<p>+1 for brass nips. For the reason stated. When I had to replace a rim, ended up cutting out what should have been a re-usable set of spokes. Fortunately, they weren't CX-Ray$$$$ </p>

</p><p>The 404's are also loud because the carbon rims propagates the hub noise.</p>
I need/want a loud hub too, since much of my usual commute route is a multi-use trail. When I ride with my cousin the Zipp hub on his 404s drowns out my hub several times over and the pedestrians can hear him coming sooner.</p><p> maybe a DT 240? Is there something else or something new I should be aware of?

How crazy would I be to try and build these myself?
It would be worthwhile to me to know exactly how they are constructed. I'm just about positive that the small investment in the necessary tools would be worth being able to say I built the wheels myself, and having the confidence to replace a broken spoke, say, or re-true the wheels myself.

<p>It's not just the cost of the tools. Think about how much the little items you buy for Miata cost more than a kit put together by a vendor, who accesses better pricing. In other words, you will pay more for hubs, rims, and spokes; than you will for a built wheel with the same components.</p><p>But, you may want something special that cannot be found already built. </p><p>Building a a good wheel is not too hard. Read Jobst Brandt's book to find out how. See Prowheelbuilder.com for spoke length calculations.</p><p>I built 5 of the 6 wheel sets I own. You need truing stand, Tensiometer (Park Tool… the DTSwiss is a better design, but my oh my the price) and a spoke wrench. </p><p>Yes, it is satisfying, and you should end up with a better set, unless you know of an excellent builder. </p>

<p>n00b question.</p><p>My dad is shopping for new road bike wheels and I haven't gone wheel shopping in a long time. He rides a decent amount, group rides, with my mom, etc. Probably 50 miles a week.</p><p>He's been on the same Specialized Allez bike since the 90s and is slowly upgrading bits (crank, wheels, brakes, etc)</p><p>Budget is under 800.</p><p>Suggestions? I assume carbon, but not sure how deep, brands, etc.</p>

We've always known that fixies are an abomination against nature. Now Google has documented proof:
How fixed-gear bikes can confuse Google’s self-driving cars
By Matt McFarland August 26
Understanding the intent of a cyclist doing a track-stand is a wrinkle for self-driving cars to figure out. (Eric Risberg/AP)
Earlier this month in Austin, a cyclist and a Google self-driving car met at a four-way stop. This likely wasn’t the first time a Google self-driving vehicle has encountered a cyclist at a four-way stop. The company’s vehicles have driven more than 1.1 million miles in autonomous mode.
But the encounter featured a twist — the cyclist was doing a track stand.
The cyclist recounted the encounter on an online bike forum:
The self-driving cars are notoriously careful, and tend to brake when anyone else is moving forward into the vehicle’s path. In a track stand, a rider on a fixed-gear bike may shift ever so slightly forward and back in an effort to maintain balance. (Watch video of a track stand here.) Also, a rider doing a track stand maintains the body position typical of a cyclist in motion, not one that is stopping. For riders of fixed-gear bikes, it can be a fun game to never have to put one’s foot down on the pavement, but instead balance at stop signs and red lights.
While a human driver can easily see a rider doing a track stand isn’t going anywhere, Google’s self-driving car seems to be still be figuring that out.
As the cyclist recalled:
It apparently detected my presence … and stayed stationary for several seconds. it finally began to proceed, but as it did, I rolled forward an inch while still standing. The car immediately stopped…
I continued to stand, it continued to stay stopped. Then as it began to move again, I had to rock the bike to maintain balance. It stopped abruptly.
We repeated this little dance for about two full minutes and the car never made it past the middle of the intersection. The two guys inside were laughing and punching stuff into a laptop.
Despite the awkward encounter, the cyclist didn’t leave with a negative impression of self-driving cars.
“The odd thing is,” wrote the cyclist, “I felt safer dealing with a self-driving car than a human-operated one.”Self-driving cars could be a boon for cycling. If self-driving vehicles almost never crash, roads will become immensely more safe and inviting to cyclists. But for now, mastering how to interact with cyclists is a challenge for self-driving vehicles.
A patent Google received this spring detailed how its self-driving cars could identify cyclists and interpret their hand signals. It also mentioned the ability to identify a cyclist by measuring the distance between the pavement and the top of a stopped cyclist’s head.
Of course, until this summer Google’s testing was centered near its Mountain View, Calif., headquarters. In July, Google began testing in Austin, home to a lot more hipsters and fixed-gear bikes.
A Google spokeswoman called the situation a good example of the feedback Google wants to get from the community as its refines its software and tests in areas outside Mountain View.
The broader the experiences of self-driving vehicles, the better prepared they will be for real-world driving. The run-in also highlights the long list of rare situations the cars will have to master before they can replace human drivers. After all, what happens when a self-driving car approaches a downtown intersection with multiple cyclists on fixed-gear bikes, and a herd of pedestrians?
In a July report on emerging technologies, the research firm Gartner placed autonomous vehicles at the peak of inflated expectations. It wrote that inflated and unrealistic expectations have resulted from prominent media reports, despite complexity and cost challenges that the vehicles face.

The car got to the stop line a fraction of a second before I did, so it had the [right of way]. I did a track-stand and waited for it to continue on through.

My old racing bike. 6.24 kg (13.75 lbs). Once I had to have hip surgery, the Miata was the natural progression in search of fun times in a lightweight machine.
Yes, this entire bike weighs about the same as my flywheel.

Actually, I have a lighter bike now with Record/Super Record and Quarq power meter, but I never really got around to taking pictures of it. It only saw one stage race before my hips started to get super fucked.

</p><p>Thats what he ended up doing.</p><p>Found a LBS that was getting rid of some of last years inventory. Got them for like 40% off. Dropped like 600grams total so he was pretty excited. LBS threw in some service and will retrue the wheels whenever he comes back in.</p>
This <em>might</em> be the case sometimes, but most of the time you can build a set of wheels for less than it would cost to buy them prebuilt (depending on the cost of the wheelbuilder/retailer/etc. you would source them from). Go with aluminum clinchers instead of carbon. He sounds like he would have very little need for a set of carbon wheels right now, especially with a budget of $800 or less. If you have a local bike shop, talk with those guys - the should be able to offer you buying advice and any service assistance that he may need down the road. Most offerings from the big name brands like I mentioned previously (Shimano, Mavic, HED, etc.) offer plenty of wheels that fit within his budget that will roll very nicely for many miles.

Nope. The chinese frame is faultless, except for squeaky BB30 which happens on every BB30 bike. My new frame is PF30 which I was hoping would eliminate the creaking, but I haven't had much of a chance to ride it.
Nice to hear from a fellow weight weenie.

Also, my friends are pressuring me to do the Cat-5 state road race in two weeks, telling me to "get a podium while you can". I'm kind of thinking about doing it before moving to cat-4 asap, the goal is cat-3 in 2018 and then go to masters, shortly before dying of lung cancer.
