only in bfssfg do people let things 'cool down' to room temperature after they take them out of the freezer.

Yeah, I'm not sure about those either. When I think of deep V's, I still think Campy Shamal and the like. Good alloy and good design and manufacture.

I thought this thread was dead...

I think you just divided by zero.

I just bought a set of black SUn CR-18's laced to some high flange cartridge bearing hubs. They are stronger then the old steel Schwinn Wheels I had. But I do notice a difference in momentum. I like them though. I'm not as afraid to ride over bumps, or even do some light trails. I've got 700x35 tires on them with a bit of tread. It looks sweet

What are you talking about? I can't tell what you're saying.

My favorite rims are the old Mavic GP4s, and the old Campy Omega aeros, They were simple, strong, good looking, and after years of use, required only minimal truing. How well your rims hold up in city riding depends as much or more on the tires you are using.

I love the appearance of deep v's, and ever since I bought my singlespeed, now fixie, I had the intent to buy new wheels. I'm a web designer by profession, so aesthetics mean a ton to me. No real rhyme or reason other than pure looks.

However, for the past 5 months or so of abusing this bike on the streets of Honolulu, which are *constantly* under construction and riddled with potholes, like most other metropolitan cities, these things have held up like no other.

Salsa Delgado 36's laced to Surly hubs. They are still not even slightly out of true, and the spokes are tight as some high school snatch. I love them actually. Thinking of having them mediablasted and then powdercoated, but would prefer just pure anodization.

My hubs are pretty beat and although my LBS sort of overhauled them a few weeks ago, seems like there is something fishy going on. Lots of side to side play. Maybe time for new bearings?

Anyway, I don't think you "need" deep-v's if you need a strong wheelset, my wheels are a testament to that. Love them.

IRD Cadence Aeros are a very legit Deep V alternative. 460g a rim, arrive true and round out of the box and build up with a very even tension, and take potholes nicely.

I was looking at deep v's on ebay and was wondering if they come with breaking surface on the rims. If not, does it cost a lot to place one there? thank you!

They look like DT Swiss rr 1.1

This thread is like a car crash. It is horrible, but I can't turn away - I just keep reading. So many people saying things that seem completely nuts.

First, my take on this. Deep Vs are strong. Are they the "strongest?" Who knows. They are used lots in tandem wheels (need to be strong for weight) and tons in low spoke count wheels (rim needs to take on more of the strength). However, there are some nice alternatives to Velocity (such as DT) which have alredy been noted. Do you like Deep Vs? Get some - they are a nice rim. Do you find them ugly/heavy/etc? Don't get them, you have selection.

Ones that have been covered before:
To the person who said the Deep Vs are the only rim that will get 'untrued' from street riding - you are wrong.

To the person who said that deep Vs are the best for street because they are strong - go buy a nice thick sheet of solid metal, cut it into a disc, run an axel through it, and use it for your wheelset. There are lots of considerations besides strength for selecting a wheelset. I have no doubt your proposal will be strong, but will it be light? Will it look good? Some of these are quantifiable and some are subjective. Point is, there is no correct answer, and lots of people find Velocity Deep Vs to be too heavy for their strength benefit, particularly with lighter options that are roughly the same strength.

These haven't really been mentioned skeptically yet:
This whole "freezing the rim" thing sounds completely nuts. Do they do it? Maybe, but I doubt it is to acheive a higher spoke tension. The goal of a well built wheel is not to get the highest spoke tension you can - I can over tension a wheel by hand just fine without going near a cooler. An over tensioned wheel will go out of true quite easily, so you really don't want that. Again, they might subject the rims to cold temperature for some other reason - but I really have my doubts. It sounds very intensive, and for what purpose?

Finally, the "are deep vs used in cyclocross" arguement about European riders seems a little off, because you are arguing that Deep Vs are used because European riders use deep section carbon rims. Carbon rims are not Deep Vs. North American 'cross riders use carbon rims as well. We did quite a nice buisness with Zipp 404's 'cross model. I do agree with you that deep aluminum rims seem to be getting less popular (see Reynolds dropping much of their alu rim wheelset line last year) as carbon gets lighter/stronger/cheaper.

I like new people, welcome to the forum. This is a question that comes up a lot, so feel free to search for more info, but in short, Velocity Deep Vs come with or without a braking surface. If they do not have a braking surface, you cannot machine one on, because you will ruin the rim.

idiq

For the record, it is my impression that I misunderstood the 'shrinking' and then high-tensioning process used. It is not, literally, via freezing the rim to shrink it.

However, Mavic and A/C do indeed use a process to get extremely high tension spokes, for instance, on Mavic wheels that come pre-built the shop can often re-tension a nipple to a single spoke in case of it breaking, as the high tension of the others will not effect the now lower tension of the replaced spoke.

No, I do not know why such a high tension process is used, it was my impression that such a technique was to prevent the wheel from coming out of true as easily.

i have a front 18 hole radial laced deep v that goes out of true within a week of my normal commuting

geoffvsjeff

This still seems like bad info.
1. Your last sentance (if I am reading it correctly) is the definition of a wheel out of true (one spoke w/ low tension surrounded by others with high tension). I have no idea how this would result in a true wheel unless the rim is crazy strong.

2. I have replaced spokes on various Mavic Ksyrium models (btw, expensive proprietary spokes suck) and AC 420s. While I don't remember specifics, I can guarantee you that I used a tensionmeter on at least some of the repairs, and never noticed unusually high spoke tension.

3. Again, you don't want really high spoke tensions. It makes for a bad wheel. This is NOT desirable.

Here is a table with tension recommendations off of the Park Tool website:
https://www.parktool.com/repair/readhowto.asp?id=128

Spoke tension is a tricky balancing act, and is subject to debate in another thread. Different shops often have variations on tables like this (usually depending on the preference of the master mechanic and/or owner), but I don't see any reason why Mavic or AC would want to get really high spoke tensions.

I don't know if this is where your idea comes from, but there are people who feel that machine built wheels, in general, have higher tension than hand built. I am not sure if I agree with that or not, but I do know that the difference is not drastic. I also do know that everyone (or at least almost everyone) I know who has or has ridden true hand-built-entirely-by-a-human-being wheels likes them better, or at least the same, as machine built wheels.

geoffvsjeff

Stop there. Is this supposed to be sarcastic or a troll? I will assume not, just in case.

Any wheel with that low a spoke count and radially laced is going to give you problems. If you are using this bike for commuting, get something w/ higher spoke count and a traditional 3x lacing.

the pope

Just my opinion, but a surefire way to hobojank up a bike's aesthetics is with lime green deep-v rims. The leisure suit of bikes. However, the return of box shaped rim is the harbinger of the nut-cupper shorts returning to the NBA. Noice.

You should read his book

but it's a deep v they're strong

Me nether, and it's my quote that iDiq is referring to. I said that in my experience with Deep V's vs. CXP33s, the Deep V has been a lot more resilient. I don't recall performing any mathematical operations....

skeem

18 spoke radially lacing is only good for racing front wheels that arent intended for real city use. hell, paul wont guarantee the warranty if you radially lace the hubs. pauls the man, i talked to him on the phone the other day.

91MF

if i get deep v's and lace them to some cheapo formula hubs and not phils will hipsters come to my house at night and kill me?

Enk1du

yes

geoffvsjeff

Ditto w/ Shimano (radial lacing = void warranty).

I did not talk with Shimano on the phone the other day.
