i'm playing with the idea of starting a 4000 m track carreer 8)
what are people's suggestions for a good track bike for that purpose?
i think a position as similar as possible to my tt bike would be intelligent, no? is there a carbon frame for track use(like karbona)that can be bought for a reasonnable price?
what are the geometry differences between a tt and a track tt bike?
can i use my zipp front wheel on the track if i put it in the fork with a bolt on axle?
then i would only have to buy a rear wheel.
goals:
-6,8 with race setup and srm
-as aerodynamic as possible(so no custom steel frame to get the geometry)
-not as expensive as possible because this bike won't see many competitions(at least not until i see what's possible for me in this discipline)

As you can see on the pic of Shamus wife; She used a normal LW with an QR. So I guess it isn't a problem to use your zipp front wheel.

Of course it is possible to ride with a quickrelease. Nevertheless this is illegal for trackraces in Holland.

If I was you (and had a little bit of money behind me) I'd look at a BT or a 'Teschner' (I believe the teschner track is a frame they specced overseas, as Dolan (?) has an identical frame/fork/seatpost package from memory)

Quickrealeases are illegal for track races.

But, we can use them in Finland at time trials on track.

About frames, Isaac and Cervelo if you want to have light frame.

BT and Look if weight & money does not matter.

If you can afford a pair of LEWs, you can afford an allen key skewer and be legal (and safe)

Well not at all cheap but Cervelo makes a track specific version of the P3 Carbon...not going to do a heck of a lot better than that in the aero department: http://www.competitivecyclist.com/za/CC ... CT.ID=4114

And of course there is the Look.

There are a couple of CF TT bikes with horizontal dropouts from places like Pedal Force...maybe something like that could get you there: http://pedalforce.com/online/product_in ... 7dbd6b8461

Allen key skewers work well for the front wheel.

Position tends to be the same, maybe a few extra mms of hight for the seat (feels right to me). Remember track bikes will often have longer head tubes than road TT bikes as the BB is often higher - unless its a pure TT/IP/TP machine like a FES or Walser

Simon,

You might want to look at a Fuji Track Pro. It is not carbon, but it is very light and inexpensive. A complete bike is $1200.00, weighs 15.0 Lbs. with some rather heavy parts like the fork, wheels, seatpost, bars, stem etc. The frame has an aero downtube, seattube, and rear stays. The rear wheel is drafting the seatube like many TT designs. You can buy the frame separately.

Boy would I love to own a carbon track bike, but it seems that the prices are very high for most of the frames, like the Cervelo P3 or Pinarello track frames.

Kabona does sell a carbon track frame:

Wow now I am learning a bunch about cool track frames.... That Blue frame is gorgeous, and I think the aluminum is a good choice for track. The Kabona frame and the Pedal Force frame look pretty similar and both look cool, but I wonder if the carbon is of any benefit on a track.

On the track, you could argue that ride quality (not handling) is of negligible importance, as the tracks I have seen look relatively perfect in terms of surface quality. So the aluminum is probably thinner and stiffer to make an aero frame out of no?

the blue frame looks awesome, any idea about weight?
isaac seems to be a good idea, have a source to get them "cheap and quickly".
the pedal force is what i have for the road, but aren't bb and rear wheel spacings different on the track?
i've already thought about the fuji frame more than once, but i'm asking myself if i could adapt the road tt position to this geometry, the top tube seems a bit long/seat tube angle to flat compared to my tt frame.
what bar should i get?i have hed on the road, but they have brake levers integrated, so they fall out. guess stiffness matters here?
