Since it’s early days, Tyrell have pushed the envelope in making continual improvement in their products and designs.
The quest towards making a better design isn’t merely an exercise in improving the look but also in the performance the product delivers.
Case in point is the distinctive Tyrell frame design that’s the culmination of many sketches and prototypes.
A design that delivers in both performance and looks meeting the parameters of a light weight yet stiff and responsive frame.
The Tyrell CSI is another case in point. This is the lightest Tyrell production bike and was derived from the earlier and now discontinued SI model.
The SI was a lightweight bike but a side effect of the light weight from the thin tubing was comfort on long rides was found wanting.
In an effort to make a more forgiving ride and improve high speed stability, Mr Hirose went back to the drawing board and came up with the design of the carbon SI or CSI.
Changing to larger wheels from 406 to 451 and changes to the wheelbase made the bike inherently more stable at speed. To address the ride comfort and yet keep the weight down, the new frame design incorporated a full carbon rear triangle that served to dampen road vibration, maintain stiffness and reduce weight.
This quest to improve is also seen in some unique components.
The folding fork design found on the Tyrell FX and FSX along with the creative solution to the folding stems solved the issue of space and keeping the folded dimensions compact, while allowing the folding to take place around the frame, keeping the frame rigid, rather than having the frame be part of the folding mechanism.
Other seemingly innocuous small components reflect the incessant drive to improve. The belief that by paying close attention to detail, to materials adn my continually making fine improvements, perfromance improves continually.
The newly introduced Tyrell double seat clamp is a great example of this - clever design whereby separate clamping forces can be applied to the seat post and seat clamp. Very useful when using carbon seat posts where slippage can be an issue.
The Tyrell V stem is another design masterpiece where extreme stiffness and distinct design come into play. An example of design that works.
The hallmark of this quest for improvement and quality is the personal seal of approval found on every Tyrell bike frame.
This serves as a point of assurance and quality that every Tyrell is a unique product that’s been thoroughly tested and born Hirose-san's vision of the perfect Mini-Velo
