He is obsessed with keeping up to date with all the latest tech, is fixated with the smallest details and is known for his unique opinions.

Oscar prefers lightweight road and gravel frames with simple tube shapes, rather than the latest trend for aerodynamics and full integration. He is particularly fond of workshop tool exotica and is a proponent of Campagnolo groupsets. Oscar has a BA degree in English Literature and Film Studies and has close to a decade of cycling industry experience, initially working in a variety of roles at Evans Cycles before joining Carbon Bike Repair. I tried to flick through the pages, but the copy was so.
His favourite rides are epic road or gravel routes, and he has also caught the bikepacking bug hard after completing the King Alfred’s Way and West Kernow Way. Worse, it was so scuffed and filthy that it might have spent most of its life stuck up a chimney. He’s since been indoctrinated into gravel riding and more recently has taken to the dark art of mountain biking. He has been an avid cyclist since his teenage years, initially catching the road cycling bug and riding for a local club. Oscar Huckle is a technical writer at BikeRadar. Presta valves will close automatically, but the sprung Schrader valves are usually held open by a pin in the pump valve attachment (this means you don’t need any extra effort when pumping to overcome the pressure exerted by the spring). If it wasn’t there, the pump would just shoot open again. To prevent the pressure in the tyre leaking back out, the second check valve at the base of the pump closes. You extend the pump again, the check valve opens to refill the chamber with air and you repeat the process. That pressure increases until it exceeds that inside the tyre.Īt this point, a second one-way valve will allow air to flow from the pressurised pump chamber into the tyre.
On a pump’s downstroke, a check valve (that allows air flow in one direction) seals the piston chamber, resulting in air being pressurised as the pump is compressed. This ‘overpressure’ forces air into the tyre, increasing its pressure too.Ī pump is just a manually actuated piston. The operating principle is simple you increase the pressure inside the pump until it exceeds that inside the tyre. Nick Clark / Our MediaĪ pump gets the air into your tyre. Some pumps feature rubberised handles for improved grip.
