Black/cream. Ultegra 10 speed triple Sti HT2 transmission thoughout, latest XT hubs on Open Pro CD with Michelin Pro Race3, Ultegra quality 57cm brakes, narrow guards. Believed to have covered less than 500 miles from new and near mint.
By my approximate measurements virtual top tube is 57cm c2c, actual seat tube is 48cm c2c, virtual seat tube (e.g. if it had a horizontal top tube) would be approximately 55cm - I guess therefore that this would be Thorn's size 550. Fits me perfectly at 5'8" would say suits rider 5'6 to 5'11. £895.
Will post anywhere mainland UK at cost.
