Aluminium Dolan track frame fixie for sale. The frame measures 51 cm from the centre of the bottom bracket to the top of the seat tube - this sounds small but I am about 5'8" and it fits me fine. It has a shimano front brake because I use it on the road. The bike was built by Fred Baker in Bristol 6 years ago and is still in good, clean working order. The chain and bottom bracket were replaced recently.
