How to measure any manufacturer's bike frame
Standard frame measurement terms:
- ST: Seat Tube: Measured from the center of the bottom bracket along the center to a point near the seat post binder. The exact location of this point may vary between manufacturers depending on the frame design. The main purpose of this would be as a reference point and, if located at the seat binder, would indicate whether your favorite seat post would be clamped above the minimum insertion line.
- TT: Top Tube: Measured from the frame size point horizontally to the steering tube axis.
- ST
o : Seat Tube Angle: The angle of the line passing through the bottom bracket and frame size point relative to the horizontal.
- SB: Setback: (used as a more accurate way to measure seat tube angle) the horizontal distance from a vertical line passing through the bottom bracket to the frame size point.
- HT o : Head Tube Angle: The angle of the steering axis relative to horizontal.
- HT: Head Tube length: The length of the head tube (not including headset components)
- Measure the seat tube from the center of the bottom bracket to the point where you want the seatpost to exit the seat tube. Subtract 1 cm. That is the seat tube length and reference point for the next two measurements.
- With the bike on a level floor, measure horizontally from the seat tube length point to the center of the steering axis. That is the effective top tube length.
- If you don't have the published seat tube angle for your frame and you don't have an accurate protractor or "Angle Finder", you can measure setback. To do this, hang a plumb bob from the top tube so it passes through the center of the bottom bracket axis. Put a piece of tape on the top tube to mark the spot. Measure horizontally from this line back to the frame size point. That is the frame setback. Seat tube angle can be calculated from setback and seat tube length or you can simply compare setback directly.
- Measure the overall length of the head tube, not including any headset parts. Measure the spacers between the headset and the bottom of the stem that you will be using. On a new frame, increase the head tube length by the total thickness of spacers you wish to remove.
- Measure from the floor to the top of the top tube at the point where you would stand over the bike. That is the standover height for that bike.

RTS TTR6 2010
TTR6 2010
For 2010 RTS is producing a limited Golden Yellow and Arctic White TTR6 model. Only 100 frames will be produced in these paint schemes. The TTR6 model is our popular road-racing model where we sacrifice nothing in terms of stiffness, weight and comfort.
From its ultra stiff box-shaped down tube to the simple yet efficient design of the seat stays and chain stays, it will make climbing seem effortless and give authority when in the sprint finale.
The TTR6 being our lightest frame will make even the hardest of roads feel ultra smooth. Although it is considered a lightweight frame, its ability to transfer power is anything but light.
With its massive down tube cross-section, the frame is built to literally glide up the mountains.
Our ability to squeeze every ounce of stiffness and strength out of less material is a testament to RTS’ knowledge of carbon fiber technology.

TTRX 2010
For 2010 RTS is producing a limited Golden Yellow and Arctic White TTRX model. Only 100 frames will be produced in these paint schemes.
The TTRX model is our multi-functional aero frame set. As a company that prides itself on making exceptionally aerodynamic bikes that save every watt in the wind, we feel that we have not only the knowledge and technology but also the experience that comes with making such a high-performance frame.
Aero frames are the most difficult frames to produce, as they have to do everything. They have to be; aerodynamic, stiff, light and comfortable.
Not too many bikes on the market can say with confidence that they can integrate all of the mentioned characteristics into one machine. RTS Carbon is confident that with its experience and team of engineers, we have successfully created a true multi-functional frame set.
It is aero enough that you can just slip on a set of TT bars and you have a capable time trial machine, yet it is light enough to be used in regular road racing, where qualities like handling and light weight are more important.
Whether you’re racing against the clock, climbing up the steepest mountains or going on a solo attack, the TTRX will definitely be ready for anything you can give it and more.
Features:
- 2010 Limited Edition Color
- Full SRAM Red Component Group
- Only 100 sets limited sets available

Cervélo confirms it will end cycling team

Bike manufacturer to stay involved in pro cycling
Cervélo confirmed today that it would not continue as a title sponsor for its cycling team after the end of this season. In a statement issued late Thursday, the bike manufacturer cited "certain subtle changes in the rules that govern pro cycling" which meant the team would have had to increase its budget to ensure it would be able to participate in the sport's biggest races. Cyclingnews reported yesterday that the team's future was uncertain after a number of riders were linked to Garmin-Transitions for next year.
"This is not something with which we are comfortable," the statement said. "We were okay with the significant commitment we originally made to the team, but to increase it is not prudent."
The press release did not directly state that it was ending both the men's and women's professional teams, but Cyclingnews understands from its sources that the women's programme will continue. Sources have confirmed that the riders were notified of the news via email on Wednesday by the team management and that the women were assured that the team would continue for next year, although Cervélo have not confirmed this.
Gerard Vroomen, co-founder of Cervélo, set up the men's Pro Continental team at the start of the 2009 season, signing 2008 Tour de France winner Carlos Sastre, Thor Hushovd and a host of other talented riders. The team had a spectacular debut season, winning stages and the green jersey in the Tour de France, stages in the Vuelta and Giro, as well as seeing Heinrich Haussler break through as a major force in one-day racing.
The team were unique in the sense that they combined product development and brand awareness with winning as their main goals.
The team remained Pro Continental in 2010 and were set to carry on as such for next year. However, the UCI modified its rules for participation in the World Calendar races for 2011, and it seems these changes would preclude a Pro Continental team from guaranteed participation in the Tour de France.
Sastre was the first to announce his departure from the team well before rumours of the squad's demise became rampant. His move, coupled with the fact that no new faces were brought into the squad meant that Cervélo were already short of numbers for next season. There was also speculation as far back as the spring that the team were in financial difficulty. However, news of the team's demise still came as a shock to many of the riders within the team.
Since then, the bike manufacturer has been linked with the Garmin-Transitions team as a possible replacement for the American squad's Felt sponsorship, with Transitions dropping from the second sponsor slot and Cervelo taking over in their place. Neither team confirmed this. However, the Cervélo statement said, "We look forward to continued involvement in pro cycling at the highest level with an emphasis on product R&D, as we have since 2003. To that end, we will announce the details soon."
Cyclingnews sources have also confirmed that several of Cervelo's riders have begun negotiations with Garmin, including Haussler, Hushovd and a handful of their other Classics riders.
