Part specs/weights for rebuild....

Well I have got most of the parts that came on the bike as I got it but I also have a range of parts that I have either sourced myself (mainly via eBay) or have been kindly donated to me.

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!

Call to Mercian

Well I have been sorting through all the parts that I have and I am basically sorted now. I still need a down tube lever but think I have found a good one.

Yesterday I rang Mercian Cycles in Derby and checked all their terms for frame renovation. So next Friday (payday) I will box up the frame and have them collect it ready for the work to be done. It should take around six weeks.

I am having.... a new Campag' rear mech hanger fitted; a broken braze-on removed from the down tube; frame stripped, primed and repainted in light blue enamel (Mercian colour number 24) and lug lined with gold polychromatic (Mercian colour number 10). I am then having "STUART PURVES" made in block white lettering for the down tube as well as a set of Reynolds 531 transfers fitted.

It should match the mudguards nicely and look like this..............
