Planet X Stealth Pro Carbon New Logo TT / Triathlon Frame
NOW INCLUDING AERO SEATPOST
Updated version of the all time classic Planet X carbon speed weapon.
Our multiple award and race winning full carbon clock killing aero frame has just picked up its 3rd bike of the year award from 220 magazine. The full 12k carbon fibre machine is also the bike that UK time trial legend Ian Cammish wanted to buy off us on cheque spread before we gave him a job instead. Naturally wind dodging, fast, stiff and super responsive, all at a cost that's below most alloy competitors.
Note: The frame does not include forks or barrel adjusters. These should be purchased separately.

The main features of the Stealth Pro Carbon geometry are a short head tube, short top tube and relatively steep seat angle. This geometry is designed primarily to offer great handling, comfort and good aerodynamics when riding on the tri bars.
A well fitting triathlon or time trial bike will typically have a shorter top tube than a road bike for the same rider which draws in the elbows towards the torso to create better aerodynamics and increase comfort.
|Rider Height||Suggested Frame Size|
|Less than 5′5″ (<165cm)||Go for the 650C Stealth Pro Carbon instead|
|5′5″ to 5′9″ (165-175cm)||Small|
|5′10″ to 6′0″ (178cm-183cm)||Medium|
|6′0″ to 6′2″ (183cm-188cm)||Large|
|6′2″ to 6′6″ (188cm-198cm)||X-Large|
All frame size recommendations are approximate. A good fit will also depend on the correct choice of stem length, correct bike set-up for the rider and riding style.
Correct frame size choice can vary greatly with riders torso length. If you have longer legs and a shorter torso, go for a slightly shorter stem. If you think you are borderline between sizes and you have longer legs and a shorter torso, go for the smaller frame size. If you have shorter legs and a longer torso, go for the larger frame size to benefit from the extra top tube length.
As the frame sizes increase, so does the length of the head tube. If you are inflexible or perhaps have a history of back problems, consider going for a larger frame size. This will increase the relative height of the handlebars making the position less “extreme”. The larger frame will also have a longer top tube, so you’ll need to compensate for this with a shorter stem.
