless sockets also allow you to use aluminum nipples if you're so inclined.

The Deep-V has no eyelets, but it's not really a detriment in practice. They can handle a much higher tension than the Mavics. They are also stronger due to their deeper cross-section (there's no aero benefit for such a low profile though, you have to get quite a bit deeper for that), but heavier.

I really like Open Pros. Strong, light, and wicked easy to build with because they come so true off the peg.

i use open pro's, but mainly because you cant get deep v's in the UK.
does anyone know where i can find them here?

Ok, this is nothing like anything else... but I just built up a pair of Mavic T520 ceramic rims and am currently all about them.

Mavic CXP-33s are quite nice, I've had good luck with those(and CXP30s), not such great luck with openpros or deep vs.

But, the Deep Vs are stronger in the area of the rim that doesn't count: the bottom. (And at a significant cost in weight: ~100g x2) A rim should be strongest on top where you put your tire. In this respect, both the OPs and DVs are equally strong.

My go to rims are always Mavic OPs. And a well-built wheel by a competent wheel builder will be strong regardless of rim.

What about the Velocity "Fusion" rim? I have two pairs of wheels with this rim -- Dave Thomas from Speed Dream Wheels builds with it -- and have had no problems so far. (Actually, one set is on a CX bike, so it takes a beating well.) It's an aero design, no eyelets, but not quite as deep/tall as the DV. Not sure about weight and cost differences from OP or DV.

if you're not racing, it's a looks thing when you get down to it, really.
and deep v's come in colors.

whats the benefits of a ceramic rim, I've seen them for sale but never actually seen anyone with them around. Are they lighter? they seem to be more expensive so just wondering what the differences are. Don't the OP or CXP come in ceramic?

Ceramic rims are irrelevent to fixed gear, since their purpose is better braking surface. A little heavier, a little pricier. Not worth it.
