Do the following 2005 Shimano 105 components differ very much from the current Shimano 105 components?

1) BRAKE LEVERS - Shimano 105, STI
2) FRONT DERAILLEUR - Shimano 105, 31.8mm clamp, bottom pull
3) REAR DERAILLEUR - Shimano 105, long cage (triple)
4) SHIFT LEVERS - Shimano 105, STI, flight deck compatible
5) CASSETTE - Shimano 105, 9-speed, 12x25t

Thanks
