hello
does any one know of a CHEAP carbon track frame that is still stiff and verry good with sprinting
thanks

-cheap
-fast
-durable

pick 2 only

durable wasn't in his criteria, he said cheap and stiff.

the actual criteria are:

1. cheap
2. lightweight
3. durable

maybe by fast, you mean lightweight though. But fast comes from the legs, not the weight of the bike (although it can make a bit of difference). Honestly though, spending extra for a more lightweight bike so you can shave seconds off your time between lights is pointless. It's funny how no matter how fast I ride, I will end up at a red light and most of the people i over took who were riding mam charis will have caught up before it turns green again.

I also think that buying aero rims for aero effect is pointless unless you wear lycra and have clipless road shoes (and are in a race where every second counts).

It's fun being in the 5s and seeing other 5s riding top of the line group sets on top of the line frames with top of the line wheels, and then getting ahead of them on my 22lb bike with box section rims. I want those bikes >:C

Odd that they include a fork, but not headset.

yes please buy this bike and when it explodes come back and tell everyone about it.

Did you plant a bomb in it?

Or do you have some insight into these frames having design flaws?

Or are you one of those people that just thinks carbons gonna explode when you touch it?

Im betting on 1 and 3.

Try this Aluminum frame instead ...

Iv never liked carbon but that Planet X is pretty intriguing. Hmmm...

Caveat Emptor!
TofuPowered has planted bombs in the planet X bikes!
Really you should be paying more attention, I just saved your life.

Cheap carbon is not something to experiment with. It's not really a good place to cut corners with the process or materials.

Especially when its been compromised by vegetarian extremists

But in all honest look through https://www.bustedcarbon.com most of what you see on there are nice, not cheap, and its still broken, carbon is strong, but easily compromised and failures tend to be instant and catastrophic, riding carbon is a gambit cheap or expensive, nature of the game, sure most everything that you get for cheap will be more prone to breakage but it doesn't mean its not safe, I mean, we live in the USA, the most litigious nation in the world, they ain't gonna be selling bikes that will just explode, unless your Mavic, of coarse and they're french

To be fair, the first post on the page is titled "The result of a 50+ km/h crash." I think cheap, boutique, or bamboo you are facing good odds of failure when that happens, or when you are "going 26mph when [you] hit the windshield with [your] head." Not that those are all crash failures, but many of the dramatic ones are (and many have no explanation at all). The site definitely has a very "this is what you get for riding carbon" sort of sentiment.

The Planet X is FINE. Good for track or street use. I had one all of last year, and I'm a "big guy" at 240 lbs. If it can handle the Gs and wattage from sprinting that I put on it on a bumpy track, it can handle basic street riding and commuting.

Please consider that mid-level and up road bikes are just about all carbon these days, too. Some are the "cheap"-er carbon that people speak of, and those bikes hold up to commuting and road riding/racing just fine.

I wouldn't do tricks on ANY track bike. That's what BMX bikes are for. If you are looking to do tricks, don't be surprised if ANY track bike breaks.

Stop spreading the false rumor that carbon is bad. Aluminum went through the very same drama 4-5 years ago. AL is OK now. Aluminum tubing hasn't changed, just perceptions.

You must be young. I can recall the first Kestrel frames, and Trek's attempts at bonding carbon to aluminum. I ride new steel.

A review of the Planet X.

Bear in mind that the seatpost issue and the tire clearance issue has long since been addressed in subsequent batches of the bike. This review is from summer 2008:

I had a Trek with carbon tubes and AL lugs. It creaked and squeaked like crazy. I remember Kestral, too. But the conversation isn't about carbon fiber bikes from 15+ years ago. Things are different now. Fortunately for some and unfortunately for others (from a business point of view), Asian manufacturers have figured out what to do and how to do it cheaper.

I recall reading an interview or either the top guy from HED or Zipp discussing how they spend millions of dollars designing, developing, and prototyping carbon fiber parts just to have an Asian knock-off shop melt/bake the resin off, expose the layup (the secret), copy the layup, and produce knock-offs within months. Knock-offs that really aren't that bad.

At Interbike 2008, I talked to a guy who had his product and brochures out on display on Wednesday. By lunchtime Thursday, one of the Chinese vendors was offering the same item in a full color brochure. They had the balls to scan his images for their brochure.

For those wondering...

This is like a company designing and making a jacket then a knockoff company buying ONE of the jackets, cutting away the stiches and identifying all of the little pieces that comprise the jacket, reverse-engineering a blueprint, and using that blueprint to mass produce knockoffs.

That's pretty much how all knockoffs work, shoes, purses, clothing, etc...

D*amn! Yeah, that takes balls.

Further, these companies make "private label" gear. Basically, ADD-YOUR-COMPANY-NAME-HERE product lineups.

For example: The EDge and Siegler track bikes are of the same mold. They may use different carbon layups, but it's the same mold.

Also, I *think* the same goes for Dolan and Teschner high-end bikes ($3,000 frame/fork). I can't recall which models were identical. Also the new Fuji Track Elite and Dolan Forza share parts of the same mold, too. One licenses to the other.

Isn't that what they said about BMX bikes when they first came around?
"You're not supposed to do that on a bike"
Then the BMX industry and products themselves became specialized for tricking and durability.
Same goes for the evolving FG freestyle nowadays (I guess only if you see those as "track" bikes, or a branch-off)

That's true.

But that the time, there were no alternatives. The closest related equipment was a real motocross motorcycle.

Except for the high-end stuff, the BMX bikes in the 80s were crap. Then they became 45lb tanks in the 90s.

Now riders have 20" BMX bikes and 24" cruisers to use for such.

I guess it depends on what the riders (and their audience) think is interesting. Is getting air interesting? Or is it the fact that you are getting air on a track bike that makes it interesting? Because if you are looking to get REAL air then you'll get more of it with a BMX. That pretty much goes for 99% of tricks out there. Them's just the facts.
