My Cell Bikes fixies (I have two) have been through many guises, including a singlespeed ridden on the 100 km Brisbane to Gold Coast cycle ride at an average speed of more than 30 km/h, ridden up Mt Coot-tha, and configured as a sit-up town bike with swoopy bars.
Recently I have been using a Cycling Queensland track hire bike to train on Chandler Velodrome in Brisbane, Queensland. I was keen to ride one of my own bikes on the track and had heard of other people riding Cell Bikes fixies on velodromes. I stripped my Cell Bikes fixie of brakes and the water bottle cage, replaced the riser bars with PRO PLT compact drop bars, and put on some 165 mm 144 BCD Andel RSC1 cranks.
I took the bike down to a training session to see whether it would be okay to ride on the track. My main concern was that with a 65 mm bottom bracket drop, the bike is at least 7 mm lower than a typical bunch-start track bike. However, with the shorter cranks, I was able to get enough clearance to ride safely around Chandler Velodrome.
Chandler Velodrome, being an outdoor 333 metre track, has relatively shallow banking at around 30 degrees for an international standard velodrome. Indoor international standard velodromes are typically 250 metres (or less) and have banking of at least 42 degrees. On the other hand, many regional velodromes in Australia have track banking much shallower than Chandler Velodrome.
My point is, if you are thinking of putting a Cell Bikes fixie on the track, check with your local club first. Depending on the track specifications, and how strict your club is, you may be able to put a Cell Bikes fixie on the track and safely have heaps of fun for not very much money!
