I once had to wrap about 20 grams of electrical tape around my seatpost to make weight, and I'm not a weight weenie at all. I know a 5'2"-ish woman racer who had to put a length of chain in her seatpost. I've seen a lot of people tape hex keys and the like to the top tube.

Basically, 15-30 minutes before each event, the rider is required to bring his/her bike to Bike Check. There an official measures the dimensions and checks the weight to make sure that it is legal. Then the bike is quarantined until the race starts and you are marked off the list as having been checked. The bike is put on a bike rack where you can't go fiddle with it...unless you bring it back through Bike Check again.
I've heard similar stories of bikes not being 15 lbs and having large allen wrenches taped to the tubing to make weight. I've even heard of one athlete installing SRM Power Meter cranks (which are heavier than normal cranks) but not using the computer just to make the bike weigh enough. This usually only happens with the x-small bikes (48-52cm) for the ladies.

I once asked a small elite woman about her power (after noticing the SRM when we were sitting around the infield) because I had been doing numbers on power vs. predicted mass start test time. She shrugged and said she'd never hooked it up and just used it for the weight.

I suspected that...
That I'm neither small nor a weight weenie and I still have to add mass to make weight is an indication that UCI needs to treat track weight different from road weight. I had a stock S-works Langster frame with specialized tri-spokes (not known for low mass) and aluminum bars, and I had to add weight. My Giant has a couple advantages-- I put a really stiff heavy stem on it, and it's got those monster steel inserts in the track ends that double the weight of the frame. So I think it comes in right around 6.8 kg.

It looks similar to this:

The really sad thing is that a lot of small bikes end up weighing more than larger bikes because the manufacturers don't spend the effort to make high end bikes in small sizes. My GF rode a tiny (43 or 45 cm, with 650 wheels) steel Fuji last year in the 508 that was about 22 lbs. The converted steel road bike that I rode was about 18. This year she brought out her old steel Osell track bike and we changed the fork and have it down around 18. Her extra small Jamis Xenith weighs more than my much larger BMC Racemachine. Some of that is in the stock wheels, but some is in the frame, too.

The two extremes are:
- Dedicated Time Trial bike geo
- Dedicated Sprint bike geo
Mass Start bikes are a lot like road bikes.
The Electron bike is designed for Time Trials, but they have sprint bars on it to make it look aggressive.
Nice.

He doesn't just make the same bikes in a few common sizes and paints them the color of your choice and calls it "custom". (That's what the custom Trek Madone system is.). He actually talks to you about how you plan to race on the bike and makes decisions on every angle, tube length, and tube thickness just for you.
Outside of the S/M/L frames that he makes in his spare time, every custom Tiemeyer Signature frame looks the same, but they are all unique in some way.
BTW, he's an actual engineer with some sort of engineering degree. Not just a guy who builds frames. He designed helicopter blades before he was a bike builder.

I think he's a master frame builder. Seriously.

I ran into a speedbump with my builder about 2 weeks ago (Stanridge) and immediately shifted my attention towards Tiemeyer. My build is still on but if Adam agrees for us to just go our separate ways I think I'll do that. Going to get a custom Satellite if so, can't believe the price considering it comes with an ENVE fork and a CK headset

new question
is it normal for carbon cranks arms to creak and make noises when there's a lot of force being applied to them? mine sound fine 90% of the time, but if I stand to climb on them, they're noisy as hell and it's been like that since day one. bb30

I've used carbon SRAM Force and Red cranks on my road bike with no creaking.

Hey dude, I've noticed that when I get above 120-130 rpm I start bouncing around a little bit. Why is that, and how do I fix it?

Are there such things as shims for cycling shoes? When I use vans and platform pedals, I notice that my feet sort of spill over the sides, and my feet arent parallel to the ground when I pedal, and thats more comfortable than using clipless pedals, and having my feet pretty much parallel to the ground.
Edit: I found this: https://www.specialized.com/us/en/ftr...sshoes/shimkit
but are there any other options?

But try moving your cleats closer to the body first. This will allow your feet to be as wide apart as possible. Do that before spending money on the extenders.
You may also want to adjust the angle of your cleats to match how your feet want to set: | | or / \ or \ /
