I rode my Cell Bikes custom fixie (set up as a singlespeed) in the 100 km Brisbane to the Gold Coast Cycle Challenge. My total distance in the saddle for the day was 125 km, including riding to and from the ride. I averaged 30.9 km/h for the 100 km Brisbane to the Gold Coast Cycle Challenge part of the ride.
This particular Cell Bikes custom fixie was purchased in 2011 and has 4130 cromoly frame and forks. I have fitted my Cell Bikes singlespeed with Shimano PD-R540 SPD-SL pedals, Halo Aerorage track wheels, Vittoria Rubino Pro tyres, a Selle Italia SLS Kit Carbonio Flow saddle, and an extra water bottle cage on the down tube using Elite VIP bottle cage clamps. I also carry a Top Peak saddle bag and a Maxxis Compressor micro pump mounted under the bottle cage. Otherwise, the bike is pretty standard including 46/16 gearing.
