Extra light rims and 2:1 ratio carbon hubs for exceptional acceleration and climbing.

For this wheelset I chose an extra light set of rims, with a 27.5mm semi-toroidal profile to cut through the wind – not only for speed, but for handling purposes too. In fact they use the same rim moulds as the Elite model – it’s such a great rim profile. But I specced a higher grade carbon to be added to the layup. This saves a lot of weight whilst adding stiffness. Because it’s rotational weight you’re saving the difference in acceleration is something you can actually feel – they bring a bike to life!

Often people think that light weight means reduced strength – this simply isn’t the case when a higher grade of carbon is used. Basically the higher grade carbon is stronger. This means the fibres themselves are made thinner. Which means when they’re woven into sheets the sheets themselves are thinner and lighter. Of course, they’re tubeless ready and easy to set up. 

For 2019 I’ve upgraded the straight-pull hubs to a 2:1 ratio design. These add stiffness and durability over a standard design. I’ve had these made in the same factory as the Elite model. The big difference between the two is that these use a carbon fibre shell. Again, this saves a bit of weight and adds extra stiffness. They also look rather good….

They’re an exceptionally high specced wheel set, equally suited to race day use and sportive duties – or just a really nice set of wheels for your best bike!
