At Matt Bottrill Performance Coaching we’re fortunate enough to get offers of wheel sponsorship quite regularly but, as everyone knows, I’m all about the numbers and if a wheel doesn’t offer any savings over what we’re already using, I’m not interested.
But when I saw the data on the new CADEX 4-spoke front and disc rear I did a double take.
At first I didn’t believe it – I thought 'no way, that can't be right, no one can do that with a wheel'. The team behind the wheels were saying they’d optimised it for zero to 30 degrees of yaw – a much wider range than other wheel brands claim for theirs. So I said, give me those wheels, I’ll take them to the wind tunnel and I’ll find out.
And once I'd done so, I was shocked.
In cycling industry right now, if you can find one or two watts you’re doing well, but with this wheelset we’re seeing anything between five and seven watts when using the CADEX 4-spoke front and rear disc wheel.
As well as working with Lotto-Soudal this winter, I’ve been going to the wind tunnel three times a month and as I've been racking up the wind tunnel time, I've been beginning to see trends. I've learnt that some wheels come into their own when they get to higher angles, for examples 10 degrees of yaw, but it seemed the data from CADEX was right; they’re the fastest at much lower yaw angles and they outperform the others at higher yaw angles too.
We tested them against some of the leading wheel brands in the wind tunnel, until I was absolutly sure these were the best. Once this was clear, was no way I was going to turn them down.
But it’s not just about a wheel’s performance in the wind tunnel – it's also got to be fast and to handle well in the real world. I’ve been training outdoors with the CADEX 4-spoke front and rear disc wheel in my TT bike and I've been putting them through their paces and I can honestly say I’ve never ridden anything like these. They’re simply unbelievable.
Years ago most competitive Time Trialists were riding tri-spokes and four-spokes that were fast on a calm day in zero yaw but unstable in a crosswind. Then 80mm rims came along, which handled well in crosswinds. Now this CADEX wheelset has both the speed and the handling and they’re super stiff too.
Wider rims have been a game changer for aero wheels’ stability because they work better in higher yaw angles. More stability equals more speed. The CADEX 4-spoke front and rear disc have an internal rim width of 21mm (17mm was the old standard) so that a 25mm tubeless tyre, which is what I’m using now, sits really flush for an absolute minimum of airflow separation between the sidewall and rim.
I’ve also been riding CADEX’s road wheelsystems, which come in 42mm and 65mm rim depths. These have aerodynamically optimised carbon spokes and are incredibly light and stiff.
Our A team supported riders will be on CADEX wheels this year and I’m really excited. We’ve got the coaching, we’re giving them the nutritional support, we’re giving them the wind tunnel time and with the CADEX wheels they’ve got the best equipment. It’s all about leaving no stone unturned in the quest for success and I'm confident we can achieve great things.
