Is a higher tyre pressure faster? Is a lower pressure more comfortable? Emma conducts an experiment to determine the fastest tyre pressure on a rough road surface. She tested all the way from 119 psi (8.2 bar) to 29 psi (2 bar), the results were surprising!


Register your interest in the GCN Club: 

In a lab environment, a higher tyre pressure shows decreased rolling resistance, but this is a totally different matter out on the road. Emma admits in hindsight that she may have made some changes to the experiment to make the results a little more reliable. However, the data still highlights a very interesting trend and definitely suggests that the old-school beliefs about tyre pressure may be outdated. We hope this might inspire you to conduct your own little experiment. If you do, let us know how it goes and what data you discover!

What tyre pressure do you use on your bike? Let us know in the comments. 👇

GCN Tech's Unboxing is back, with a bit of a twist, as it's a box! That's right, we're taking a look at the Topeak PAKGO X Bike Box and showing you exactly how to pack your bike for your long awaited cycling holidays. 

If like many of us you’re heading off for a summer holiday this year, maybe you’re off to ride in sunnier climates, you’ll probably be wanting to take your bike with you. But few things bring as much dread to the holiday-going cyclists as flying with their bike. Packing it, lugging it through the airport, surrendering it to baggage handlers, its enough to give you nightmares. Well that’s where our latest unboxing comes in! We’ve got a Topeak PackGo X bike box to give away!!

The PackGo X is Topeak’s first foray into the world of bike boxes, and we reckon it looks like it could be a winner! 

One of the neatest features of this bag is this, an internal frame that the bike fits on and then mounts inside of the box. By itself that’s a pretty useful and secure way of packing your bike, but the Topeak mount can actually be removed from the box and set up as a sort of mini workstand! This just makes it so much easier to break down and reassemble your bike when travelling. Pop the pedals off and mount the bike into the frame. 

The PackGo comes with mounting adaptors for standard quick release and 12x100mm Thru-Axles, as close as can be called a standard for road bike disc brake hubs. The PackGo also comes with a Dummy hub/chain keeper for the real hub to stop your chain rattling about and damaging your frame in transit. I think Simon would be a fan of that one! Personally I think the way the rear hub switches between different axle settings is particularly neat I think.

Emma was at the OVO Energy Women's Tour and asked many of the top female professional riders - what was your hardest day on the bike?

Bike racing is a tough sport, meaning our interviewees didn’t have to think for too long before they could remember a hard day on the bike! Some riders spoke of races that were held in less than ideal conditions, others even mentioning some especially hard training rides. All in all, it’s fair to say these riders are pretty tough!

The GCN Tech Clinic is back and this week Jon answers your questions around covering helmet vents for aerodynamic advantage, upgrading your groupset to Di2 and whether you need a speed sensor for increased speed data accuracy.

There are lots queries Jon answers this week, including whether greasing a quick release skewer is necessary, how to properly clean your rim brake track and whether you can run tyres of differing widths. Jon also refers to the UCI rules in relation to the taped vents, showing an old DIY project of his where he created a fibreglass helmet cover!

Ask The Pros is back with a special Canyon//SRAM edition. Emma caught up with the riders at the OVO Energy Women's Tour asking them which aspect is most important in their bike fit. 

Bike set-up covers various measurements including handlebar reach, saddle height, and saddle to bar drop. We asked a number of Canyon//SRAM riders, including Hannah Barnes and Kasia Niewiadoma, which aspect is most important to them and how specific their fit has to be. We saw some interesting responses in this video and hope that you enjoyed learning more about these professional riders positions.
