FWIW, my rival stuff on my cross bike has been beat to hell and keeps working. The SRAM neutral mechanic suggested getting one of those compressed air containers (for cleaning electronics etc.) and blowing it clean and said it will work like new.
William, you should send a tweet out to Lance Armsrtrong. He bought a big piece of SRAM just before he announced the comeback 2.0. Of course Astana and RadioShack used SRAM. Of course sales spiked when people saw Lance on SRAM. Of course he instantly profited from his investment. Of course the comeback was all about raising global cancer awareness. Of course Lance got huge appearance fees when he raced in the Giro and in Australia...wait, what was I originally talking about???
Chris: you just made actualol
I ♥ shifters.
back to the bike fit conversation:

Any thoughts about a 2008 Raleigh Prestiege?  There's one for a very nice price that I'm looking at.  Full carbon frame with a mix of Ultegra and Dura-Ace.  Basically would be the nicest piece of equipment I've ever owned, but don't know anyone who rides one.
why do you need a new bike?

is it for Her Grace?
Tito,
     Nooooooo!  I thought you were part of the CaaD9 4 Life club.
caad8

but at least it's a caad
I will always be a CAAD (and a cad, too, if you ask some ex-gf's).

My folks moved last year from Poughkeepsie (last stop on the Hudson line of Metro-North = bikes cool) to Germantown (Rhinecliff stop on Amtrak = bikes not cool) and schlepping the bike has become a colossal pain in the fundament.  I've basically made my whole family hate me on various visits by this point, because the riding up there is spectacular and I usually insist on having my bike.

The plan now is to get a new road bike by the end of the summer and bring the C'dale up to the folks and leave it there.  Since Grace will be living p/t up there this year, she'll also get use of a road bike when she's there.  Voila.

So - any thoughts about the Raleigh?
oh . . . to have the same bike size as your wife!

i wish! mine has a sweet cannondale but her saddle is about 2 inches too high for me! [thepainofbeingshort]
Yeah it's pretty sweet.  We also wear the same shirt size - we share button-downs, f'real!  Kinky!
ok

that's enough out of you
whaa?!  I wanted to talk bikes - you made it about Emasculated Little Man's Syndrome (ELMS).


racking my brain to turn that acronym into ELMO

I just wanted to ask what's peoples take on a good aero front wheel for the velodrome? I was looking into HED H3 (or H3D) wheels, but Im not sure if they really live up to their hype and are just all flash no substance like aerospokes. Not looking to buy a mavic iO though haha just something way more affordable.
Because of how mellow the banking is at Kissena, and the fact it's outdoors, I just use my front road race wheel with a bolt on skewer. It's a 90mm carbon tubie. What do you have on your road bike?
BBRight & BB30

What is the real deal here?  Can I run a BB30 crank on a BBright bottom bracket (like my Cervelo R3?)

I called Quarq and they sent me the attached PDF detailing how it was possible.  Just wanted to sanity check this with the collective wisdom of the team :)
Second tech question of the day: 

do the new SRAM 2012 chainrings demand a 2012 SRAM front gruppo or can they be run just fine with a 2011 or older SRAM front derailleur?


H3 isn't the fastest aero wheel out there, but it is pretty aero across most yaw angles.  Vertical and lateral stiffness is pretty good as well.  Vertical stiffness might work against you at the Kissena velodrome, but put on a 23 or 25mm tire and it will work out.

BB30 in BBRight.  Quarq's website says the Quarq BB30 fits in the BBRight BB.

SRAM2012 Rings can be used with any front derailleur and probably any chain, but definitely all 10-speed chains.
DON'T USE THAT PRESS-FIT CRAP, Jules.  It ain't smooth as butter. It wiggles.

I've done a little research on this, and from what I gather SRAM's compatibility shit for the 2012 gruppo are all hype and no substance. you can basically run any mix match of front der / rings.

some bb30 cranks. the sram quarq has a slightly longer axle then a normal bb30 crank, say a hollowgram for example. they do this so they use a preload ring instead of a wavy washer. removing that preload ring frees up enough room on the nds of the spindle to work on a bbright frame.
@mattie davitt

I actually dont have a road bike yet (I WANT ONE SO BAD!) i have a track bike and i have mavic open pros on it with dura ace hubs. I love those wheels but since all this talk about carbon aero wheels has been going around, i felt like maybe I should look into getting some new wheels for the track
Aaron, dude - we haven't met, but I just want to say that most of the time, the money would be better spent on a couch or training plan, or anything else that helps to improve YOUR engine before you start buying new stuff.

Kissena is not a smooth track, and riding nice wheels (especially tubulars) out to the velodrome invites fretting/anxiety.  Unless your wheels are 36hole anchors, what you have is probably great.

If you need to spend money, buy some dope tires (Michelin ProRace4's?) and latex tubes - that will be a big performance enhancer if you're running heavy rubber.
Aaron,
I would second what William says. You're better off with an smaller upgrade of tires and tubes, and you'll see a huge performance gain, without having to find a place to store a second set of wheels.

William a couch is nice, but I don't know how much performance gain a sofa will give you. Especially when you take it to the drive thru.

You have GOT to get a good couch.  Very important for recovery and pre-race visualization.

Out of nowhere I blew a spoke.

I did an awesome ride this morning. Put the bike away. Came back, spoke was busted.

I've never broken a spoke without some obvious force being the culprit. It would appear the bike was just sitting there and it snapped. Is this common? 

One key piece of background: I had my wheel trued at Ride Brooklyn. They told me the rim was slightly bent and that because of that they had to over-tension one side to get it true. They said there was no other way to get the wheel spinning true, and that it would take the wheel slightly out of round. 

I'd never heard of that before so I was slightly worried, but figured they knew what they were doing. I also noticed that some of the bladed spokes are a little twisted. Given Jules's experience at Ride, I'm a little skeptical.
@ Aaron, the rubinos are totally fine.

@ Ryan - they screwed up a truing a year ago. I had to take it to NYC Velo.

I blew a spoke a few weeks ago and Ride replaced it an re-trued. So far, so good. Fingers crossed.
P.S. when a bike shop says something like "well it had to be done this way because" I'm a little skeptical. I think it means they don't have the time / energy / skill to do it perfectly. Or the right way.

That is what NYC Velo ended up doing with the wheel ride couldn't get true. They took all the tension off the spokes and started more or less from scratch. It's been perfect every since. But I'm sure it was a lot harder than just turning a few spoke nipples.


I once had a wheel that gave no end of trouble. I was constantly tinkering and replacing pieces of the freehub in an attempt to get rid of an annoying noise. Eric dubbed it my 'Emma wheel' named after my teenage daughter (don't mention this to my wife). I finally delegated it to cross where I couldn't hear - or no longer cared about - the annoying noise. After a season or two, the rim blew apart and it sits in a pile of other dead wheels in the basement. Reason for my story is to convince you that your wheel is hopeless. Overtensioning a spoke is a last gasp effort to save a dead wheel and was bound to fail. Lucky it did so in your house rather than on the road. Save the hub for a rebuild. The rim is toast. RB was in an awkward spot. No customer wants to hear that their rim is toast. Some other bike shop will always be happy to take your money and claim to fix it.
