Eh. I've been accused of being a shill too many times because my posts tried to address all my questions at once. I assure you, i am NOT a shill. FFS go through all my posts if you want to make sure.

So let me ask you, what are the advantages of deep v rims?
I've only seen them on single speeds and fixies around town...

EpicSchwinn

Street cred.

Theoretically they're stronger.

Also theoretically they're more aerodynamic because the smooth surface of the rim is more aero than spokes hence more rime + less spoke = more aero.

Disadvantages: Most of the advantages are negligible in practice and they tend to be much heavier than a box section or narrow rim of the same material

Epic hit it on the head. Unless you're a pro-level racer there's no need for the aero advantage. In my opinion, in a big city they're less aero simply because of the cross winds coming down the streets between buildings. I rode a friend's bike with b43's on it and was getting pushed around by wind at every cross street.

Just my $0.02

Srsly.

No, but on a serious note, they are great rims.

they have a large surface for displaying snazzy colors

Deep Vs - real Velocity Deep Vs - are awesome rims. On the heavy side but it is possible to build a light(ish) wheel by using good spokes and light hubs.

and for people who are overweight and ride on harsh streets you can't beat a deep v. At least the back wheel

xkillemallx16

with the new rims being made, deep v's are becoming less and less relevant.

Scrodzilla

Not necessarily. That's like saying "With the technological advances the bicycle has made over the past century, fixed gear bikes are less relevant".

Yes, there are a lot of lighter weight deep section rims on the market but Velocity Deep Vs have staying power.

How about those new Foer 41 rims on RG scrod? I was looking at those, I was thinking about getting stronger rims for the super ****ty sidewalks/roads around here. Any feedback on strength?

Scrodzilla

They're decent and considerably lighter than B43s but personally, I'd rather use Deep Vs.

solbrothers

they have no advantage over a box section wheel on the street.

Nuggetross

anything deeper than a deep v is just unnecessary. b43's and the like are just ridiculous. and everyone knows that you get sicker skidz with deep v's, amirite?

redpear

also wheelies, leg over the bar skids, and quiksilver dismounts are all easier.

thirdgenbird

due to the cross section and strength you can build a wheelset with fewer spokes than a box section rim. keep in mind they are also heavier so there isnt much in the way of a benefit on the street. on a road ride i would rather have lighter rims.

in cyclocross the deep section wheels shed mud and push through sand better than a box section rim.

pkpyro

Ah thanks for all your inputs.

So would Deep Vs mean less going out of true? (since impact should be somewhat "soaked up" by the Deep section?)

Also, what material is the deep section made of? Carbon? wood? plastic? I can't quite tell

solbrothers

aluminum

As a disclaimer, I am a far, far, far cry from any kind of expert. However, I need new wheels, so I've attempted to soak up whatever knowledge I can of late. What I have gleaned is that deep v's are a bit on the heavy side and offer an aerodynamic profile. If you aren't racing the aerodynamic bit is a load of bunk and not worth considering (and if you really are racing you're aero wheels are probably made of carbon and not Al). The heaviness is a bummer, but it plus the profile does contribute to wheel strength. So if you beat your wheels up it'll save you. And if you're trying to "faster" wheel, it offers you the opportunity to use reduced spoke counts to make a lighter/presumably faster wheel.

How you determine how few spokes you can get away with is a science I have not yet figured out. If anyone knows I'm all ears.

jimmytango

Rougher road/harder riding (i.e. freestyle) means more spokes in the front. That and tons of torque determine the amount in the back. However, these are very very generalized statements. Stiffness plays a factor, as does spoke gauge. You know what? Imma let a mechanic weigh in on this. Scrod, where ya at?

Not necessarily. A shallower rim will be more able to flex a bit on rough surfaces, which will do more "soaking up" (absorbing) of impact/vibrations.

Man, after being hit with wind one day, I really don't want to run deep rims any more.

bluepencil

haha!

Guy had some cheap stock wheels on a Felt road bike, maybe Alex rims. Broke spokes, but too cheap form a complete rebuild, so... More broken spokes. And these are fairly heavy, too. Set him up with Deep V Velocity Comp wheelset, 28h, radial front, 2x rear; up from the original 20f, 24r spoke setup.

Deep V wheelset was lighter than his stock wheels and will be much stronger.

Gave him the option of lighter rims--was going to suggest Fusion or A23--but he def perked up at mention of Deep V's, and was over the top pleased with them.
