Race focussed Time Trial model with custom geometry.
DESCRIPTION
The Éimear (a Gaelic name meaning 'Swift') model is the result of an extensive development process over a number of years. The result is a time trial bike that offers excellent aerodynamic performance whilst accommodating custom geometry. I wanted to create a bike a bike that offered the aerodynamic performance of a modern 'off the shelf' TT build with the benefit of optimised fit and handling characteristics: These are so often overlooked in a data dominated market but offer a compound performance benefit in ensuring that a rider can remain in an optimised, and ultimately faster, position for a greater proportion of their ride.
The model was developed over multiple rounds of CFD simulation followed by real world validation. With each build being made to measure it is impossible to provide meaningful comparative drag coefficient data, instead the development focussed on establishing shapes that trended towards an overall improvement in real world performance. By comparison to many modern time trial bikes Éimear has a relatively simple silhouette using shapes and profiles that provide reliable performance across a range of sizes and proportions.
As with all the models that I offer a strong emphasis is also placed on the less quantifiable aspects of the riding experience. Whilst time trial bikes are not intended to provide good comfort I have worked hard to retain the 'smooth yet efficient' sensation that riders so often report from riding the other models that I offer.
