Stealth Pro Carbon 650 Frame
Our multiple award and race winning full carbon clock killing aero frame has just picked up it's 3rd bike of the year award from 220 magazine. The full size 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. This version packs all that performance into a specific small rider sized frameset.
Smaller 650c (rather than 700c) wheels accelerate faster and they fit better into the fit and handling requirements of smaller frames. This makes our 12k Carbon fibre Stealth Pro 650c the perfect solo speed frames for pocket rockets who rightly don't think they should have to compromise.
Naturally wind dodging, fast, stiff and super responsive all at a cost that's below most alloy competitors. It won't beat the snot out of you when you ride it either. Add our 650c aero forks and your choice of carbon wheels and/or pro quality custom sized kit and nobody puts baby in the corner.
Note: The frame does not include forks, seatpost or barrel adjusters. These should be purchased separately.

Sizing Guide
Designed in collaboration with Dan Empfield, the renowned slowtwitch guru of 650 bike geometry, the 650 stealth comes with a 78 degree seat angle and is designed for smaller riders of around 5 foot 6 or less. This finally means that smaller riders can get a bike to fit them without the compromises and problems associated with 700c versions of small tri bikes.
| Rider Height | Suggested Frame Size |
|---|---|
| 5′0″ to 5′3″ | XX-Small |
| 5′3″ to 5′6″ | X-Small |
Sizing Notes
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 get 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.
