Curvaceous number from Wales
Paulus Quiros is a partnership between Jonathan Paulus and José Quiros, who design and build handmade steel bikes from their workshop in Swansea. A signature feature of the team’s handiwork is a handcrafted steel plate between the seatstays and top tube, but it’s the curvaceous geometry on their singlespeed that attracted attention at Bespoked. “When we first showed this to cyclists, many thought it would feel really rigid upfront,” says Paulus. “But actually that shape moves the stress to mid-tube in a rather predictable manner. In a metaphorical way, it’s almost like you enjoy a touch more flexibility in the middle of the downtube for added comfort. Ultimately, this shape maximises power transfer, albeit despite the standout tubing, key is that you get the dimensions of the seattube right. That knits things together.” The ‘Pike’ design’s constructed from Reynolds 853 double-butted steel and 4130 aerospace chrome-molybdenum tubing. Beautiful tig welding melds things together, although Paulus Quiros are also adept at fillet and lug brazing. The elegant crankset’s supplied by Campagnolo, specifically from their lauded Record range. Paulus Quiros also showcased a bike they’d designed and built for endurance cyclist Dominic Irvine, with the unique aero 29er required to withstand the punishment of a cyclist who often racks up over a thousand miles of riding each week. “That’s why we used Reynolds 953,” Paulus explains of the bike that’s notable for a fork that propels forward acutely before becoming shallower halfway down. “You can’t maintain a TT position on a traditional 29er because it would behave terribly,” he adds. “So the geometry’s completely changed.” There’s great footage on YouTube of Dom testing the bike in Afan Forest.
