Interestingly, whilst some of the parts are older than my Dad (yes, really!) a lot of them are still, relatively speaking, quite light!!! And this is coming from someone who has owned £7000 6kg super bikes!
Here is a breakdown of what I have....
Frame: Stuart Purves built, 59cm c-c, 531 tubing. 1890g
Forks: Stuart Purves built, 531. 794g
Headset: Bayliss Wiley steel. 127g
Front wheel: Normandy hub/Weinmann rim/ACI spokes/Michelin tyre, tube + tape 1700g
Rear wheel: Campagnolo hub/Dunlop rim/ACI spokes/Michelin tyre, tube = tape 1720g
Freewheel: Regina 5speed 362g
Chain: TBC
Bars: GB sprinter style 344g
Stem: TBC
Saddle: Brooks B17 460g
Seatpost+clamp: Airlite layback 274g
Chainset: Williams with 47T single ring 679g
Bottom bracket (no bearings): Bayliss Wiley 297g
Brake calipers: Weinmann QR 322g
Brake levers: Campagnolo Gran Sport 192g
Gear lever: TBC
Rear mech: Campagnolo Gran Sport 301g
Pedals: Williams (I think) with Christophe clips+straps 579g
Bar tape: TBC
Total (so far) 10.041kg (or 22lbs if you prefer)
EXTRAS:
Mudguards: Bluemels Club Special 428g
Pump: Bluemels alloy 130g
Lamp bracket: TBC
What I find interesting is where some things are much, much heavier, eg; the pedals weigh a ton, others are very reasonable.
Take the seatpost, whilst being competitive even by todays standards, it has all the weight in the steel clamp at the top, making it feel quite unbalanced.
I am very happy with the frame and fork weight.... it is much lighter than my 1995 Raleigh M-Trax 531 frameset!
I would guestimate that the missing parts will come in at around 850g (chain 350/gear lever 100/stem 300/tape 100), giving a total of 10.891kg for the bare bike.
With mudguards, pump and lamp bracket (c.50g) a total will be circa 11.499kg, thats 25.3lbs in old money. Not bad for an equipped steel bike that's older than my parents!
