Bigger, grippier, lighter and as tough as ever. The Penthouse Flat MK5 pedal is here!
When our journey started some 17 years ago on the slopes of Schladming in '03, we didn’t stop to think about the future. The prototype MK1 Penthouse Flat that debuted that weekend inevitably paved the way for the MK2 in ‘07, the MK3 in ‘09, and the MK4 in ‘14. While much has changed in that time, our focus on building the toughest and grippiest flat pedals on the market remains the same.
Our goals for the MK5 mountain bike pedals followed the same design and development path as every other pedal before it; utilise any advances in materials and manufacturing, balance the weight and durability, and maximise the amount of grip. From the MK4 to the MK5, we shed 65 grams per pair. The platform footprint was increased by 7%, the dish by 1mm and the pin width was decreased by 0.5mm.
Refinement
Taking on feedback from the MK4 mtb pedals we tried a number of different Q-factors to balance the foot’s position in relation to the cranks.
With every flat pedal shoe on the market at our disposal, we experimented with different platform sizes, pin widths, and pin heights to maximise grip underfoot.
It was of the utmost importance that the MK5’s internals represents the best of the best. To do this we specced the most wear-resistant bushings from Igus. Their "Endurance Runner" material - W300 - was a clear winner as this gave unrivalled resistance to external influences. Mud and water ingress is kept at bay with a full-contact oil seal. This keeps grease in and contaminants out even in the harshest of conditions. This configuration of quality parts is why the Penthouse series has a reputation for outstanding longevity.
